Background/Objectives: The quantitative flow ratio (QFR)-based functional Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score (FSSQFR) combines coronary arteries’ anatomy and physiology. Methods: We performed an offline FSSQFR calculation in all-comers undergoing coronary angiography in a single center. Based on the tertiles of SYNTAX Score (SS), patients were divided into low-, intermediate-, and high-risk groups with the following cut-offs: SS/FSSQFR < 13, SS/FSSQFR: 13–21, and SS/FSSQFR: >21. The primary endpoint was the predictive value of the FSSQFR of the composite endpoint of all-cause death, myocardial infarction, ischemia-driven revascularization, hospitalization for heart failure, and life-threatening arrhythmias after the follow-up period. Results: This study included 410 patients. SS and FSSQFR were measured for all patients. After calculating FSSQFR, the risk stratification changed in 11% of the study population; more specifically, 26.8, 32.7, and 40.5% of patients were classified as high-, intermediate-, and low-risk, respectively. After a median 30.2 (25.7–33.7) months follow-up period, we recorded 85 events of the primary outcome. The high-risk FSSQFR group compared to the low-risk group had a significantly higher rate of the primary composite outcome (HR: 1.95, 95% CI 1.33–3.34, p = 0.016). Conclusions: In our study, patients classified as the high-risk FSSQFR group had a significantly higher rate of cardiovascular adverse events.

Background: Despite recent guidelines appropriate lipid-lowering treatment (LLT) remains suboptimal in everyday clinical practice. Aims: We aimed to describe clinical practice of use of LLT for at least high CV risk populations in a Hellenic real-world setting and assess how this relates to the European Society of Cardiology treatment guidelines. Methods: We analyzed data from a retrospective cohort study of the National Registry of patients with dyslipidemia between 1/7/2017 and 30/6/2019 who were at least of high CV risk and filled a dual or triple lipid-lowering treatment (dLLT, tLLT) prescription. The primary outcomes of interest of this analysis were to report on the patterns of LLT use in at least high CV risk patients. Results: A total of 994,255 (45.4% of Greeks on LLT) were of at least high CV risk and 120,490 (5.5%) were on dLLT or tLLT. The percentage of patients with reported statin intolerance ranged from 2 to 10%. While persistence was reported to be satisfactory (>85% for both dLLT or tLLT), adherence was low (ranging between 14 and 34% for dLLT). In 6-month intervals, the percentage of patients achieving a low-density lipoprotein cholesterol (LDL-C) target below 100 md/dL ranged from 20% to 23% for dLLT and 34%–37% for tLLT. Conclusions: The prevalence of at least high CV risk patients among patients receiving LLT in Greece is substantial. Despite the high persistence and probably due to the low adherence to treatment, LDL-C remains above targets in more than two thirds of patients.

Background: The widespread use of fluoroquinolones has been associated with the formation, dissection, and rupture of aortic aneurysms. Arterial biomarkers are established predictors of cardiovascular events. The present study was designed to investigate the effect of quinolones on arterial stiffness and aortic size for the first time. Methods: We studied 28 subjects receiving short-term (Results: Subjects had similar values of arterial biomarkers, blood pressure measurements, and aortic diameters at baseline. At follow-up, no significant change was observed between the two groups regarding the hemodynamic parameters and arterial biomarkers (p > 0.05 for all), i.e., cfPWV (7.9 ± 2.6 m/s for the control group vs. 8.1 ± 2.4 m/s for the fluoroquinolones group; p = 0.79), AIx@75 (22.6 ± 9.0% for the control group vs. 26.6 ± 8.1% for the fluoroquinolones group; p = 0.09), and aortic diameters. Conclusions: To our knowledge, FRAGILES is the first study to provide insights into the possible effects of fluoroquinolones on arterial biomarkers, showing that, at least in the short term, treatment with fluoroquinolones does not affect aortic function and diameter.

Background: Outcome data regarding the administration of tenecteplase (TNK) to acute ischemic stroke (AIS) patients presenting in the extended time window are limited. Objectives: We aimed to assess the current evidence regarding the efficacy and safety of TNK at a dose of 0.25 mg/kg for AIS treatment in the extended time window. Design: A systematic review and meta-analysis was conducted including all available randomized-controlled clinical trials (RCTs) that compared TNK 0.25 mg/kg versus no thrombolysis in AIS patients presenting in the extended time window (>4.5 h after last-seen-well or witnessed onset). Data sources and methods: Eligible studies were identified by searching Medline, Scopus, and international conference abstracts. The predefined efficacy outcomes of interest were 3-month excellent functional outcome [defined as the modified Rankin Scale (mRS) score ⩽1; primary outcome], 3-month good functional outcome (mRS ⩽ 2), 3-month reduced disability (⩾1-point reduction across all mRS scores). We determined symptomatic intracranial hemorrhage (sICH), any ICH and 3-month mortality as safety endpoints. A random-effects model was used to calculate risk ratios (RRs) and common odds ratios (cORs) with corresponding 95% confidence intervals (CIs). Results: Three RCTs were included comprising 556 patients treated with TNK versus 560 controls. TNK 0.25 mg/kg was associated with a higher likelihood of 3-month excellent functional outcome compared to controls (RR = 1.17; 95% CI = 1.01–1.36; I 2 = 0%), whereas there was no difference regarding good functional outcome (RR = 1.05; 95% CI = 0.94–1.17; I 2 = 0%) and reduced disability (adjusted cOR = 1.14; 95% CI = 0.92–1.40; I 2 = 0%) at 3 months. The risks of sICH (RR = 1.67; 95% CI = 0.70–4.00; I 2 = 0%), any ICH (RR = 1.08; 95% CI = 0.90–1.29; I 2 = 0%) and 3-month mortality (RR = 1.10; 95% CI = 0.81–1.49; I 2 = 0%) were similar between the groups. Conclusion: Based on data from three RCTs showing increased efficacy and a favorable safety profile of TNK in the treatment of AIS in the extended time window, continuing efforts of ongoing RCTs in the field are clearly supported. Trial registration: PROSPERO registration ID: CRD42023448707.

