- Abstract
Background: Bioresorbable scaffolds (BRS) have been proposed as an alternative to drug-eluting stents (DES), offering radial support during the early phases of healing, while potentially reducing the risk of long-term complications. A magnesium-based BRS (MgBRS) has shown promising results after implantation. However, there is a lack of knowledge regarding the long-term outcomes., Case Summary: A 62-year-old man with hypertension, dyslipidaemia, family history of ischaemic heart disease, and previous myocardial infarction, presented with non-ST-elevation myocardial infarction (NSTEMI). Six years prior, he also had a NSTEMI and a mid-left anterior descending artery (LAD) lesion was treated with a 3.0/25 mm MgBRS. Post-implantation optical coherence tomography (OCT) revealed proximal edge dissection, and a second MgBRS 3.0/15 mm was implanted. Optical coherence tomography of the scaffold-treated segment was performed after 6 and 12 months with no sign of restenosis. The current angiogram showed a restenosis in the previously MgBRS-treated segment in LAD. Optical coherence tomography showed a plaque rupture in a thin cap fibro-atheroma and scaffold remnants. The lesion was pre-dilated and stented with a 3.0/20 mm DES and post-dilated with a 3.5 mm non-compliant balloon., Discussion: Most cases of late scaffold failure showed acquired mal-apposition, which also can be related to the degrading process, or uncovered struts, none of which were seen in our case at 6 or 12 months. This case represents an insight into the vascular healing and potential mechanisms for failure of the MgBRS, with serial OCT recording at implantation, and after 6 months, 12 months, and 6 years., Competing Interests: Conflict of interest: L.O.J. has received research grants from Biotronik and Biosensors to her institution.

- Abstract
Background and Aims: Guidelines recommend revascularization of intermediate epicardial artery stenosis to be guided by evidence of ischaemia. Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are equally recommended. Individual 5-year results of two major randomized trials comparing FFR with iFR-guided revascularization suggested increased all-cause mortality following iFR-guided revascularization. The aim of this study was a study-level meta-analysis of the 5-year outcome data in iFR-SWEDEHEART (NCT02166736) and DEFINE-FLAIR (NCT02053038)., Methods: Composite of major adverse cardiovascular events (MACE) and its individual components [all-cause death, myocardial infarction (MI), and unplanned revascularisation] were analysed. Raw Kaplan-Meier estimates, numbers at risk, and number of events were extracted at 5-year follow-up and analysed using the ipdfc package (Stata version 18, StataCorp, College Station, TX, USA)., Results: In total, iFR and FFR-guided revascularization was performed in 2254 and 2257 patients, respectively. Revascularization was more often deferred in the iFR group [n = 1128 (50.0%)] vs. the FFR group [n = 1021 (45.2%); P = .001]. In the iFR-guided group, the number of deaths, MACE, unplanned revascularization, and MI was 188 (8.3%), 484 (21.5%), 235 (10.4%), and 123 (5.5%) vs. 143 (6.3%), 420 (18.6%), 241 (10.7%), and 123 (5.4%) in the FFR group. Hazard ratio [95% confidence interval (CI)] estimates for MACE were 1.18 [1.04; 1.34], all-cause mortality 1.34 [1.08; 1.67], unplanned revascularization 0.99 [0.83; 1.19], and MI 1.02 [0.80; 1.32]., Conclusions: Five-year all-cause mortality and MACE rates were increased with revascularization guided by iFR compared to FFR. Rates of unplanned revascularization and MI were equal in the two groups., (© The Author(s) 2023. Published by Oxford University Press on behalf of the European Society of Cardiology.

