Item type:Publication, The no-reflow phenomenon in the young and in the elderly(Elsevier BV, 2016-11-01); ; Câlmâc, LucianBackground The objectives of this study were to evaluate the incidence of no-reflow as independent predictor of adverse events and to assess whether baseline pre-procedural treatment options may affect clinical outcomes. Methods Data were derived from the ISACS-TC registry (NCT01218776) from October 2010 to January 2015. No-reflow was defined as post-PCI TIMI flow grades 0–1, in the absence of post-procedural significant (≥25%) residual stenosis, abrupt vessel closure, dissection, perforation, thrombus of the original target lesion, or epicardial spasm. The outcome measure was in-hospital mortality. Results No-reflow was identified in 128 of 5997 patients who have undergone PCI (2.1%). On multivariate analysis, patients with no-reflow were more likely to be older (OR: 1.20, 95% CI: 1.01–1.44), to have a history of hypercholesterolemia (OR: 1.95, 95% CI: 1.31–2.91) and to be admitted with a diagnosis of STEMI (OR: 2.96, 95% CI: 1.85–4.72). Angiographic characteristics associated with no-reflow phenomenon were: stenosis ≥50% of the right coronary artery, presence of multivessel disease and pre-procedural TIMI blood flow grades 0–1. No-reflow was highly predictive of in-hospital mortality (17.2% vs. 4.2%; adjusted OR: 4.60, 95% CI: 2.61–8.09). Administration of pre-procedural unfractioned heparin or 600mg clopidogrel loading dose was associated with less incidence of no-reflow (OR: 0.65, 95% CI: 0.43–0.99 and 0.61, 95% CI: 0.37–1.00, respectively). Aspirin, enoxaparin, and 300mg clopidogrel loading dose, did not significantly impact the occurrence of the no-reflow. Conclusions We found that pre-procedural administration of 600mg loading dose of clopidogrel and/or unfractioned heparin is associated with reduced incidence of no-reflow. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Sex Differences in Modifiable Risk Factors and Severity of Coronary Artery Disease(2020-10-20); Background It is still unknown whether traditional risk factors may have a sex-specific impact on coronary artery disease (CAD) burden. Methods and Results We identified 14 793 patients who underwent coronary angiography for acute coronary syndromes in the ISACS-TC (International Survey of Acute Coronary Syndromes in Transitional Countries; ClinicalTrials.gov, NCT01218776) registry from 2010 to 2019. The main outcome measure was the association between traditional risk factors and severity of CAD and its relationship with 30-day mortality. Relative risk (RR) ratios and 95% CIs were calculated from the ratio of the absolute risks of women versus men using inverse probability of weighting. Estimates were compared by test of interaction on the log scale. Severity of CAD was categorized as obstructive (≥50% stenosis) versus nonobstructive CAD. The RR ratio for obstructive CAD in women versus men among people without diabetes mellitus was 0.49 (95% CI, 0.41-0.60) and among those with diabetes mellitus was 0.89 (95% CI, 0.62-1.29), with an interaction by diabetes mellitus status of P =0.002. Exposure to smoking shifted the RR ratios from 0.50 (95% CI, 0.41-0.61) in nonsmokers to 0.75 (95% CI, 0.54-1.03) in current smokers, with an interaction by smoking status of P=0.018. There were no significant sex-related interactions with hypercholesterolemia and hypertension. Women with obstructive CAD had higher 30-day mortality rates than men (RR, 1.75; 95% CI, 1.48-2.07). No sex differences in mortality were observed in patients with nonobstructive CAD. Conclusions Obstructive CAD in women signifies a higher risk for mortality compared with men. Current smoking and diabetes mellitus disproportionally increase the risk of obstructive CAD in women. Achieving the goal of improving cardiovascular health in women still requires intensive efforts toward further implementation of lifestyle and treatment interventions.

Item type:Publication, Sex-Specific Treatment Effects After Primary Percutaneous Intervention: A Study on Coronary Blood Flow and Delay to Hospital Presentation(2019); Background We hypothesized that female sex is a treatment effect modifier of blood flow and related 30-day mortality after primary percutaneous coronary intervention ( PCI ) for ST -segment-elevation myocardial infarction and that the magnitude of the effect on outcomes differs depending on delay to hospital presentation. Methods and Results We identified 2596 patients enrolled in the ISACS - TC (International Survey of Acute Coronary Syndromes in Transitional Countries) registry from 2010 to 2016. Primary outcome was the occurrence of 30-day mortality. Key secondary outcome was the rate of suboptimal post- PCI Thrombolysis in Myocardial Infarction ( TIMI ; flow grade 0-2). Multivariate logistic regression and inverse probability of treatment weighted models were adjusted for baseline clinical covariates. We characterized patient outcomes associated with a delay from symptom onset to hospital presentation of ≤120 minutes. In multivariable regression models, female sex was associated with postprocedural TIMI flow grade 0 to 2 (odds ratio [ OR ], 1.68; 95% CI , 1.15-2.44) and higher mortality ( OR, 1.72; 95% CI , 1.02-2.90). Using inverse probability of treatment weighting, 30-day mortality was higher in women compared with men (4.8% versus 2.5%; OR , 2.00; 95% CI , 1.27-3.15). Likewise, we found a significant sex difference in post- PCI TIMI flow grade 0 to 2 (8.8% versus 5.0%; OR , 1.83; 95% CI , 1.31-2.56). The sex gap in mortality was no longer significant for patients having hospital presentation of ≤120 minutes ( OR , 1.28; 95% CI , 0.35-4.69). Sex difference in post- PCI TIMI flow grade was consistent regardless of time to hospital presentation. Conclusions Delay to hospital presentation and suboptimal post- PCI TIMI flow grade are variables independently associated with excess mortality in women, suggesting complementary mechanisms of reduced survival.