Background The aim of this study was to develop a structured 2‐step approach, based on noninvasive diagnostic criteria, that led to an electrophysiology study in patients with unexplained syncope. Methods and Results Two independent cohorts were used: the derivation cohort with 665 patients based on electronic health record data to develop our 2‐step diagnostic approach, and the validation cohort based on 160 prospectively screened patients, presenting with unexplained syncope episodes. Noninvasive electrocardiographic and imaging markers and an electrophysiology study–based invasive assessment were combined. A positive diagnostic approach according to our study's prespecified criteria resulted in a decision to proceed with a permanent pacemaker/implantable cardioverter‐defibrillator. The primary end point was the time until the event of recurrent syncope (syncope‐free survival). Number needed to treat was calculated for patients with a positive diagnostic approach. The number of patients with unexplained syncope and borderline sinus bradycardia needed to treat was 5, and the number of patients with unexplained syncope and bundle branch block needed to treat was 3 over a mean follow‐up of ≈4 years. After the structured 2‐step approach, the primary outcome occurred in 14 of 82 (17.1%) with a pacemaker/implantable cardioverter‐defibrillator and 19 of 57 (33%) with a negative approach, with a mean follow‐up of ≈2.5 years (29.29±12.58 months, P=0.03). Conclusions The low number needed to treat in the derivation cohort and the low percentage of syncope recurrence in the validation cohort supports the proposed 2‐step electrophysiology‐inclusive algorithm as a potentially low‐cost, 1‐day, structured tool for these patients.

Background: Greece was recently reclassified from low- to medium-risk country in terms of cardiovascular disease, with 27% of cardiovascular deaths attributed to hypercholesterolemia. EMENO nationwide survey (2013-2016) assessed the epidemiology of dyslipidemia in the general population in Greece. Methods: A random sample of adults was drawn by multistage stratified random sampling based on 2011 census. Standardized questionnaires and blood tests for total cholesterol (TC), low-density (LDL-C), and high-density lipoprotein cholesterol (HDL-C), and triglycerides were used. Hypercholesterolemia was defined as TC ≥ 240/200 mg/dL and/or the use of lipid-lowering drugs, hyper-LDL-cholesterolemia as LDL-C ≥160/130/100 mg/dL and/or the use of drugs, hypo-HDL-cholesterolemia as HDL-C

Recurrent pericarditis is a problematic clinical condition that impairs the quality of life of the affected patients due to the need for repeated hospital admissions, emergency department visits, and complications from medications, especially glucocorticoids. Unfortunately, available treatments for recurrent pericarditis are very limited, including only a handful of medications such as aspirin/NSAIDs, glucocorticoids, colchicine, and immunosuppressants (such as interleukin-1 (IL-1) blockers, azathioprine, and intravenous human immunoglobulins). Until recently, the clinical experience with the latter class of medications was very limited. Nevertheless, in the last decade, experience with IL-1 blockers has consistently grown, and valid clinical data have emerged from randomized clinical trials. Accordingly, IL-1 blockers are a typical paradigm shift in the treatment of refractory recurrent pericarditis with a clearly positive cost/benefit ratio for those unfortunate patients with multiple recurrences. A drawback related to the above-mentioned medications is the absence of universally accepted and established treatment protocols regarding the full dose administration period and the need for a tapering protocol for individual medications. Another concern is the need for long-standing treatments, which should be discussed with the patients. The above-mentioned unmet needs are expected to be addressed in the near future, such as further insights into pathophysiology and an individualized approach to affected patients.

Abstract The effect of metabolic syndrome (MetS) and clusters of its components on central blood pressure (CBP) has not been well characterized. We aimed to describe the effect of MetS and clusters of its components on CBP in a large population and to identify whether this effect differs in men and women. We studied 15,609 volunteers (43% women) from 10 cohorts worldwide who participated in the Metabolic syndrome and Artery REsearch Consortium. MetS was defined according to the NCEP-ATP III criteria (GHTBW, glucose, high-density lipoprotein cholesterol, triglyceride, blood pressure, waist circumference). CBP was measured noninvasively and acquired from pulse wave analysis by applanation tonometry. MetS was associated with a 50% greater odds of having higher CSBP. After controlling for age, male sex, non HDL cholesterol, diabetes mellitus, and mean arterial pressure, only specific clusters of MetS components were associated with a higher CSBP; and some of them were significant in women but not in men. We identified “risky clusters” of MetS variables associated with high CSBP. Future studies are needed to confirm they identify subjects at high risk of accelerated arterial aging and, thus, need more intensive clinical management.

Inherited cardiovascular diseases are highly heterogeneous conditions with multiple genetic loci involved. The application of advanced molecular tools, such as Next Generation Sequencing, has facilitated the genetic analysis of these disorders. Accurate analysis and variant identification are required to maximize the quality of the sequencing data. Therefore, the application of NGS for clinical purposes should be limited to laboratories with a high level of technological expertise and resources. In addition, appropriate gene selection and variant interpretation can result in the highest possible diagnostic yield. Implementation of genetics in cardiology is imperative for the accurate diagnosis, prognosis and management of several inherited disorders and could eventually lead to the realization of precision medicine in this field. However, genetic testing should also be accompanied by an appropriate genetic counseling procedure that clarifies the significance of the genetic analysis results for the proband and his family. In this regard, a multidisciplinary collaboration among physicians, geneticists, and bioinformaticians is imperative. In the present review, we address the current state of knowledge regarding genetic analysis strategies employed in the field of cardiogenetics. Variant interpretation and reporting guidelines are explored. Additionally, gene selection procedures are accessed, with a particular emphasis on information concerning gene-disease associations collected from international alliances such as the Gene Curation Coalition (GenCC). In this context, a novel approach to gene categorization is proposed. Moreover, a sub-analysis is conducted on the 1,502,769 variation records with submitted interpretations in the Clinical Variation (ClinVar) database, focusing on cardiology-related genes. Finally, the most recent information on genetic analysis's clinical utility is reviewed.