- Abstract
Aims: The objectives were to describe differences in self-reported health at discharge between women diagnosed with angina or unspecific chest pain and investigate the association between self-reported health and adverse outcomes within 3 years., Methods and Results: Data from a national cohort study were used, including data from the DenHeart survey combined with 3 years of register-based follow-up. The population included two groups of women with symptoms of angina but no diagnosis of obstructive coronary artery disease at discharge (women with angina and women with unspecific chest pain). Self-reported health measured with validated instruments was combined with register-based follow-up on adverse outcomes (a composite of unplanned cardiac readmissions, revascularization, or all-cause mortality). Associations between self-reported health and time to first adverse outcomes were investigated with Cox proportional hazard models, reported as hazards ratios with 95% confidence intervals. In total, 1770 women completed the questionnaire (49%). Women with angina (n = 931) reported significantly worse self-reported health on several outcomes compared to women with unspecific chest pain (n = 839). Within the 3 years follow-up, women with angina were more often readmitted (29 vs. 23%, P = 0.011) and more underwent revascularization (10 vs. 1%, P < 0.001), whereas mortality rates were similar (4 vs. 4%, P = 0.750). Self-reported health (physical and mental) was associated with adverse outcomes between both groups (on most instruments)., Conclusion: Women with angina reported significantly worse self-reported health on most instruments compared to women with unspecific chest pain. Adverse outcomes varied between groups, with women diagnosed with angina experiencing more events., Registration: ClinicalTrials.gov (NCT01926145)., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2022.

- Abstract
Aims: Cardiogenic shock (CS) is known to induce an inflammatory response. The prognostic utility of this remains unclear. To investigate the association between C-reactive protein (CRP) levels and leucocyte count and mortality in patients with acute myocardial infarction complicated by CS (AMICS)., Methods and Results: Consecutive patients (N = 1716) admitted between 2010 and 2017 with an individually validated diagnosis of AMICS were included. The analysis was restricted to patients alive at 48 h after first medical contact and a valid CRP and leucocyte measurement at 48 ± 12 h from the first medical contact. A combined inflammatory score for each patient was computed by summing the CRP and leucocyte count z-scores to normalize the response on a standard deviation scale. Associations with mortality were analysed using a multivariable Cox proportional hazards model stratified by inflammatory response quartiles: Of the 1716 patients in the cohort, 1111 (64.7%) fulfilled inclusion criteria. The median CRP level at 48 h was 145 mg/dL [interquartile range (IQR) 96-211]. The median leucocyte count was 12.6 × 10-9/L (IQR 10.1-16.4). Patients with the highest inflammatory response (Q4) had lower median left ventricular ejection fractions and higher lactate levels at the time of diagnosis. The 30-day all-cause mortality rates were 46% in Q4 and 21% in Q1 (P < 0.001). In multivariable models, the inflammatory response remained associated with mortality [hazard ratio (HR)Q4 2.32, 95% confidence interval (CI) 1.59-3.39, P < 0.001]. The finding was also significant in AMICS patients presenting with out-of-hospital cardiac arrest following multivariable adjustment (HRQ4 3.37, 95% CI 2.02-4.64, P < 0.001)., Conclusion: Cardiogenic shock induces an acute inflammatory response, the severity of which is associated with mortality., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

- Abstract
Aim: The no-or-slow-reflow phenomenon after primary percutaneous coronary intervention is associated with more extensive myocardial injury in patients with ST-elevation myocardial infarction (STEMI). Soluble suppression of tumourigenicity 2 (sST2) is released in acute myocardial response to injury, and an increase in plasma level in the initial phase of STEMI is associated with increased mortality and risk of heart failure. We have therefore explored the association of pre-intervention plasma sST2 with the post-procedural no-or-slow-reflow phenomenon in patients with STEMI., Methods and Results: We included consecutive patients with verified STEMI from two tertiary heart centres. Blood samples were collected at admission before angiography. Post-procedural coronary flow was assessed according to thrombolysis in myocardial infarction (TIMI) classification for STEMI. Patients were divided into two groups: post-procedural TIMI 0-2 as no-or-slow reflow and TIMI 3 as normal reflow. The association between sST2 and TIMI flow was explored using multiple logistic regression. A total of 1607 patients with available TIMI flow classification were included in the analysis. Normal reflow was seen in 1520 (94.6%), while 87 (5.4%) had no-or-slow reflow. No-or-slow-reflow patients had higher all-cause 30-day mortality [10 (11%) vs. 65 (4.3%), P = 0.006]. Pre-procedural sST2 was higher in the no-or-slow-flow group [47 ng/mL, interquartile range (IQR, 33-83) vs. 39 ng/mL (IQR 29-55), P < 0.001] and was independently associated with post-procedural no-or-slow flow [two-fold sST2 increase: odds ratio 1.44 (1.15-1.78), P = 0.0012]., Conclusion: In patients with STEMI, the sST2 level at admission before coronary angiography is independently associated with the post-procedural no-or-slow-reflow phenomenon., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2022.

