Assessment of Coronary Collaterals Among Patients With ST-segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention and its Impact on In-hospital and 30-day Mortality: A Prospective Observational Study.

Objectives: This study aimed to determine the distribution of coronary collaterals (CC) as per the Rentrop Collateral Score (RCS) among patients with ST-segment elevation myocardial infarction (STEMI) and its impact on in-hospital and 30-day mortality after primary percutaneous coronary intervention (PCI).

Methods: In this study, a selected sample of consecutive STEMI patients was assessed for the development of CC as per the RCS classification. An RCS grade of 2 or 3 was taken as the presence of CC with either partial or complete filling of the infarct-related artery (IRA).

CHA DS -VASc score, a simple clinical tool for early prediction of no-reflow phenomenon in patients undergoing emergency percutaneous coronary revascularization.

Slow flow/no reflow (SF/NR) phenomenon during emergency percutaneous revascularization is a feared complication associated with increased risk of adverse outcomes. CHA DS -VASc score has been proposed for the risk stratification but a very limited evidences are available regarding the accuracy of this system. Therefore, we conducted this study to assess the predictive value of CHA DS -VASc score for predicting SF/NR phenomenon during primary percutaneous coronary intervention (PCI).

Safety and Feasibility of Same Day Discharge Strategy for Primary Percutaneous Coronary Intervention.

Background: The strategy for early discharge after primary percutaneous coronary intervention (PCI) could have substantial financial benefits, especially in low-middle income countries. However, there is a lack of local evidence on feasibility and safety of the strategy for early discharge. Therefore, the aim of this study was to assess the safety of early discharge after primary PCI in selected low-risk patients in the population of Karachi, Pakistan.

Radial or femoral access in primary percutaneous coronary intervention (PCI): Does the choice matters?

Background: This study was conducted with the aim of providing a quantitative appraisal of clinical outcomes of trans-radial access for primary percutaneous coronary interventions (PCI) in patients with ST-segment evaluation myocardial infarction (STEMI).

Methods: In this study, we compared two propensity-matched cohorts of patients who underwent primary PCI via trans-radial (TRA) and trans-femoral access (TFA) in a 1:1 ratio. The profile of two cohorts was matched for gender, age, and body mass index, diabetes, hypertension, family history, and smoking.

Ten years risk assessment of atherosclerotic cardiovascular disease using Astro-CHARM and pooled cohort equation in a south Asian sub-population.

Background: Atherosclerotic cardiovascular diseases (ASCVD) are on the rise in low and middle-income countries attributed to modern sedentary lifestyle and dietary habits. This has led to the need of assessment of the burden of at-risk population so that prevention measures can be developed. The objective of this study was to assess ten years risk assessment of ASCVD using Astro-CHARM and Pooled Cohort Equation (PCE) in a South Asian sub-population.

New-onset Atrial Fibrillation in Patients Presenting with Acute Myocardial Infarction.

Background Atrial fibrillation (AF) can be seen secondary to the complications after acute myocardial infarction (AMI), but it has a poor prognosis when occurs independently. These patients are prone to an increased risk of all in-hospital major cardiac complications and also at an increased risk of mortality. Therefore, it is important to quantify the burden of this aggravating complication in an otherwise lethal manifestation of acute coronary syndrome.

Assessment of Femoral Artery Bifurcation Level with Conventional Angiography.

Introduction The common femoral artery (CFA) is the optimal access point for femoral arterial puncture. A higher or lower puncture can result in various vascular complications and by the proper definition of the femoral arterial bifurcation level and the optimal puncture point such complications can potentially be avoided. In the literature, little data is available about the frequency of femoral artery bifurcation and the relationship between the bifurcation level of one artery and its contralateral counterpart in our part of the world.