Objective: Syncope, whose cause is unknown after an initial assessment, has an uncertain prognosis. It is critical to identify patients at the highest risk who may require a pacemaker and to identify the cause of recurrent syncope to prescribe proper therapy. The aim of this study was to evaluate the effect of permanent pacing on the incidence of syncope in patients with unexplained syncope and electrophysiology study (EPS)-proven atrioventricular (AV) node disease. Methods: This was an observational study based on a prospective registry of 236 consecutive patients (60.20 ± 18.66 years, 63.1% male, 60.04 ± 9.50 bpm) presenting with recurrent unexplained syncope attacks admitted to our hospital for invasive EPS. The decision to implant a permanent pacemaker was made in all cases by the attending physicians according to the results of the EPS. A total of 135 patients received the antibradycardia pacemaker (ABP), while 101 patients were declined. Results: The mean of reported syncope episodes was 1.97 ± 1.10 (or presyncope 2.17 ± 1.50) before they were referred for a combined EP-guided diagnostic and therapeutic approach. Over a mean follow-up of approximately 4 years (49.19 ± 29.58 months), the primary outcome event (syncope) occurred in 31 of 236 patients (13.1%), and 6 of 135 (4.4%) patients in the ABP group as compared to 25 of 101 (24.8%) in the no pacemaker group (p

Abstract We explored whether radiomic features from T1 maps by cardiac magnetic resonance (CMR) could enhance the diagnostic value of T1 mapping in distinguishing health from disease and classifying cardiac disease phenotypes. A total of 149 patients (n = 30 with no heart disease, n = 30 with LVH, n = 61 with hypertrophic cardiomyopathy (HCM) and n = 28 with cardiac amyloidosis) undergoing a CMR scan were included in this study. We extracted a total of 850 radiomic features and explored their value in disease classification. We applied principal component analysis and unsupervised clustering in exploratory analysis, and then machine learning for feature selection of the best radiomic features that maximized the diagnostic value for cardiac disease classification. The first three principal components of the T1 radiomics were distinctively correlated with cardiac disease type. Unsupervised hierarchical clustering of the population by myocardial T1 radiomics was significantly associated with myocardial disease type (chi2 = 55.98, p

Background: Patients with diabetes mellitus (DM) and coronary artery disease (CAD) represent a high-risk population, where comorbidities are common and the progression of coronary heart disease is relatively rapid and extensive. The present survey, conducted nationwide in a Eurozone country, Greece, with a properly organized national health system, aimed to record specific data from a significant number of patients with diabetes and documented stable CAD (SCAD). Methods and results: We conducted our survey across the country, in private and public primary, secondary, and tertiary care centers. A total of 1900 patients aged 71 ± 10 years old who suffered from both DM and chronic coronary syndromes were registered. Of the patients registered, 574 (30.24%) were women. It was found that 506 (26.6%) of the 1900 surveyed patients showed typical angina symptoms, while another 560 (29.5%) patients had developed angina-equivalent symptoms according to their history. Additionally, 324 (17%) patients had atypical symptoms that could not easily be attributed to existing CAD and the remaining 510 (26.8%) of the 1900 patients did not exhibit any angina symptoms during their daily activities. Functional testing for myocardial ischemia was not performed in 833 patients (43.8%). Myocardial scintigraphy was the most commonly used noninvasive technique (644 patients, 34%), while 492 patients (25.9%) had an exercise test and 159 (8.4%) underwent stress echocardiography. Conclusion: Real-world data in this specific high-risk population of diabetic patients with SCAD offer the opportunity to identify and improve diagnostic and therapeutic practice in the healthcare system of a European Union country.

Abstract Accurate risk stratification in COVID-19 patients consists a major clinical need to guide therapeutic strategies. We sought to evaluate the prognostic role of estimated pulse wave velocity (ePWV), a marker of arterial stiffness which reflects overall arterial integrity and aging, in risk stratification of hospitalized patients with COVID-19. This retrospective, longitudinal cohort study, analyzed a total population of 1671 subjects consisting of 737 hospitalized COVID-19 patients consecutively recruited from two tertiary centers (Newcastle cohort: n = 471 and Pisa cohort: n = 266) and a non-COVID control cohort (n = 934). Arterial stiffness was calculated using validated formulae for ePWV. ePWV progressively increased across the control group, COVID-19 survivors and deceased patients (adjusted mean increase per group 1.89 m/s, P

Abstract Background Significant sinus bradycardia (SB) in the context of sinus node dysfunction (SND) has been associated with neurological symptoms. The objective was to evaluate the effect of permanent pacing on the incidence of syncope in patients with rather mild degrees of SB, unexplained syncope, and “positive” invasive electrophysiologic testing. Methods This was an observational study based on a prospective registry of 122 consecutive mild SB patients (61.90 ± 18.28 years, 61.5% male, 57.88 ± 7.73 bpm) presenting with recurrent unexplained pre and syncope attacks admitted to our hospital for invasive electrophysiology study (EPS). Τhe implantation of a permanent antibradycardia pacemaker (ABP) was offered to all patients according to the results of the EPS. Eighty patients received the ABP, while 42 denied. Results The mean of reported syncope episodes was 2.23 ± 1.29 (or presyncope 2.36 ± 1.20) in the last 12 months before they were referred for a combined EP guided diagnostic and therapeutic approach. Over a mean follow‐up of approximately 4 years (50.39 ± 32.40 months), the primary outcome event (syncope) occurred in 18 of 122 patients (14.8%), 6 of 80 (7.5%) in the ABP group as compared to 12 of 42 (28.6%) in the no pacemaker group (P = .002). Conclusions Among patients with mild degree of SB and a history of unexplained syncope, a set of positivity criteria for the presence of EPS defined SND after differentiating reflex syncope, identifies a subset of patients who will benefit from permanent pacing.

Background: In randomized clinical trials, proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) effectively reduce low-density lipoprotein-cholesterol (LDL-C) with a favorable tolerability and safety profile. Our purpose is to provide real-world data regarding the indications, efficacy and safety of PCSK9i. Methods: The cohort comprised 141 patients who attended the lipid clinic of 3 hospitals in Greece and started using PCSK9i. Patients were requested to attend the lipid clinic at 3 months and at 1 year. Results: Ninety percent of patients had heterozygous familial hypercholesterolaemia (heFH) and 75% had cardiovascular disease (CVD). A PCSK9i [evolocumab 140 mg/2 weeks (n = 82), alirocumab 75 mg/2 weeks (n = 46) and alirocumab 150 mg/2 weeks (n = 13)] was prescribed due to failure to achieve LDL-C targets despite maximum lipid-lowering therapy (LLT) in 75% of patients, while in the remaining cases, the indication was statin intolerance. The mean reduction of LDL-C at 3 months was 56.2% and remained constant at 12 months (55.8% reduction from baseline). LDL-C target was achieved by 68.1% of patients at 3 months. “Totally” intolerant to statins patients (unable to tolerate any statin dose, n = 23) showed the lowest LDL-C reduction (47.7%). Side effects attributed to treatment were reported by 14 patients (10%). The total number of patients who stopped PCSK9i at 1 year was 14 (10%) but only 2 (1.4%) discontinued treatment because of side effects (myalgias). Conclusions: Our real-world results of PCSK9i showed comparable efficacy and tolerability to those reported in clinical trials and highlighted the value of treatment with PCSK9i heFH patients not achieving LDL-C targets despite maximum LLT and high or very high risk statin intolerant patients.