- Abstract
Aims: The aim of this study was to evaluate the association between coronary computed tomography angiography (CCTA)-derived fractional flow reserve (FFRCT) and recurrent chest pain (CP) at 1-year follow-up in patients with stable angina pectoris (SAP)., Methods and Results: Study of patients (n = 267) with SAP who underwent CCTA and FFRCT testing; 236 (88%) underwent invasive coronary angiography; and 87 (33%) were revascularized. Symptomatic status at 1-year follow-up was gathered by a structured interview. Three different FFRCT algorithms were applied using the following criteria for abnormality: (i) 2 cm-FFRCT ≤0.80; (ii) d-FFRCT ≤0.80; and (iii) a combination in which both a d-FFRCT ≤0.80 and a ΔFFRCT ≥0.06 must be present in the same vessel (c-FFRCT). Patients were classified into two groups based on the FFRCT test result and revascularization: completely revascularized/normal (CRN), patients in whom all coronary arteries with an abnormal FFRCT test result were revascularized or patients with completely normal FFRCT test results, and incompletely revascularized (IR), patients in whom ≥1 coronary artery with an abnormal FFRCT test result was not revascularized. Recurrent CP was present in 62 (23%) patients. Classification of patients (CRN or IR) was significantly associated with recurrent CP for all applied FFRCT interpretation algorithms. When applying the c-FFRCT algorithm, the association with recurrent CP was found, irrespective of the extent of coronary calcification and the degree of coronary stenosis. A negative association between per-patient minimal d-FFRCT and recurrent CP was demonstrated, P < 0.005., Conclusion: An abnormal FFRCT test result is associated with an increased risk of recurrent CP in patients with new-onset SAP., Competing Interests: Conflict of interest: L.O.J. has received institutional research grants from St. Jude Medical, Biosensors, and Biotronik.

- Abstract
Background: Cardiogenic shock is the leading cause of death in patients with acute myocardial infarction, with short-term mortality of approximately 50%. Whether diabetes mellitus and high blood glucose levels are associated with mortality in contemporary patients with acute myocardial infarction complicated by cardiogenic shock is inadequately described., Purpose: To investigate if diabetes mellitus and high admission blood glucose were associated with 30-day mortality in a large, contemporary population with acute myocardial infarction complicated by cardiogenic shock., Methods: Patients with acute myocardial infarction complicated by cardiogenic shock admitted at two tertiary centres in Denmark from 2010 to 2017 were individually identified through patient charts, resulting in the inclusion of 1716 cardiogenic shock patients. Glucose level at admission to the intensive care unit was available in 1302 patients., Results: There was no significant difference in 30-day mortality between diabetes mellitus types I and II (63% vs. 62%, NS). Thirty-day mortality was significantly higher in diabetes patients compared to non-diabetes patients (62% vs. 50%, P < 0.001). Increasing admission glucose was associated with increasing 30-day mortality in a dose-dependent manner in diabetes mellitus (4-8 mmol/L, 41%; 8-12 mmol/L, 49%; 12-16 mmol/L, 63%; >16 mmol/L, 67%; P = 0.028) and non-diabetes patients (4-8 mmol/L, 32%; 8-12 mmol/L, 43%; 12-16 mmol/L, 57%; >16 mmol/l; 68%; P < 0.001)., Conclusion: Patients with acute myocardial infarction complicated by cardiogenic shock and concomitant diabetes mellitus type I or II had a significantly higher 30-day mortality in comparison to patients without diabetes mellitus, whereas no difference was found between diabetes mellitus types I and II. High glucose levels on admission to the intensive care unit were associated with increased 30-day mortality in diabetes mellitus and non-diabetes mellitus patients.

