Objective: To analyze the prevalence of no-reflow and the 30-day mortality in a university center in a middle-income country. Method: We analyzed 2463 patients who underwent primary PCI from January 2006 to December 2021. The outcome measure was 30-day mortality. Results: Of a total of 2463 patients, no-reflow phenomenon was found in 413 (16.8%) patients, 30-day mortality was 16.7 vs. 4.29% (p < 0.001). Patients with no-reflow were older 60 (53-69.5) vs. 59 (51-66) (p = 0.001), with a higher delay in onset of symptom to emergency department arrival 270 vs. 247 min (p = 0.001). No-reflow patients also had had fewer previous myocardial infarction, 11.6 vs. 18.4 (p = 0.001) and a Killip class 1, 37 vs. 26% (p < 0.001). No-reflow patients were more likely to have an anterior myocardial infarction (55.4 vs. 47.8%; p = 0.005) and initial TIMI flow 0 (76 vs. 68%; p < 0.001). Conclusion: No-reflow occurred in 16.8% of STEMI patients undergoing primary PCI and was more likely with older age, delayed presentation, anterior myocardial infarction and Killip class > 1. No-reflow was associated with a higher mortality at 30-day follow-up. [ABSTRACT FROM AUTHOR]

Objective: To assess the association between coronary collateral circulation and ventricular contractile function in patients with non-reperfused acute myocardial infarction. Method: A retrospective and descriptive clinical study was conducted on patients with ST-elevation myocardial infarction (STEMI) at a reference cardiovascular center, from January 2006 to December 2022. Coronary angiographies and echocardiograms were reviewed to evaluate coronary collateral circulation and ventricular function, respectively. Patients were divided into groups based on the presence of collateral circulation. Both groups were compared and mortality during the index hospitalization was analyzed. Results: Out of a total of 14,985 patients with acute coronary syndrome, 8134 (54.3%) had the diagnosis of STEMI. We excluded 12,880, leaving a total of 2105 non-reperfused STEMI patients who underwent coronary angiography, revealing lesions. There were more patients without collateral circulation: 1547 (73.5%) vs. 558 (26.5%) (p = 0.025). Patients without collateral circulation had a higher left ventricular ejection fraction (median of 47% vs. 42%; p < 0.001). Mortality in patients with collateral circulation was higher compared to those without it (11.6% vs. 9.8%; p = 0.225), but statistical significance was not reached. Conclusions: Non-reperfused STEMI patients did not show protection from collateral circulation when assessing left ventricular systolic function. We did not find a difference in mortality compared to the population without development of collateral circulation. [ABSTRACT FROM AUTHOR]

Introduction. Paradoxical embolism is a thrombotic event originating in the venous circulation, which manifests as arterial embolism through an anatomical cardiac or pulmonary defect. It is mainly associated with stroke, also presenting as acute myocardial infarction, renal infarction, and other ischemic events. Clinical case. A 47-year-old patient was admitted due to abdominal pain, which required emergency surgical management, finding significant intestinal ischemia. Additional studies found protein S deficiency and evidence of a patent foramen ovale. Discussion. Arterial thrombosis is known as unusual thrombosis; this situation requires to rule out associated thrombophilia or other prothrombotic diseases. Protein S deficiency is a rare thrombophilia, which in adults causes venous thrombosis. In the presence of anatomical defects, such as a patent foramen ovale, it can progress to arterial embolism, presenting a picture of paradoxical embolism. The study work of these patients requires imaging that demonstrates the aforementioned defect, as well as the possible origin of the emboli. Management is based on full anticoagulation, treatment of existing thrombotic manifestations, and management of the anatomical defect. Conclusions. Paradoxical embolism should be suspected in case of unusual thrombosis. It requires exhaustive studies based on imaging, and management should consist of anticoagulation and closure of the defect.