Accumulating evidence considers psoriasis a systemic inflammatory disorder that is associated with comorbidities such as psoriatic arthritis, cardiovascular disease, and metabolic syndrome. Although the precise pathogenetic links between psoriasis and atherosclerosis warrants further investigation, it is believed that chronic systemic inflammation along with the T helper (Th)-1 and Th17 polarization are associated with endothelial dysfunction and subsequent acceleration of atherosclerosis. Considering the above, several studies have evaluated if optimal control of the inflammation in psoriasis by inhibiting interleukins targeting the Interleukin (IL)-23/Th17 axis could subsequently reduce the atherosclerotic process during anti-psoriatic treatment by using a variety of surrogate markers of subclinical atherosclerosis. This systematic review summarizes current knowledge on the pathogenetic mechanisms and diagnostic evaluation of atherosclerosis in the context of psoriasis and provides a systematic review of the literature on the impact of treatment with biologics targeting the IL-23/Th17 axis on subclinical atherosclerosis in patients with plaque psoriasis and/or psoriatic arthritis.

Background: Cardiac magnetic resonance (CMR) combined with late gadolinium enhancement (LGE) has revealed a non-negligible increased incidence of myocardial fibrosis (MF) in athletes compared to healthy sedentary controls.Objective: The aim of this systematic research and meta-analysis is to investigate and present our perspective regarding CMR indices in athletes compared to sedentary controls, including T1 values, myocardial extracellular volume (ECV) and positive LGE indicative of non-specific fibrosis, also to discuss the differences between young and veteran athletes.Methods: The protocol included searching, up to October 2021, of MEDLINE, EMBASE, SPORTDiscus, Web of Science and Cochrane databases for original studies assessing fibrosis via CMR in athletes. A mean age of 40 years differentiated studies' athletic populations to veteran and young.Results: The research yielded 14 studies including in total 1,312 individuals. There was a statistically significant difference in LGE fibrosis between the 118/759 athletes and 16/553 controls (Z = 5.2, P < 0.001, I2 = 0%, PI = 0.45). Notably, LGE fibrosis differed significantly between 546 (14.6%) veteran and 140 (25.7%) young athletes (P = 0.002). At 1.5T, T1 values differed between 117 athletes and 48 controls (P < 0.0001). A statistically significant difference was also shown at 3T (110 athletes vs. 41 controls, P = 0.0004), as well as when pooling both 1.5T and 3T populations (P < 0.00001). Mean ECV showed no statistically significant difference between these groups.Conclusions: Based on currently available data, we reported that overall LGE based non-specific fibrosis and T1 values differ between athletes and sedentary controls, in contrast to ECV values. Age of athletes seems to have impact on the incidence of MF. Future prospective studies should focus on the investigation of the underlying pathophysiological mechanisms.

Arrhythmias in pericardial syndromes have been poorly investigated and available data are mainly obtained from relevant studies however having different endpoints from arrhythmias. Thus, the incidence and prevalence of any type of arrhythmias may be actually higher than generally considered. Atrial arrhythmias, mainly atrial fibrillation and flutter have been reported as the most common rhythm disturbances in the setting of acute pericarditis. Concerning pathophysiology of atrial arrhythmias, in contrast to earlier hypothesis that they occur exclusively in the presence of an underlying structural heart disease, recent data support an arrhythmogenic potential of acute pericardial inflammation regardless of the presence of heart disease. In cases of myopericarditis, namely primarily pericarditis with evidence of myocardial involvement (i.e., troponin elevation without however overt left ventricular dysfunction and/or segmental wall motion abnormalities), ventricular arrhythmias appear to prevail. With reference to the rest of pericardial syndromes data on arrhythmias development are even more sparce. In particular, in constrictive pericarditis atrial tachyarrhythmias are the most commonly detected and seem to be related to disease severity and possibly to the underlying etiology. In this review we have summarized the available information on the incidence and prevalence of arrhythmias in pericardial syndromes. We wish to emphasize that the clinical significance of arrhythmias in this setting in terms of prognosis and optimal medical treatment (including need and safety of anticoagulation in atrial fibrillation/flutter complicating acute pericarditis), should be further investigated.

Diseases of the circulatory (Cardiovascular) system ,RC666-701 - Abstract
Background: Aspirin and nonsteroidal anti-inflammatory drugs (A/NSAIDs) are the mainstay treatments for acute pericarditis. We sought to identify factors predicting failure of A/NSAIDs and switch to corticosteroid treatment (STCT) as well as the impact of STCT on pericarditis recurrence. Methods: We enrolled 148 patients with acute pericarditis receiving A/NSAIDs (n=110) or corticosteroids (n=38) as first-line treatment according to clinical indications. In case of poor response to A/NSAIDs (n=37), STCT was performed and factors contributing to such failure were explored. All patients were followed-up prospectively for 18 months for pericarditis recurrence. Results: In multivariate analysis, female sex (odds ratio [OR] =3.57, 95% confidence interval [CI]: 1.00-12.5), age (per decade, OR=0.75, 95% CI: 0.57-0.99), PR-segment depression (OR=4.43, 95% CI: 1.02-19.34), and a secondary cause of pericarditis (OR=13.52, 95% CI: 1.51-117.8) were independent predictors of poor response to A/NSAIDs and STCT. In cox regression analysis, the risk of recurrence was higher in patients requiring STCT (hazards ratio [HR] =3.22, 95% CI: 1.70-6.13) and in those initially treated with corticosteroids (H=2.06, 95% CI: 1.01-4.21) than in patients receiving A/NSAIDs only. Conclusions: Treatment failure with A/NSAIDs in acute pericarditis can be anticipated by certain patient characteristics. STCT identifies patients who are at the highest risk for recurrences, a risk that is approximately threefold higher than that of A/NSAIDs and 1.5-fold higher than that of corticosteroids as first-line treatment.