- Abstract
Aims: Smoking is an important modifiable risk factor for myocardial infarction. It is unclear whether smoking habits at the time of an incident ST-segment elevation myocardial infarction (STEMI) differ across age groups and sex., Methods and Results: We included patients with incident STEMI registered in the Western Denmark Heart Registry from 2005 to 2015 ( n =9914). Patients were divided into four age groups (30-49, 50-59, 60-69 and ⩾70 years) with the latter serving as reference. Smoking was the most prevalent modifiable risk factor in 30-49-year-old patients (74% vs. hypertension 15%, hyperlipidaemia 10% and diabetes 7%). The smoking prevalence decreased with increasing age, while treatment for hypertension, hyperlipidaemia and diabetes increased with increasing age. Smoking was five times (odds ratio (OR) 5.15; 95% confidence interval (CI) 4.37-6.07) more prevalent among 30-49-year-old patients with STEMI than the reference group. Differences according to sex were significant as the OR for current smoking in women was 9.88 (95% CI 6.94-14.08) compared to OR 3.78 (95% CI 3.12-4.58) in men., Conclusions: Despite public information campaigns and general warnings, smoking remains the most prevalent modifiable risk factor in younger patients with STEMI.

- Abstract
Aims: The current guidelines from the European Society of Cardiology and European Society of Anaesthesiology on non-cardiac surgery (ESC/ESA-NCS) divide surgical procedures into those associated with low risk (<1%), intermediate risk (1-5%), and high risk (>5%) of major adverse cardiac events (MACE). Evaluating surgical risk might be particularly appropriate in patients with recent stent implantation, and thus we validated the ESC/ESA-NCS classification in patients undergoing NCS within 1 year after coronary drug-eluting stent (DES) implantation., Methods and Results: By record-linking the Western Denmark Heart Registry and the Danish National Patient Registry, we identified 4046 patients, who underwent NCS between 1 and 12 months after DES implantation. Primary outcomes were MACE [cardiac death and myocardial infarction (MI)] and a combined endpoint of mortality and MI within 30 days after surgery. Both MACE (low risk 0.6%, intermediate risk 1.2%, and high risk 3.4%) and the combined endpoint of mortality and MI (1.5%, 4.6%, and 14.9%) were associated with the ESC/ESA-NCS classification. As compared with low-risk surgery, the odds ratios (OR) for MACE were 1.9 [95% confidence interval (CI) 0.9-4.1] for intermediate-risk surgery and 5.8 (95% CI 1.7-20.1) for high-risk surgery. For the combined endpoint of mortality and MI, the OR's were 3.1 (95% CI 2.1-4.7) for intermediate-risk surgery and 11.3 (95% CI 5.9-21.9) for high-risk surgery., Conclusion: The ESC/ESA-NCS classification is a valid tool to predict the risk of both MACE and the combined endpoint of mortality and MI for patients undergoing NCS.

- Abstract
Background: The incidence of cardiogenic shock (CS) in patients with ST-segment elevation myocardial infarction (STEMI) is as high as 10%. The majority of patients are thought to develop CS after admission (late CS), but the incidence in a contemporary STEMI cohort admitted for primary percutaneous intervention remains unknown., Aim: The aim of this study was to assess the incidence and time of CS onset in patients with suspected STEMI admitted in two high-volume tertiary heart centres and to assess the variables associated with the development of late CS., Methods: We included consecutive patients admitted for acute coronary angiography with suspected STEMI in a 1-year period. Cardiogenic shock was based on clinical criteria and subdivided into patients with shock on admission, patients developing shock during catheterisation and patients developing shock later during hospitalisation. Follow-up for all-cause mortality was done using registries., Results: A total of 2247 patients with suspected STEMI were included, whereof 225 (10%) developed CS. The majority (56%) had CS on admission, 16% developed CS in the catheterisation laboratory and 28% developed late CS. Thirty-day mortality was 3.1% versus 47% in non-CS versus CS patients ( p
logrank < 0.0001). Age, stroke, time from symptom onset to intervention, anterior STEMI, heart rate/systolic blood pressure ratio and being comatose after resuscitation from cardiac arrest were independently associated with the development of late CS., Conclusion: In this study, 10% of patients admitted with suspected STEMI for acute coronary angiography presented with or developed CS. Most were in shock on admission. Irrespective of the timing of shock, mortality was high.- Published