Objective: To identify the risk factors based on clinical, echocardiographic and therapeutic parameters which predict the development of cardiac complications among patients with diabetes and acute myocardial infarction (AMI). Materials and methods: An observational, analytical, case-control study was conducted at Centro de Cardiología y Cirugía Cardiovascular de Santiago de Cuba, attached to Hospital Provincial Saturnino Lora, from 2019 to 2021. The sample consisted of 266 patients, chosen by simple random sampling 1:2. The study included demographic, clinical- echocardiographic and therapeutic variables. A multivariate analysis was performed with all the variables considered as risk factors; one-way analysis of variance and binary logistic regression were used. Results: The most frequent cardiac complications were atrial fibrillation and heart failure (approximately 12 %). A metabolic control analysis on admission yielded altered results (OR = 6.92; LI: 2.61; LS: 18.32; p = 0.001). The univariate analysis showed that ten factors increased the risk of complications, including the diagnosis of diabetes mellitus ≥ 10 years (OR = 2.50; LI: 1.14; LS: 5.45; p = 0.020). On the other hand, the multivariate analysis revealed six factors that predict the development of cardiac complications: age ≥ 60 years (OR = 5.624; CI = 1.607-19.686; p = 0.007), altered metabolic control on admission (OR = 5.245; CI = 1.491-18.447; p = 0.010), lack of use of thrombolytic therapy (OR = 5.74; CI = 1.46-22.586; p = 0.012), left ventricular ejection fraction (LVEF) ≤ 40 % (OR = 5.245; CI = 1.17-23.433; p = 0.030), left atrial pressure ≥ 15 mmHg (OR = 12.335; CI = 3.45-44.08; p = 0.001) and motility ≥ 1.5 points (OR = 4.702; CI = 1.258-17.575; p = 0.021). Conclusions: The study demonstrated the value of six risk factors of cardiac complications among patients with diabetes and AMI, where glycemic control on admission, decreased LVEF, increased left atrial pressure and no reperfusion therapy stand out.

Inflammation is an important pathogenic factor for the development of atherosclerotic cardiovascular disease. Currently, the most frequently used biomarker reflecting systemic inflammation is C-reactive protein (CRP), an acute-phase protein produced primarily by hepatocytes under the influence of interleukin-6, interleukin-1 beta, and tumor necrosis factor. Growing evidence from epidemiological studies has shown a robust association between elevated serum or plasma CRP concentrations and the incidence of a first cardiovascular adverse event (including acute myocardial infarction, ischemic stroke, and sudden cardiac death) in the general population, as well as recurrence of major adverse cardiovascular events among patients with established disease. The additive value that CRP measurement gives to traditional risk factors is reflected in novel cardiovascular risk calculators and in current intervention regimens, which already consider CRP as a target therapeutic. However, the variations in CRP levels, that depend on sex, ethnicity, hormonal status, and some peculiarities of the measurement assays, must be taken into consideration when deciding to implement CRP as a useful biomarker in the study and treatment of atherosclerotic cardiovascular disease. This review aims to offer an updated vision of the importance of measuring CRP levels as a biomarker of cardiovascular risk beyond the traditional factors that estimate the risk of atherosclerotic disease.

The treatment of ST-segment elevation myocardial infarction has barriers depending on the geographic region. Primary coronary angioplasty is the treatment of choice, if it is performed on time and by experienced operators. However, when it is not available, the administration of fibrinolysis and referral for rescue angioplasty, in case of negative reperfusion, is the best strategy. n the same way, coronary angioplasty, as part of a pharmacoinvasive strategy, is the best alternative when there is positive reperfusion. The development of infarct treatment networks increases the number of patients reperfused within the recommended times and improves outcomes. In Latin America, national myocardial infarction treatment programs should focus on improving outcomes, and long-term success depends on working toward defined goals and enhancing functionality, therefore programs should develop capacity to measure their performance. The following document discusses all of these alternatives and suggests opportunities for improvement. [ABSTRACT FROM AUTHOR]

Background: The debate on percutaneous coronary intervention (PCI) of the unprotected left main coronary artery (LMCA) has been constant over time. Objective: To investigate the clinical and procedural characteristics and cardiovascular outcomes of PCI of unprotected LMCA. Material and methods: Observational study which included patients with unprotected LMCA disease undergoing PCI; patients with cardiogenic shock prior to the procedure were excluded. We describe the clinical and angiographic characteristics, as well as the major adverse cardiac and cerebrovascular events (MACCE) according to the year of the procedure. Results: We included 73 patients, with a SYNTAX I score of 31.2 ± 9.1, mostly with ST-elevation acute coronary syndrome (35%). There was a higher frequency of triple vessel coronary disease (63%) and distal LMCA lesions (35%). The provisional stent technique was the most used for distal lesions (58%) and the 2-stent technique for bifurcation lesions (78%), supported by intravascular ultrasound (IVUS) in 38%. During follow-up, 19 presented MACCE (26%), out of which cardiac death occurred in 13%, non-cardiovascular death in 5%, non-fatal acute myocardial infarction in 1%, cerebrovascular event in 2%, and revascularization of the treated vessel in 4%. Conclusions: It was observed a similar frequency to the one appearing in other studies of cardiovascular events, mainly in patients with intermediate risk, which supports the increasing use of percutaneous intervention in this population.

