We aimed to demonstrate the clinical utility of CHA2DS2-VASc score in risk assessment patients with STEMI regarding adverse outcomes particularly no-reflow phenomenon. designed a retrospective cohort study using data Tehran Heart Center registry for acute coronary syndrome. The included 1331 consecutive who underwent primary angioplasty. Patients were divided into two groups according low and high score. Angiographic results reperfusion inspected evaluate association likelihood suboptimal...

Abstract The association between coronary arterial dominance patterns and the artery diameter, length, valvular heart diseases were previously studied. However, its with disease (CAD) is unclear. We investigated to determine whether extent localization of CAD differ in right, left, or codominant patterns. Twelve thousand five hundred fifty‐eight patients admitted Tehran Heart Center for angiography studied retrospectively (2004–2006). dominant determined. There 62.7% males. mean age was 57.6...

Serum gamma-glutamyltransferase (GGT) has been introduced as a predictive factor for cardiovascular disease. In this study, we investigated the association of serum GGT and premature coronary artery disease (CAD) in candidates angiography. cross-sectional enrolled male subjects aged ≤45 years female ≤55 who were elective angiography due to typical chest pain or positive non-invasive test. Baseline characteristics recorded all participants levels blood glucose, lipid profile measured....

Due to uncertainty in the clinical implications of slow coronary flow (SCF), we aimed investigate features and mid-term outcome Iranian patients with phenomenon.During a four-year period from January 2005 December 2009, out 3523 consecutive who underwent angiography Tehran Heart Center, 325 no stenosis, ectasia, or aneurysm were enrolled study. Among them 81 (2.2%) diagnosed SCF. Baseline characteristics, lab parameters, risk factors described, consequently. RESUITS: Typical chest pain was...

Abstract Aim Achieving the optimal apposition of coronary stents during percutaneous intervention is not always feasible. The risks and benefits stent postdilation in primary (PPCI) patients with ST‐elevation myocardial infarction (STEMI) have remained controversial. We sought to evaluate immediate angiographic long‐term outcomes without postdilation. Methods A cohort ( n = 1,224) STEMI, treated PPCI 500 postdilated; 724 controls), were studied. flow grade, blush frame count considered...

This case series explores three patients who underwent percutaneous coronary intervention (PCI) and experienced prolonged QT intervals under treatment with Ticagrelor. The first was a female presented chest pain received Xience stent. second involved male patient two stents. third that of LAD stenosis. All Ticagrelor exhibited QTc on their electrocardiograms (ECGs), which resolved after switching to Clopidogrel. Thus far, the potential impact prolongation has not been adequately addressed in...

Background: Primary percutaneous coronary intervention (PPCI) as the treatment of choice for ST‑segment elevation myocardial infarction (STEMI) should be rapidly performed. It is necessary to use preventive strategies during coronavirus disease 2019 (COVID‑19) outbreak, which an ongoing global concern. However, critical times in STEMI management may influenced by implementation infection control protocols. Aims: We aimed investigate impact our dedicated COVID‑19 PPCI protocol on time...

Specific infectious agents have been found to be related the pathogenesis of coronary atherosclerosis.We assessed possible association between angiographically proven artery disease (CAD) and hepatitis B surface antibody (HBS Ab) seropositivity in a population with relatively high prevalence virus (HBV) infection.This was cross-sectional study.We analyzed data from 830 consecutive subjects undergoing angiography, including angiographic results reported by two cardiologists for inter-observer...

Background: Performing primary percutaneous coronary intervention (PPCI) in a timely fashion is crucial part of the management ST-elevation myocardial infarction (STEMI). We aimed to evaluate contributing factors and etiologies prolonged door-to-device (D2D) time. Methods: In 2016, D2D time was measured all patients who were treated with PPCI at Tehran Hear Center. The major causes (>90 min) determined. second phase then started 2017 by focusing on determined causes, direct feedback given...

Background: Different percutaneous coronary intervention (PCI) strategies, including the use of single long stents (SLSs) and overlapping multiple (OMSs), have been introduced to treat very lesions (VLCLs). The aim this study was compare procedural long-term clinical outcomes between SLSs OMSs in patients with VLCLs.
 Methods: In historical cohort study, 1709 who underwent PCI new generation drug-eluting (length ≥38 mm) were stratified into SLS [PROMUS /Resolute/XIENCE (PRX), (=38 mm),...

We compared outcomes of percutaneous coronary intervention patients who received biodegradable-polymer biolimus-eluting stents with those durable-polymer everolimus-eluting stents. At Tehran Heart Center, we performed a retrospective analysis the data from January 2007 through December 2011 on 3,270 consecutive artery disease underwent stent or stent. excluded histories bypass grafting intervention, acute ST-segment-elevation myocardial infarction, implantation 2 different types.

Prolactin is correlated with some conditions that predispose individuals to atherosclerosis. receptors have been found in atherosclerotic plaques. However, the correlation between serum prolactin level and extension severity of coronary artery atherosclerosis has yet be studied.In total, 414 postmenopausal women candidated for selective angiography normal levels were enrolled.

Background: Patients with ST-segment elevation myocardial infarction (STEMI) experience major adverse cardiac events (MACEs) following primary percutaneous coronary intervention (PCI). Although the relationship between time to treatment (eg, door-to-balloon time, symptom onset-to-balloon and onset-to-door time) 1-month all-cause mortality was assessed previously, its in-hospital MACEs effect of some clinical characteristics on this were not considered. Furthermore, previous studies that...