- Abstract
Rationale: Short-term mechanical circulatory support is increasingly used in the management of cardiogenic shock, but data from controlled studies are sparse. Thus, real-life data on complication rates and predictors of adverse outcome are important., Objective: The objective of this study was to analyse the experience with Impella devices in the management of profound cardiogenic shock., Methods and Results: A retrospective study of 109 consecutive patients with severe shock after myocardial infarction, acute heart failure, or cardiac surgery. Possible device-related complications were registered and predictors of death while on Impella support and within 180 days were identified. In 79 patients (72%) cardiogenic shock was caused by myocardial infarction, acute heart failure in 16 (15%) and post-cardiotomy shock in 14 patients (13%). Thirty-five patients (32%) were comatose after cardiac arrest and in seven, the Impella was placed during chest compression. Mean age was 62±12 years, mean arterial pressure was 57±13 mmHg, pH 7.19±0.17 and lactate 7.5±5.7 mmol/l (range 1.8-30.0 mmol/l) at placement. During Impella therapy, 26 patients (28%) died among patients with myocardial infarction or acute heart failure. Of data available prior to placement lactate (hazard ratio 1.14, 95% confidence interval 1.04-1.25, P=0.004) was the only predictor of death on support. During support, five patients (5%) developed leg ischaemia requiring intervention. Bleeding from the Impella insertion site was seen in 14 patients (13%)., Conclusion: Impella treatment is feasible in profound cardiogenic shock at an acceptable rate of complications. Despite an aggressive approach to restore cardiac output, mortality was high. Besides the severity of lactic acidosis there were no strong predictors of early death.

- Abstract
Aims: To evaluate whether the distance from the site of event to an invasive heart centre, acute coronary angiography (CAG)/percutaneous coronary intervention (PCI) and hospital-level of care (invasive heart centre vs. local hospital) is associated with survival in out-of-hospital cardiac arrest (OHCA) patients., Methods and Results: Nationwide historical follow-up study of 41 186 unselected OHCA patients, in whom resuscitation was attempted between 2001 and 2013, identified through the Danish Cardiac Arrest Registry. We observed an increase in the proportion of patients receiving bystander CPR (18% in 2001, 60% in 2013, P < 0.001), achieving return of spontaneous circulation (ROSC) (10% in 2001, 29% in 2013, P < 0.001) and being admitted directly to an invasive centre (26% in 2001, 45% in 2013, P < 0.001). Simultaneously, 30-day survival rose from 5% in 2001 to 12% in 2013, P < 0.001. Among patients achieving ROSC, a larger proportion underwent acute CAG/PCI (5% in 2001, 27% in 2013, P < 0.001). The proportion of patients undergoing acute CAG/PCI annually in each region was defined as the CAG/PCI index. The following variables were associated with lower mortality in multivariable analyses: direct admission to invasive heart centre (HR 0.91, 95% CI: 0.89-0.93), CAG/PCI index (HR 0.33, 95% CI: 0.25-0.45), population density above 2000 per square kilometre (HR 0.94, 95% CI: 0.89-0.98), bystander CPR (HR 0.97, 95% CI: 0.95-0.99) and witnessed OHCA (HR 0.87, 95% CI: 0.85-0.89), whereas distance to the nearest invasive centre was not associated with survival., Conclusion: Admission to an invasive heart centre and regional performance of acute CAG/PCI were associated with improved survival in OHCA patients, whereas distance to the invasive centre was not. These results support a centralized strategy for immediate post-resuscitation care in OHCA patients., (© The Author 2017. Published on behalf of the European Society of Cardiology.)