The right ventricle is susceptible to changes in preload, afterload, and contractility. The answer is its dilation with dysfunction/ acute failure; filling is limited to the left ventricle and cardiac output. Systemic venous congestion is retrograde to the right heart, it is involved in the genesis of cardiogenic shock due to right ventricle involvement. This form of shock is less well known than that which occurs due to left ventricular failure, therefore, treatment may differ. Once the primary treatment has been carried out, since no response is obtained, supportive treatment aimed at ventricular pathophysiology will be the next option. It is suggested to evaluate the preload for the reasoned indication of liquids, diuretics or even ultrafiltration. Restore or maintain heart rate and sinus rhythm, treat symptomatic bradycardia, arrhythmias that make patients unstable, use of temporary pacing or cardioversion procedures. Improving contractility and vasomotility, using vasopressors and inotropes, alone or in combination, the objective will be to improve right coronary perfusion pressure. Balance the effect of drugs and maneuvers on preload and/or afterload, such as mechanical ventilation, atrial septostomy and pulmonary vasodilators. And the increasing utility of mechanical support of the circulation that has become a useful tool to preserve/restore right heart function. [ABSTRACT FROM AUTHOR]

Introduction: Alterations in glycemic control and lipids are the main causes of cardiovascular disease. However, metabolic patterns in acute myocardial infarction are not well established. Objective: The purpose of this research is to describe the metabolic characteristics of patients admitted with myocardial infarction. We classified patients according to HDL-c/LDL-c ratio and lipid profiles. Method: observational, descriptive, retrospective study in patients admitted to the Cardiology Department with acute myocardial infarction for one year. Results: 97 patients were included, males predominated (67%) and the mean age was 59 years (SD, ±9.9). Metabolic characteristics were as follows: median glycosylated hemoglobin 6.2% (IQR, 5.8-7.5), fasting blood glucose 107 mg/dL (IQR, 99-152), total cholesterol 201 mg/dL (IQR, 165-223), low-density lipoprotein cholesterol (LDL-c) 123 mg/dL (IQR, 96-146), high-density lipoprotein-associated cholesterol (HDL-c) 38.2 mg/dL (IQR, 31.8-45.4) and triglycerides (TG) 161 mg/dL (IQR, 103-234). The HDL-c/LDL-c ratio <0.4 was present in 75% of patients. Patients were classified according to lipid profiles, where the L-1 HDL-c ≤ 40, LDL-c <150, TG <200] and L-2 ]HDL-c >40, LDL-c <150, TG <200] together represented half of the sample. Conclusions: prediabetes, low HDL-c levels, and an HDL-c/LDL-c ratio <0.4 were frequent findings in myocardial infarction. The relationship between metabolic patterns and the risk of myocardial infarction should be investigated. [ABSTRACT FROM AUTHOR]

Since the discovery of right ventricular infarction, interest in the characteristics of the right ventricle has been increasing. Right ventricular function is now known to be a predictor of mortality in different settings. The right ventricle is a low-pressure, high-compliance, high-volume chamber. To carry out its normal function, it is coupled to the pulmonary circulation and the left ventricle. In the face of acute changes in pressure, volume overload and ischemia, it dilates to adapt to its new load. Its manifestation may be ventricular dysfunction and/ or failure that will progress to cardiogenic shock due to right ventricular involvement. Various entities may be the cause of acute dysfunction: right ventricular infarction (alterations in contractility due to ischemia) and high-risk pulmonary thromboembolism (increased afterload). Both share a similar ventricular pathophysiology and high mortality without treatment. Understanding anatomy and physiology, dysfunction and acute ventricular failure are important to define a convenient diagnosis and treatment oriented towards pathophysiology. In this first part, the anatomy and physiology, acute right ventricular dysfunction/failure and cardiogenic shock are taken into consideration, from the perspective of these two entities. In another paper, treatment aimed at cardiogenic shock due to right ventricular involvement will be reviewed. [ABSTRACT FROM AUTHOR]

Introduction: Hypertension constitutes a health problem worldwide, due to the progressive increase of its prevalence and incidence. Objective: To describe the main clinical and epidemiologic characteristics of patients with hypertension. Methods: A descriptive, cross-sectional and ambispective study was carried out from April, 2020 to the same month in 2021 of 50 patients with hypertension assisted in La Morita Doctor's Office of Progreso Community Integral Health Area, Portuguese state, in the Bolivian Republic of Venezuela. In the statistical process of the information the percentage as summary measure was used. Results: In the series there was prevalence of the 80 years and over age group (26.0%), female sex (54.0%), the combined treatment (70.0%), and the consumption of coffee (96.0%) and tobacco (78.0%) as toxic habits and acute heart attack as main complication. Conclusions: The achievement of the suitable therapeutic plan, knowledge on the disease, healthy feeding, the frequent practice of physical exercises and the appropriate lifestyle are fundamental to maintain the blood pressure controlled and avoid the emergence of complications.