Diseases of the circulatory (Cardiovascular) system ,RC666-701 - Abstract
Objective: Proprotein convertase subtilisin/kexin type 9 (PCSK9) levels predict cardiovascular risk. We aimed to determine the correlation of PCSK9 levels with predictors of cardiovascular risk, such as central hemodynamics and carotid intima-media thickness (cIMT), in subjects with familial dyslipidemias. Methods: Thirty-three asymptomatic subjects (age: 45.4 ± 12.3 years, 21 men) with either familial combined hyperlipidemia or heterozygous familial hypercholesterolemia, free from hypolipidemic therapy, underwent evaluation for central hemodynamics (aortic augmentation index [AIx@75] and augmented pressure [AP]) and cIMT. PCSK9 levels were measured by ELISA. Results: In the univariate model, circulating PCSK9 levels were related to age (r = 0.351, P = 0.045), AP (r = 0.442, P = 0.011), AIx@75 (r = 0.463, P = 0.007), and cIMT (r = 0.559, P = 0.011). In multivariate analysis, significant positive associations of AP, AIx@75, and cIMT with PCSK9 levels were observed after adjusting for relevant confounders (P = 0.018, P = 0.002, and P = 0.011, respectively). Patients with both high cIMT (>0.81 mm) and high AIx@75 (>20%) had significantly increased PCSK9 levels compared with subjects with both low cIMT and low AIx@75 (316 ng/ml vs. 155 ng/ml, P = 0.037). Conclusions: In familial dyslipidemias, PCSK9 levels are positively associated with predictors of cardiovascular risk, such as central hemodynamics and cIMT. These relationships may aid in the stratification of cardiovascular risk by identifying a high-risk subgroup within these entities.

Diseases of the circulatory (Cardiovascular) system ,RC666-701 - Abstract
Smoking during pregnancy is a risk factor associated with adverse pregnancy outcomes. Despite the fact that these outcomes are well known, a considerable proportion of pregnant women continue to smoke during this critical period. This paper evaluates critically smoking cessation interventions targeting pregnant women. We describe the findings of key published studies, review papers and expert statements to report the efficacy and safety of strategies for smoking cessation in pregnancy, including counselling and pharmacotherapy. Counselling appears to improve quit rates but mainly when used in combination with pharmacological therapy. Pharmacotherapy is recommended for women who are heavy smokers and are unable to quit smoking on their own. Nicotine replacement therapy is a reasonable first-line drug option. It is recommended that women who are pregnant, or planning to become pregnant, should be informed of potential risks for the foetus before considering smoking cessation therapy with bupropion or varenicline. Pregnant women view electronic nicotine delivery systems as being safer than combustible cigarettes, and this indeed may be the case; however, further evidence is required to assess their effectiveness as a smoking cessation aid and their safety for the mother and the child. Postpartum relapse is a significant problem, with approximately one out of two quitters relapsing in the first 2 months after delivery. These women should be considered ‘at risk’ and provided with ongoing support. Keywords: Pregnancy, Smoking, Smoking cessation, Counselling, Pharmacotherapy

Neurology. Diseases of the nervous system ,RC346-429 - Abstract
Neurological manifestations are not uncommon during infection with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A clear association has been reported between cerebrovascular disease and coronavirus disease 2019 (COVID-19). However, whether this association is causal or incidental is still unknown. In this narrative review, we sought to present the possible pathophysiological mechanisms linking COVID-19 and cerebrovascular disease, describe the stroke syndromes and their prognosis and discuss several clinical, radiological, and laboratory characteristics that may aid in the prompt recognition of cerebrovascular disease during COVID-19. A systematic literature search was conducted, and relevant information was abstracted. Angiotensin-converting enzyme-2 receptor dysregulation, uncontrollable immune reaction and inflammation, coagulopathy, COVID-19-associated cardiac injury with subsequent cardio-embolism, complications due to critical illness and prolonged hospitalization can all contribute as potential etiopathogenic mechanisms leading to diverse cerebrovascular clinical manifestations. Acute ischemic stroke, intracerebral hemorrhage, and cerebral venous sinus thrombosis have been described in case reports and cohorts of COVID-19 patients with a prevalence ranging between 0.5% and 5%. SARS-CoV-2-positive stroke patients have higher mortality rates, worse functional outcomes at discharge and longer duration of hospitalization as compared with SARS-CoV-2-negative stroke patients in different cohort studies. Specific demographic, clinical, laboratory and radiological characteristics may be used as ‘red flags’ to alarm clinicians in recognizing COVID-19-related stroke.

Introduction: Malignancies are the second leading cause of death worldwide. Treatment Monoclonal Antibody (MAbs)-based treatment of cancer has been established as one of the most successful therapeutic strategies in the last 20 years; however, there is a growing concern about the effects of these agents on patients’ cardiovascular profile. Areas Covered: In this manuscript we summarize current evidence regarding MAb effects on arterial stiffness, which is an recognised biomarker of cardiovascular risk. For this purpose, we explored two bibliographic databases [PubMed, Scopus] and one full-text database (Google-Scholar) for all publications published on MAbs’ effects on arterial stiffness until December 2019. Only few of the monoclonal antibody agents used in oncology have been investigated as per their effects on arterial properties and this limited evidence suggests that cancer therapy with monoclonal antibodies demonstrates either a temporary or long-term increase in arterial stiffness. Discussion: It seems that by targeting ‘checkpoints’ in cancer genesis, anticancer MAbs also affects vascular properties causing endothelial dysfunction and arterial stiffness. Furthermore, several MAbs cause hypertension and may as a result increase pulse wave velocity. On the other hand, MAbs that target inflammatory cytokines seem to improve cardiovascular survival however, their effect on arterial stiffness is yet to be investigated. Further research is warranted in order to elucidate the biochemical pathways, clinical implications and potential reversibility of monoclonal antibody chemotherapy-induced vascular dysfunction.

Abstract Purpose/Background/Objectives Acute kidney injury (AKI) is a serious postoperative complication. Increased arterial stiffness has been shown to be an independent risk factor for cardiovascular events. Our aim was to investigate whether arterial stiffness is a predictor of AKI in patients following surgical aortic valve replacement (SAVR). Methods Eighty-four patients (mean age 72 ± 8 years, 34 females) with moderate to severe aortic stenosis undergoing SAVR were included. As indicators of arterial stiffness aortic hemodynamics, carotid-femoral pulse wave velocity (cfPWV) and brachial-ankle pulse wave velocity (baPWV) were assessed prior to surgery. Renal dysfunction was defined when eGFR was below 60 ml/min (n = 28, 33%). AKI was defined using KDIQO criteria. Results Twelve patients (14%) developed AKI. There was no significant difference in aortic hemodynamics and cfPWV between the two groups. baPWV significantly correlated with AKI (r = 0.313, p = 0.004). In logistic regression analysis, increase of baPWV per 1 Standard Deviation (Odds Ratio [OR] = 2.76, 95% Confidence intervals [CI]: 1.25–6.11, p = 0.012) and presence of renal dysfunction (OR = 14.93, 95% CI: 2.55–87.32, p = 0.003) were associated with higher risk for AKI even after adjustment for age, gender, systolic blood pressure and diabetes. baPWV was a stronger predictor of AKI than baseline creatinine (Area under the curve [AUC] 0.68, 95% CI: 0.52–0.84, p = 0.05 vs AUC 0.61, 95% CI: 0.46–0.77, p = 0.21; p < 0.05). Conclusion baPWV could be considered as a useful predictive biomarker for AKI after SAVR, especially in patients with renal dysfunction prior to surgery.