- Abstract
Aims: Reporting of quantitative myocardial blood flow (MBF) is typically performed in standard coronary territories. However, coronary anatomy and myocardial vascular territories vary among individuals, and a coronary artery may erroneously be deemed stenosed or not if territorial demarcation is incorrect. So far, the diagnostic consequences of calculating individually vs. standardly assessed MBF values have not been reported. We examined whether individual reassignment of vascular territories would improve the diagnostic accuracy of MBF with regard to the detection of significant coronary artery disease (CAD)., Methods and Results: Forty-four patients with suspected CAD were included prospectively and underwent coronary CT-angiography and quantitative MBF assessment with O-15-water PET followed by invasive, quantitative coronary angiography, which served as reference. MBF was calculated in the vascular territories during adenosine stress according to a standardized 17-segment American Heart Association model and an individualized model, using CT-angiography to adjust the coronary territories to their feeding vessels. Individually defined territories deviated from standard territories in 52% of patients. However, MBF in the three coronary territories defined by standard and individualized models did not differ significantly, except in one patient, in whom the MBF of an individualized coronary territory deviated sufficiently as to change the test from a false positive to a true negative result in this particular territory., Conclusion: Disparity between standardized and individualized vascular territories was present in half of the patients, but had little clinical impact. Still, caution should be taken not always to rely on standard territories, as this may at times cause misinterpretation., (Published on behalf of the European Society of Cardiology.

- Abstract
Background: In patients undergoing coronary angiography or percutaneous coronary intervention (PCI), the standard post procedure regime includes immobilization and bed rest despite the use of vascular closure devices., Aim: In the Mobilization after Coronary Angiography or Percutaneous Coronary Intervention (MOBS) study we compared bleeding complications after cardiac catheterization with femoral artery access after mobilization immediately off the angiographic table or standard care with1 hour (MOBS I after a diagnostic angiogram) or 2 hours of bed rest before mobilization (MOBS II after PCI)., Methods: Bleeding complications were defined as major (requiring surgery of the femoral artery, transfusion or increased hospital stay) and minor (hematoma <5 × 5 cm(2), oozing from the puncture site or minor bleeding that could be compressed manually)., Results: In the MOBS I cohort (100 patients were mobilized immediately and 100 patients followed standard care) no major bleeding complications were seen. In the immediate mobilization group 2.0% experienced minor bleeding compared to 4.0% in the standard care group (p=0.41). In the MOBS II cohort after PCI (158 patients were mobilized immediately and 161 patients followed standard care), major bleeding complication rates did not differ significantly between the two groups: immediate mobilization group 26.6% vs. standard care group 28.0%, p=0.78. The majority of bleeding complications were due to oozing: immediate mobilization group 22.8% vs. standard care group 20.5%, p=0.62., Conclusions: Immediate mobilization after a coronary angiogram or PCI with the femoral access site closed by the closure device AngioSeal was not associated with increased bleeding risk compared to standard care with bed rest., (© The European Society of Cardiology 2013.)

- Abstract
Aims: Patients with diabetes have increased risk of in-stent restenosis after coronary stent implantation owing to neointimal hyperplasia (NIH). The aim of the study was to evaluate the extent and distribution of NIH with intravascular ultrasound (IVUS) after coronary artery stenting with sirolimus-eluting (Cypher) or paclitaxel-eluting (Taxus) stents in diabetic patients., Methods and Results: One hundred and thirty diabetic patients were randomized to Cypher or Taxus stent implantation. IVUS was performed at 8 month follow-up. NIH volume was significantly reduced in the Cypher group when compared with the Taxus group: median (inter-quartile range) 0.0 (0.0-0.0) vs. 8.0 mm(3) (0.1-33.0), P < 0.001. Per cent NIH volume was also significantly lower in Cypher stents compared with Taxus stents: median (inter-quartile range) 0.0 (0.0-0.0) vs. 7.5% (0.1-27.0), P < 0.001. NIH was covering 5.4% of the stent length in the Cypher stents compared with 46.1% in the Taxus stents (P < 0.001). The incidence of diffuse NIH was significantly higher for Taxus than for Cypher stents (42.9 vs. 3.5%, P < 0.001). Taxus stents had more often NIH at the proximal stent edge compared with Cypher stents (45.1 vs. 7%, P < 0.001) and no Cypher stents had NIH at the distal stent edge compared with 35.5% of the Taxus stents (P < 0.001)., Conclusion: In diabetic patients, the Cypher stent, compared with the Taxus stent, inhibited NIH more effectively and had a more focal NIH pattern including less involvement of the stent edges.