Background: Acute Myocardial Infarction (AMI) is a preventable pathology with modifiable factors, making it of interest in public health. Objective: To identifies the factors associated with AMI in patients with arterial hypertension. Material and Methods: This study employed a cross-sectional design with correlational phase, analyzing 130 medical records from the Friends of the Heart program at Hospital San Rafael of Tunja, Boyacá, Colombia, for the year 2016. The sample was selected using the simple random sampling technique. Results: Non-modifiable factors revealed a mean age of 70 years and a weight of 65 kg. Of the participants, 54.6% were male, and 40.8% belonged to the lower-middle class. Concerning modifiable factors, 30.8% reported alcohol consumption, 60% were smokers, and 94.6% were sedentary. 84.6% had high-normal blood pressure, 44.6% reported overweight, 53.1% consumed drugs, with 29.2% receiving insulin and 33.1% antidepressants, 46.2% presented moderate cardiovascular risk. Additionally, 92.3% had normal cholesterol levels, 32.3% were diagnosed with type II diabetes, and 43.8% had AMI. Evidence suggests an association between AMI and the insulin administration (p=0.003), antidepressants (p=0.021), and the comorbidity of Type II Diabetes (p=0.001). Conclusions: Modifiable risk factors associated with AMI were identified, with insulin administration standing out as a protective factor. [ABSTRACT FROM AUTHOR]

The article presents the case of a 64-year-old patient with acute myocardial infarction without ST segment elevation. During the procedure, a stent was placed in the coronary artery with subocclusive lesion. It was found that the patient had a single coronary artery and a quadricuspid aortic valve. Congenital anomalies of the coronary arteries are rare and can occur in isolation or in association with other cardiac malformations. Treatment should be individualized according to symptoms and associated lesions. In addition, the possible coexistence of the congenital anomaly of the quadricuspid aortic valve with other cardiac malformations is mentioned. [Extracted from the article]

This article presents a clinical case of a patient with acute myocardial infarction and an anomaly in the origin of the circumflex coronary artery that developed cardiogenic shock as a complication. The patient was treated with thrombolytics and pharmacoinvasive therapy, and underwent uncomplicated angioplasty with stent placement. The article highlights the complexity of cardiogenic shock and its high mortality rate in cases of acute myocardial infarction. The article describes a case of coronary artery anomalies in a patient with acute coronary syndrome complicated by cardiogenic shock. An anomalous origin of the circumflex coronary artery from the distal segment of the right coronary artery was found, which is unusual. This anomaly caused myocardial damage and ischemia in a larger territory, resulting in systolic dysfunction and cardiogenic shock. The treatment consisted of coronary reperfusion of the infarct-related artery. The identification of these anomalies is crucial for the management of patients with associated coronary artery disease.

Objective: To estimate the direct and indirect economic burden of hypercholesterolemia in patients with high risk of a car-diovascular event, specifically there were defined 5 groups of patients: 1) familial hypercholesterolemia; 2, 3 and 4) patients with hypercholesterolemia and background of diabetes, myocardial infarction or stroke; 5) diabetes, myocardial infarction and hypercholesterolemia (very high-risk patients) from the Mexican public healthcare institutions. Methods: For the estimation of the direct costs the items included correspond to: outpatient care, pharmacological treatment, inpatient hospital care, and surgical procedures. For indirect economic burden, death certificates, before the end of the productive age due to hypercho-lesterolemia were calculated (premature mortality). Results: The direct economic burden for the 5 groups of patients at risk is MXN $39,601,464,154 (USD $1,987,526,432), while the indirect economic burden amounts to MXN $121,646,689 (USD $6,105,229). Conclusions: The economic impact of hypercholesterolemia in patients with high cardiovascular risk is $39,723,110,843 (equivalent to USD $1,993,631,661) and corresponds to the 0.16% of GDP.

