Prognosis of Percutaneous Intervention of a Left Main Coronary Artery Stenosis Without the Use of Intravascular Imaging.

Objectives The aim of this study was to assess the prognosis in patients with left main coronary artery stenosis one year after percutaneous coronary intervention (PCI). Methods Our study included 40 patients who underwent PCI for left main coronary artery stenosis without the use of intravascular ultrasound (IVUS). Patients were followed for a year, and the prognostic effect of PCI on a composite end-point of revascularization, new myocardial infarction, cardiac death, and on all-cause mortality was assessed in multivariable Cox analysis.

Endovascular treatment of a post catheterization pseudoaneurysm: A stitch in time saves nine.

External iliac artery (EIA) pseudoaneurysms are a well-known complication after arterial catheterization procedures. Most develop as a result of high femoral puncture. Small asymptomatic pseudoaneurysms are usually of no consequence but large symptomatic pseudoaneurysm carries a significant risk of rupture with serious life-threatening consequences and needs to be treated.

Comparison of the TIMI and the GRACE risk scores with the extent of coronary artery disease in patients with non-ST-elevation acute coronary syndrome.

Objective: To compare the accuracy of the Global Registry of Acute Coronary Events risk score and the Thrombolysis In Myocardial Infarction risk score in predicting the extent of coronary artery disease in patients with non-ST segment elevation acute coronary syndrome.

Methods: The cross-sectional study comprising 406 consecutive patients was conducted at the National Institute of Cardiovascular Diseases, Karachi, from August 2010 to March 2011. For all patients, the GRACE and TIMI RS's relevant scores on the two indices were calculated on admission using specified variables.

Abdominal obesity pattern among various ethnic groups presenting with acute coronary syndrome.

Background: Abdominal obesity is an increasing public health problem and is associated with a number of cardiovascular risk factors. The aim of this study was to determine the frequency of abdominal obesity and associated risk factors in patients of various ethnic groups presenting with acute coronary syndrome.

Methods: A total of 477 patients presenting with acute coronary syndrome to the National Institute of Cardiovascular Diseases, Karachi were studied.
