Abstract
Objectives Smoking is a potent risk factor for coronary artery disease, but there is controversy about its protective nature in terms of prognosis in ST-elevation acute coronary syndrome patients undergoing primary percutaneous coronary intervention. So, the main objective of this study is to unfold this controversy in a South Asian population in terms of clinical angiographic parameters and its in-hospital outcomes. Methods In this study, we included 1756 consecutive patients diagnosed with ST-elevation acute coronary syndrome undergoing primary percutaneous coronary intervention. Patients were classified into smokers and non-smokers, and the in-hospital mortality rate was compared. Multivariable logistic regression analysis was performed to evaluate the paradoxical role of smoking. Results Smokers were younger (53.78 ± 11.16 years vs 56.43 ± 11.17 years; p < 0.001) and more frequently men (98.7% vs 69.9%; p < 0.001) and had less diabetes (19.6% vs 44.8%; p < 0.001) and hypertension (38.5% vs 64.9%; p < 0.001). Smokers presented less frequently in Killip III (5.6% vs 8.1%; p < 0.001) and Killip IV (2.5% vs 4.8%; p < 0.001). Smokers mostly had single vessel disease (41.7% vs 34.4%; p = 0.013), whereas non-smokers had the multi-vessel disease and frequently presented with total occlusion of the culprit vessel (64.6% vs 58.8%; p = 0.040). Smokers have significantly lesser mortality (1.8% vs 4.3%; p = 0.009) compared to non-smokers with an odds ratio of 0.41 (95% confidence interval (CI): 0.21-0.82, p = 0.011); however, adjusted odds ratio on multivariable analysis was 0.67 (95% CI: 0.31-1.41, p = 0.290). Conclusions The paradoxical protective role of smoking is the confounding effect of mainly younger age, less coronary artery disease burden, lower prevalence of diabetes and hypertension, and lower Killip III/IV at presentation.

Abstract
The incidence of premature ischemic heart disease (IHD) is increasing because of urbanization, a sedentary lifestyle, and various other unexplored factors, especially in South Asia. This study aimed to assess the distribution of premature ST-elevation acute coronary syndrome (STE-ACS) with its clinical and angiographic pattern along with hospital course in a contemporary cohort of patients who underwent primary percutaneous intervention at a tertiary care center in the South Asian region. We included consecutive patients of either gender diagnosed with STE-ACS and who underwent primary percutaneous intervention. Patients were stratified based on age as ≤40 years (young) and >40 years (old). Clinical characteristics, angiographic patterns, and hospital course were compared between the 2 groups. Of the total of 4,686 patients, 466 (9.9%) were young (≤40 years). Young patients had a lower prevalence of hypertension (40.8% vs 54.5%, p <0.001), diabetes (26.6% vs 36.4%, p <0.001), metabolic syndrome (14.8% vs 24%, p <0.001), history of IHD (5.8% vs 9.3%, p = 0.013) and a higher frequency of smoking (33% vs 24.7%, p <0.001), positive family history (8.2% vs 3.2%, p <0.001), and single-vessel involvement (60.1% vs 33.2%, p <0.001). The composite adverse clinical outcome occurrence was significantly lower in young patients (14.2% vs 19.5%, p = 0.006). On multivariable analysis, history of IHD in young, whereas age, Killip class III/IV, intubated, arrhythmias on arrival, diabetes, history of IHD, pre-procedure left ventricular end-diastolic pressure, ejection fraction <40%, and slow flow/no-reflow during the procedure were found to be the independent predictors of adverse clinical outcome in old patients. In conclusion, we have a substantial burden of premature STE-ACS, mostly in male patients potentially driven by smoking and positive family history. Despite favorable pathophysiology, with mostly single-vessel hospital courses of STE-ACS in the young equally lethal in nature.

Abstract
BACKGROUND The contrast-induced nephropathy (CIN) is a common complication of primary percutaneous coronary intervention (PCI) it has been reported to be associated with an increased risk of mortality. The study reported the in-hospital mortality among patients who developed CIN after primary PCI. METHODS This descriptive cross-sectional study was conducted on a sample of consecutive who developed CIN after primary PCI at a tertiary care cardiac hospital in Karachi, Pakistan. The CIN was defined as either a relative increase of 25% or an absolute increase of 0.5 mg/dL in post -procedure serum creatinine within 72 hours. The in-hospital mortality status was recorded and clinical and demographic predictors of in-hospital mortality were identified with the help of binary logistic regression analysis. RESULTS In the study sample of 402 patients, 74.1% (298) were male and the mean age of the study sample was 59.4±11.5 years. The in-hospital mortality rate was 9.7% (39). On multivar iable analysis, an increased risk of mortality was found to be independently associated with inferior wall myocardial infarction (IWMI) with right ventricular (RV) infarction, intra-procedure arrhythmias, and pump failure with an adjusted odds ratio of 3.63 [95% CI: 1.31-10.08; p=0.013], 5.53 [95% CI: 1.39-22.06; p=0.015], and 8.94 [95% CI: 3.99-20.02; p<0.001], respectively. CONCLUSIONS In conclusion, there is a high rate of mortality for patients who develop CIN after primary PCI, and the risk of mortality is further aggravated by the presence of IWMI with RV infarction, intra-procedure arrhythmias, and pump failure.

Abstract
BACKGROUND Acute hyperglycemia is considered an independent prognosticator of both in-hospital and long-term outcomes in patients with acute coronary syndrome (ACS). This study aimed To analyze the incidence of acute hyperglycemia and its impact on the adverse in-hospital outcome in patients with STE-ACS undergoing primary percutaneous coronary intervention (PCI). METHODS In this study, we enrolled patients presenting with STE-ACS and undergoing primary PCI at a tertiary care cardiac center. Acute hyperglycemia was defined as random plasma glucose (RBS) > 200 mg/dl at the time of presentation to the emergency room. RESULTS Of the 4470 patients, 78.8% were males, and the mean age was 55.52 ± 11 years. In total, 39.4% (1759) were found to have acute hyperglycemia, and of these, 59% (1037) were already diagnosed with diabetes. Patients with acute hyperglycemia were observed to have a higher incidence of heart failure (8.2% vs. 5.5%; p < 0.001), contrast-induced nephropathy (10.9% vs. 7.4%; p < 0.001), and in-hospital mortality (5.7% vs. 2.5%; p < 0.001). On multivariable analysis, acute hyperglycemia was found to be an independent predictor of mortality with an adjusted odds ratio of 1.81 [1.28-2.55]. Multi-vessel disease (1.73 [1.17-2.56]), pre-procedure left ventricular end-diastolic pressure (LVEDP) (1.02 [1.0-1.03]), and Killip class III/IV (4.55 [3.09-6.71]) were found to be the additional independent predictors of in-hospital mortality. CONCLUSIONS Acute hyperglycemia, regardless of diabetic status, is an independent predictor of in-hospital mortality among patients with STE-ACS undergoing primary PCI. Acute hyperglycemia, along with other significant predictors such as multi-vessel involvement, LVEDP, and Killip class III/IV, can be considered for the risk stratification of these patients.