Purpose /Background /Objectives: Vitamin K antagonists (VKA) aggravate vascular calcifications burden, especially in haemodialysis patients potentially compounding their cardiovascular risk. We sought to investigate the relationship between VKA intake and aortic arch calcification (AAC) in patients with acute coronary syndrome (ACS). Methods: Two hundred patients admitted with ACS were included in the study (mean age 66 ± 15 years). The extent of aortic arch calcification (AAC) on a postero-anterior plain chest X-ray was divided into four grades (0 to 3). Grades 0 to 1 and grades 2 to 3 were categorized as lower and higher AAC grade respectively. Anticoagulants were categorized to VKA and to non-VKA anticoagulants including new oral anticoagulants and low-molecular weight heparin. Results: Twenty-eight (14%) patients at admission were on anticoagulants. Seventeen patients (8.5%) were treated with VKA and 12 patients (6%) with non-VKA anticoagulants. Higher ACC grade was observed in patients treated with VKA after adjustment for age, gender and chronic kidney disease. (Odds ratio [OR] = 3.64, 95% Confidence intervals [CI]: 1.08 to 12.20, p = 0.037). Interestingly, there was a non-statistically significant trend for reduced risk of higher AAC grade in patients treated with non-VKA anticoagulants (OR = 0.24, 95% CI: 0.04 to 1.47, p = 0.12). Age and history of chronic kidney disease were the most potent predictors of higher AAC grade (OR = 1.07, 95% CI: 1.03 to 1.10, p < 0.001 and OR = 6.07, 95% CI: 2.35 to 15.67, p < 0.001, respectively). Conclusion: Our study shows intake of VKA is associated with higher risk of AAC in ACS patients, while non-VKA anticoagulants might be associated lower AAC grade.

Purpose/Background/Objectives: Aortic stiffness and hemodynamics are independent predictors of adverse cardiovascular events. Transcatheter aortic valve implantation (TAVI) is growingly used in high surgical risk patients with aortic valve stenosis. We sought to investigate the effect of TAVI on aortic stiffness. Methods: Fifty-five high-risk patients (mean age 79.5 ± 8.8 years, 46% males) with severe symptomatic aortic stenosis undergoing TAVI were included. Arterial stiffness was estimated through carotid-femoral pulse wave velocity (cfPWV). Measurements were conducted prior to the implantation, at discharge and 1 year post-TAVI. Results: Prior to the implantation, cfPWV was 7.5 ± 1.4 m/s for the overall population. There was a statistically significant increase in measurements of aortic stiffness at discharge (7.5 ± 1.4 vs 8.3 ± 1.9 m/s for cfPWV with p = 0.043) without a statistically significant change in SBP (p = NS) (Figure 1). There was also a significant increase in cfPWV (8.7 ± 1.8 m/s) after 1 year compared to the pre-procedural assessment (p = 0.001). We also observed a non-significant increase in peripheral SBP at 1 year compared to SBP measurements at baseline and at discharge (153 ± 24 m/s vs 147 ± 21and 148 ± 22 m/s, respectively; p = 0.319) and these changes were independent of age and gender (Figure 1). Conclusion: Our study shows that both shortly as well as in the long-term after TAVI subjects experience an increase in aortic stiffness that is independent of changes in SBP. These findings further elucidate the hemodynamic consequences and provide evidence of a possible long-standing repercussion of TAVI. Figure 1

Purpose/Background/Objectives: Cardiac autonomic dysfunction is associated with increased cardiovascular mortality and arrhythmias. The aim of the study was to investigate the effect of heart rate variability (HRV) in the prognosis of future arrhythmic events. Methods: We studied 292 untreated at baseline hypertensives (mean age 53 ± 13, 153 males). Cardiac autonomic function was evaluated by analysis of short-term HRV using 24-h ambulatory blood pressure monitoring and the standard deviation of measurements. Left ventricular mass index (LVMI) was estimated echocardiographically. Aortic stiffness was assessed with carotid-femoral pulse wave velocity (cfPWV) and aortic augmentation index corrected for heart rate (AIx@75). Patients were followed up for 13 years. The primary endpoint was a composite of atrial/ventricular tachycardias, symptomatic multiple premature ventricular contractions, second and third-degree heart blocks and pacemaker/defibrillator placement. Results: Patients with the primary endpoint (n = 37.13%) had lower 24-h daytime HRV (9.6 beats per minute vs 11.1 beats per minute, p = 0.005), higher systolic blood pressure (168 mmHg vs 163 mmHg, p = 0.003), higher cfPWV (8.4 m/s vs 7.7 m/s, p = 0.005), higher LVMI (133 g/m2 vs 122 g/m2, p = 0.002) and higher AIx@75 (29.0% vs 26.3%, p = 0.043) compared to patients with no events. In Cox regression analysis, only higher HRV was associated with lower risk of arrhythmic events (Hazard ratio per 1 mmHg = 0.87, 95% Confidence intervals 0.76 to 0.995, p = 0.043) when adjusted for age, gender, cfPWV, LVMI and AIx@75. Conclusion: Lower heart rate variability is associated with increased risk of future arrhythmic events suggesting an early sympathovagal imbalance that could lead to future events.