- Abstract
Aims: Collateral flow may influence long-term results after percutaneous coronary intervention (PCI) because of haemodynamic forces compete with the antegrade flow through the dilated lesion. The aim of the study was to assess the influence of recruitable collateral blood flow on restenosis in patients undergoing PCI with bare metal stents and using optimal antithrombotic treatment., Methods and Results: In 95 patients, 95 de novo lesions were treated with PCI and a bare metal stent. Fractional flow reserve (FFR) at maximum hyperaemia induced by intravenous adenosine was determined. The pressure-derived collateral flow index (CFI) was determined as (P(w)-P(cvp))/(P(a)-P(cvp)), where P(w) represents coronary wedge pressure, P(cvp) central venous pressure, and P(a) mean aortic blood pressure. Both were measured during transient coronary occlusion by a balloon inflation of 30 s. Pre-interventional FFR (0.65 +/- 0.20) correlated inversely with the CFI (0.18 +/- 0.11), r =- 0.356, P < 0.001. After 9 months, binary angiographic restenosis (>/=50% diameter stenosis) was seen in 29.1%. Compared to patients with poorly developed collaterals (CFI < 0.25), patients with well-developed collaterals (CFI >/= 0.25) had a lower pre-interventional FFR (0.50 +/- 0.14 vs. 0.72 +/- 0.18, P < 0.001), a higher CFI (0.33 +/- 0.08 vs. 0.13 +/- 0.07, P < 0.001), and a higher binary restenosis rate (54.2% vs. 19.4, P = 0.003). CFI*100 was an independent predictor of restenosis after 9 months (odds ratio 1.07, 95% CI 1.02-1.12, P = 0.016)., Conclusion: Recruitable collateral blood flow measured during balloon inflation predicts angiographic instent restenosis in PCI patients treated with bare metal stents.

- Abstract
Aims: Intravascular ultrasound (IVUS) assesses arterial remodelling by comparing the lesion external elastic membrane (EEM) with the reference segments; however, reference segments are rarely disease-free. The aim was to assess lesion and reference segment remodelling and plaque burden in patients with type-2 diabetes mellitus., Methods and Results: We used pre-intervention IVUS to study 62 de novo lesions in 43 patients with type-2 diabetes mellitus. The lesion site was the image slice with the smallest lumen cross-sectional area (CSA). The proximal and distal reference segments were the most normal-looking segments within 5 mm proximal and distal to the lesion. Plaque burden was measured as plaque CSA/EEM CSA. The remodelling index was defined as lesion EEM CSA/mean reference EEM CSA. Reference segment plaque burden measured 0.54 +/- 0.09. The majority of lesions (83.9%) had negative remodelling (lesion EEM < reference). Similarly, the slope of the regression line relating EEM to plaque CSA within the lesion was less than the reference substantiating negative remodelling. The reference segment plaque burden correlated inversely with the difference between IVUS lumen and quantitative coronary angiographic artery size [slope = -0.12 (95% CI -0.17 to -0.07); P < 0.001] in all patients with type-2 diabetes mellitus., Conclusion: Lesions in type-2 diabetic patients are different from previous reports in non-diabetics. Lesions in type-2 diabetics are characterized by a large reference segment plaque burden and negative lesion site remodelling. These IVUS findings may explain the angiographic appearance of small arteries in diabetic patients.