Cardiovascular diseases have a significant global impact as the leading cause of death. The renin-angiotensin system (RAS) plays a crucial role in the pathophysiology of these diseases, regulating renal, cardiac, and vascular physiology. Its activation has been linked to chronic conditions such as hypertension, heart failure, and kidney disease, primarily due to the activation of angiotensin-converting enzyme (ACE), whose metabolic products elicit an inflammatory and hypertrophic response. In recent years, the involvement of a counterregulatory RAS has been discovered, opposing the effects of the classic RAS. Of particular importance is ACE2, which generates Angiotensin-(1-7) and Angiotensin-(1-9), countering the pathological effects of the classic RAS. These peptides are active in myocardial ischemic events such as acute myocardial infarction (AMI), but little is known about their involvement in this pathology. The aim of this article is to review the cardioprotective potential of ACE2 and its products, Angiotensin-(1-7) and Angiotensin-(1-9), against Acute Myocardial Infarction. [ABSTRACT FROM AUTHOR]

Introduction: In the last two decades, advances in the percutaneous treatment of acute coronary syndrome have led to a reduction on its mortality, positioning percutaneous coronary intervention as the treatment of choice. The percutaneous coronary intervention is a challenging procedure due to its higher risk of related complications and the prevalence of multiple comorbidities. Objective: To evaluate the baseline profile and clinical outcomes over 6 months of follow-up post-percutaneous coronary intervention in patients older than 85 years-old submitted in the last three years to in-hospital coronary revascularization. Materials and method: This is an “all-comers” registry including patients ≥ 85 years-old treated with PCI in the last three years due to acute coronary syndrome. Results: We included 20 patients with a mean age of 90.3 years; of them, 55% female. The main comorbidities were: arterial hypertension (80%) and hyperlipidemia (58%). At the time of the intervention, 40% of the patients were diagnosed with ST-elevation coronary syndrome. Transradial percutaneous coronary intervention was performed on 70%, with successful target vessel revascularization in 90% of patients. There were 4 non-complicated vascular access-related bruises. Mortality was 0% over 6-months of follow-up. Conclusion: Percutaneous coronary intervention is a feasible and effective procedure with low rates of complications in patients over 85 years of age with diagnosis of acute coronary syndrome.

The article presents a clinical case of a patient with Takotsubo syndrome and acute arterial ischemia in the lower extremities. Takotsubo syndrome is a dysfunction of the left ventricle that simulates an acute myocardial infarction without coronary lesions. The patient, a 59-year-old man, experienced hypotension, chest pain, and acute ischemia in the lower extremities. Emergency revascularization was performed, and the patient had a favorable recovery. The article highlights the importance of a rapid and accurate cardiological diagnosis in cases like this. It also mentions that Takotsubo syndrome is more common in women and can be triggered by emotional stress, pheochromocytomas, neurological events, or underlying coronary disease.

Introduction: Coronary Ectasia (CE) is a pathological remodeling with a low worldwide prevalence. It is defined as a diffuse dilatation greater than 1.5 times the diameter of the adjacent segments of the same or different coronary arteries. Objective: To document the clinical and angiographic characteristics, and medical treatment at the discharge of patients diagnosed with coronary ectasia who attended the National Institute of Cardiology (INC). Methods: Cross-sectional study with a non-experimental descriptive design, with a non-probabilistic convenience sampling. Results: Of 69 patients who attended the INC with a diagnosis of CD, most were men, with a mean age of 56 + 11 years, the most common coronary risk factor in patients with CE was smoking 58% (40); it was associated mostly with an acute myocardial infarction ST-segment elevation (STEMI) 65.2% (45), of frequent location in the lower face 40% (18), correlated with the most affected artery is the Right Coronary Artery (CD) 69.6% (48), followed by the circumflex (Cx) 56.5% (39). A mean LVEF of 47 + 9.72 was evident within the ventricular function. As well as the preferential use of dual antiplatelet therapy with anticoagulant (DAP + OAC) in 58% (40) at the discharge of each patient from the INC. Conclusion: CE is a not uncommon pathological remodeling in INC. This study showed that STEMI is the most typical manifestation of CE, diagnostic coronary angiography identified a type 3 Markis, so a low rate of mortality and recurrence of cardiovascular events would be expected, and despite the lack of consensus on the ideal therapy, at the INC individualized treatment is preferred, recommending lifestyle changes, and using triple therapy (DAP + OAC) as a medical treatment only at the time of patient discharge.