Purpose/Background/Objectives: Hypertension is associated with increased cardiovascular risk, inflammation and arterial stiffness. We sought to investigate the role of inflammation and arterial stiffness in the prognosis of cardiovascular hospitalization in hypertensives patients over an extensive follow-up. Methods: One hundred and seventy-three patients (mean age 52.5 ± 13.2 years, 57% males) untreated hypertensives at baseline without cardiovascular disease, were included in the study. Arterial stiffness was assessed with carotid-femoral pulse wave velocity (PWV). High-sensitivity C-reactive protein (hsCRP) was measured in venous blood samples. Results: During 13.6 ± 0.4 years of follow-up, forty-four patients (25.4%) patients were admitted in hospital due to cardiovascular causes. In multivariable logistic regression analysis, only higher hsCRP (Odds Ratio [OR] = 3.34, 95% Confidence intervals [CI]: 1.22–9.51, p = 0.020) and increased PWV (OR = 1.48, 95% Confidence intervals [CI]: 1.03–2.12, p = 0.036) were associated with higher risk of cardiovascular hospitalizations, which was independent of age, gender, systolic blood pressure, left ventricular mass index and presence of diabetes. In further analysis, receiver operating characteristic (ROC) curves were generated to evaluate the ability of hsCRP and PWV to discriminate subjects with cardiovascular hospitalization. The area under the curve (AUC) and 95% CIs of the ROC curves were AUC = 0.69 (95% CI: 0.59–0.78, p < 0.001) for hsCRP and AUC = 0.74 (95% CI: 0.65–0.83, p < 0.001) for PWV (Figure 1). Figure 1Diagonal segments are produced by ties. Conclusion: Our study shows the independent complimentary prognostic role of inflammation and arterial stiffness in the prognosis of hypertensives even in studies with extensive follow-up.

Background We compared the acute and midterm effect of ticagrelor versus clopidogrel on aortic stiffness. Methods and Results We studied 117 patients in a randomized, assessor‐blinded, parallel‐group trial. The acute effect of ticagrelor was studied in 58 patients randomized (1:1) to receive a loading dose of clopidogrel (600 mg) or ticagrelor (180 mg). Carotid‐femoral pulse wave velocity (cfPWV) was measured before, 3, and 24 hours after the loading dose. The midterm effect (30‐day treatment period) was studied in 59 subjects who underwent percutaneous coronary intervention and were randomized to either clopidogrel (75 mg, OD) or ticagrelor (90 mg BID). cfPWV was measured before and at 30 days of treatment. Circulating markers of inflammation and endothelial function were measured at all study points. Repeated‐measures analysis showed a significant main effect for treatment (P=0.03), with the ticagrelor showing a reduction in cfPWV after treatment. cfPWV at 24 hours was significantly lower in the ticagrelor group compared with the clopidogrel group (P=0.017) (maximal response reduction by 0.42±0.26 m/s). At 30 days, cfPWV decreased in the ticagrelor group, whereas there was no change with clopidogrel (−0.43±0.57 versus 0.12±0.14 m/s, P=0.004). There were no significant changes in both the acute and midterm study period in the pro‐inflammatory and endothelial function parameters. Conclusions URL: https://www.clinicaltrials.gov. Unique identifier: NCT02071212. Ticagrelor decreases cfPWV for 24 hours after the loading dose and at 1 month post–percutaneous coronary intervention compared with clopidogrel. Considering that aortic stiffness is an independent predictor of cardiovascular events, this finding may have clinical implications regarding the beneficial effect of ticagrelor. Clinical Trial Registration URL: http://www.clinicaltrials.gov. Unique identifier: NCT02071212.

Type 2 diabetes mellitus affects nearly four hundred million people worldwide, and one of its major complications is cardiovascular disease. The evaluation of the effectiveness and safety of antidiabetic medication has been a challenging issue. Large clinical trials of new antidiabetic medications have used the non-inferiority approach to ensure primary safety of the drug before its incorporation into clinical practice. Currently, the trend is to prove superiority, that is, to prove that the new drug has additional beneficial effects to those of standard medications. In this review, we present the results of recent clinical trials on type 2 diabetes mellitus medications and outline what can be anticipated from ongoing clinical trials.

Purpose/Background/Objectives: Aortic stiffness assessed by carotid-femoral pulse wave velocity (PWV) is an important predictor to gauge the overall risk of hypertensive patients; nonetheless, it is underutilized in everyday practice. We derived a simple scoring system based on clinical variables that can identify patients with a priority for measurement of PWV, i.e. those with elevated PWV (≥ 10 m/sec) and at higher risk for events. Methods: Patient data from three outpatient clinics (n = 3,943) were used to form a derivation, internal and external validation cohort. For derivation, independent predictors of high PWV from a binary logistic regression model were dichotomized and implemented in a clinical prediction scoring system with the acronym SAGE (office systolic blood pressure ≥160 mmHg: 4 points, age ≥ 60 years: 4 points, glycemia [blood glucose ≥126 mg/dl]: 1 point, eGFR ≤60: 2 points). Results: Its performance was validated at the internal and external validation cohorts with c-statistics being 0.781 (95% CI: 0.753–0.808) and 0.718 (95% CI: 0.682–0.755) respectively (Figure 1). A cut-off of 5 points to identify patients with high PWV in the external validation cohort yielded a positive predictive value, negative predictive value, sensitivity and specificity of 60.7%, 84.8%, 51.9% and 78.3% respectively. Conclusions: The SAGE score that takes into account easily measured clinical variables (systolic blood pressure, age, glucose and eGFR) can be used to predict elevated levels of PWV and prioritize its measurement in specific patients. Its use will result in greater acknowledgement of the role of aortic stiffness and aid physicians in implementing it in clinical practice.

Purpose/Background/Objectives: Aortic calcifications and inflammation are independent predictors of adverse cardiovascular events. We sought to investigate the association of aortic calcifications and inflammation with in-hospital morbidity and mortality of patients with acute coronary syndrome (ACS). Methods: Two hundred patients (mean age 66 ± 15 years, 150 males) admitted to our Hospital with ACS from 2016-2017 were included in the study. The extent of aortic arch calcification (AAC) on a postero-anterior plain chest X-ray was divided into four grades (0 to 3). Grades 0 to 1 and grades 2 to 3 were categorized as lower and higher AAC grade respectively. High-sensitivity C-reactive protein (hsCRP) was also assessed. In-hospital complications that included reinfarction, arrhythmias, heart failure, stroke, mechanical complications, renal failure, surgery and death were assessed in all patients. Results: The majority of patients (n = 132, 66%) presented with non-ST elevation ACS, whereas 68 patients as ST-elevation myocardial infarction (STEMI) (n = 68, 34%). Seventy-seven (38.5%) patients presented with one or more in-hospital complications (6 of them died). Higher AAC grade was visible in 44 patients (22%). Patients with higher AAC had increased risk (Odds ratio [OR] = 2.29, 95% Confidence intervals [CI] 1.03 to 5.12, p = 0.043) for in hospital complications after adjusting for age, gender, STEMI/NSTE-ACS diagnosis (OR = 4.10, 95% CI 2.08 to 8.05 for STEMI diagnosis, p < 0.001) and hsCRP (OR = 1.80, 95% CI 1.10 to 2.93, p = 0.02). Conclusions: Our study shows that simple tools can be used to assess the in-hospital risk of ACS patients. It also highlights the prognostic role of arterial stiffness and low-grade inflammation in ACS.

