Comparative StudyNonobstructive coronary disease leading to STEMI: assessment of residual stenosis after thrombus aspiration.
Nonobstructive coronary atherosclerotic lesions can lead to ST-elevation myocardial infarction (STEMI). Thrombus aspiration during a primary percutaneous coronary intervention provides a setting to evaluate the degree of stenosis of culprit lesions leading to STEMI. The aim of this study was to assess the degree of culprit lesion residual stenosis after thrombus aspiration and to compare the demographic, clinical, and angiographic characteristics between patients with obstructive versus nonobstructive residual stenosis. ⋯ In this population, a significant proportion of patients with STEMI had nonobstructive residual stenosis after thrombus aspiration. These patients were younger, had a lower prevalence of vascular disease in other vascular territories, and less multivessel disease, suggesting an earlier stage of atherosclerosis.

Short-term and long-term mortality associated with ventricular arrhythmia in patients hospitalized with acute coronary syndrome: findings from the Gulf RACE registry-2.
Ventricular arrhythmia (VA) in the setting of acute coronary syndrome (ACS) carries an ominous prognosis; however, long-term prognosis associated with VA in ACS in the Middle East is unknown. Accordingly, we sought to assess the incidence, in-hospital outcomes, and 1-year mortality of in-hospital VA in patients with ACS. ⋯ In-hospital VA in patients with ACS with and without ST elevation was associated with significantly higher in-hospital, 30-day, and 1-year mortality. Noticeably higher long-term mortality among Middle Eastern patients with ACS having VA compared with other reports requires further study and warrants immediate attention.

The prognostic value of serum albumin levels on admission in patients with acute ST-segment elevation myocardial infarction undergoing a primary percutaneous coronary intervention.
Hypoalbuminemia is associated with a poor prognosis in patients with end-stage renal disease, chronic ischemic heart disease, heart failure (HF), and stroke. We aimed to investigate its prognostic value in patients with acute ST-segment elevation myocardial infarction (STEMI) treated by a primary percutaneous coronary intervention (p-PCI). ⋯ Hypoalbuminemia on admission is a strong independent predictor for long-term mortality and development of advanced HF in patients with STEMI undergoing p-PCI.