Purpose/Background/Objective: Arterial stiffness and aortic hemodynamics are independent predictors of adverse cardiovascular events. Indications for Transcatheter Aortic Valve Implantation (TAVI) are increasing in number and Aortic Valve Calcifications (AVC) are an important prognostic factor of TAVI. We sought to investigate the associations between AVC and aortic vascular function/hemodynamics. Methods: Fifty-two high-risk patients (mean age 80.4 ± 8.5 years, 27 male) with severe symptomatic aortic stenosis undergoing TAVI were included. Arterial stiffness was estimated through carotid-femoral pulse wave velocity (cfPWV) and brachial-ankle pulse wave velocity (baPWV). Aortic hemodynamics were also measured. Measurements were conducted prior to the implantation and at discharge. In all patients, a native and contrast-enhanced multislice cardiac computed tomography were performed pre-interventionally. AVC were then graded semi-quantitatively. Results: Group 1 (subjects with none/mild AVC, n = 29) did not significantly differ on age, gender and body-mass index compared to group 2 (subjects with moderate/severe AVC, n = 23). From the traditional cardiovascular risk factors, only hypertension (p = 0.008), coronary artery disease (p = 0.016), atrial fibrillation (p = 0.075) and insulin-dependent diabetes mellitus (p = 0.068) were more statistically or showed a significant trend to be more prevalent in group 2. Group 2 had significantly higher both cfPWV and baPWV (8.3 ± 1.7 vs 7.2 ± 1.2 m/s and 1750 ± 484 cm/s vs. 2101 ± 590 cm/s with p = 0.008 and p = 0.022 respectively) compared to Group 1. (Figure) There was no difference in wave reflections indices between the two groups. Conclusions: Our study shows that in patients with aortic stenosis there is a correlation between an increase in aortic stiffness and damage of aortic valvular leaflets as well as calcifications.

Purpose/Background/Objectives: Aortic stiffness and hemodynamics are established biomarkers for cardiovascular events. Surgical aortic valve replacement (SAVR) remains the first choice of treatment in most patients with aortic stenosis. We investigated the effect of SAVR on aortic stiffness and the role of arterial biomarkers in predicting the echocardiographic respons. Methods: We included thirty-three patients (mean age 71 ± 8 years, 58% males) with moderate to severe aortic stenosis undergoing SAVR. In measurements prior and acutely after the surgery, carotid-femoral pulse wave velocity (cfPWV) and brachial-ankle pulse wave velocity (baPWV) and aortic hemodynamics (aortic augmentation index corrected for heart rate [AIx@75]) were used as indicators of arterial stiffness. Echocardiography, mean and peak pressure gradient of the aortic valve was measured and their differences post and pre-surgery were calculated (i.e. ΔMeanGradient = MeanGradient post-surgery−MeanGradient pre-surgery). Results: There was a statistically significant increase on measurements of aortic stiffness (7.5 ± 1.4 vs 8.2 ± 1.9 m/s for cfPWV, p = 0.033) and a decrease in wave reflections (28 ± 13% vs 21 ± 11% for AIx@75, p = 0.015). We also observed a negative association of baseline cfPWV with baseline mean and peak gradient of aortic stenosis (r=−0.598 and r=−0.614 with p = 0.002 and p = 0.001, respectively), independently of age, gender and systolic blood pressure. Baseline cfPWV was associated with ΔMeanGradient and ΔPeakGradient (r = 0.609 and r = 0.533 with p = 0.002 and p = 0.009, respectively). (Figure) Conclusions: Our study shows that post-operative aortic stiffness increases while there is an improvement of wave reflections. Furthermore, increased aortic stiffness prior to surgery predicts smaller benefit in decreasing transvalvular pressure gradient as assessed echocardiographically, implying that low aortic stiffness prior to surgery could lead to better outcome.

Background: Microwave Radiometry (MWR) is a new validated method, which allows evaluation of thermal heterogeneity of carotid arteries and is associated with inflammation.Purpose: The aim of this pilot study was to determine if thermal heterogeneity in the carotid arteries is associated with aortic elastic properties in patients with dyslipidemia and whether treatment for dyslipidemia affects thermal heterogeneity. Method: Twenty-nine patients with dyslipidemia (mean age 42 ± 13 years, range 22–75, 19 men) without known cardiovascular disease, underwent assessment of carotid thermal heterogeneity (temperature difference-ΔT) using MWR. Mean common carotid intima-media thickness (CIMT) was also assessed. Twenty-one patients were treated for 6 months with statin or/and ezetimibe and thermal heterogeneity was assessed after treatment. Results: There was a positive correlation between ΔT and cIMT (r = 0.474, p = 0.009). In multivariate regression analysis, after adjustment for potential confounders such as age, sex, mean blood pressure and body-mass index, cIMT showed a positive correlation with ΔT in carotid arteries (Adjusted R2 = 0.258, p = 0.048). Thermal heterogeneity after 6 months of treatment was reduced statistically significant (0.88 ± 0.42 to 0.58 ± 0.29 °C, p = 0.021) (Image). Conclusion: In a group of patients with dyslipidemia thermal heterogeneity in the carotid arteries was positively associated with carotid subclinical atherosclerosis. Moreover, dyslipidemia treatment reduced thermal heterogeneity after a short-term period, implying a beneficial effect of treatment on thermal heterogeneity.

Erectile dysfunction (ED) has been found to frequently precedes the onset of coronary artery disease (CAD), representing an early marker of subclinical vascular disease, included CAD. Its recognition is, therefore, a "window opportunity" to prevent a coronary event by aggressive treatment of cardiovascular risk factors. The artery size hypothesis (ASH) has been proposed as a putative mechanism to explain the relationship between ED and CAD. Since atherosclerosis is a systemic disorder all major vascular beds should be affected to the same extent. However, symptoms at different points in the system rarely become evident at the same time. This is likely the result of smaller vessels (i.e. the penile artery) being able to less well tolerate the same amount of plaque when compared with larger ones (i.e. the coronary artery). If true, ED will develop before CAD. We present a case in which ED developed after a coronary event yet before a coronary recurrence potentially representing a late marker of vascular progression. Reasons for this unusual sequence are discussed as they might still fit the ASH.
