Frequency of foot ulcers in people with type 2 diabetes, presenting to specialist diabetes clinic at a Tertiary Care Hospital, Lahore, Pakistan.

Background: Diabetic foot ulceration is a serious limb-threatening complication of diabetes. It is the common cause of hospital admissions and amputations. The objective of the study was to determine the prevalence of diabetic foot ulcers (DFU) and its association with age, gender, duration of diabetes, peripheral neuropathy (PN), peripheral arterial disease (PAD) and HbA1c.

Long-term outcomes of drug-eluting stents versus bare metal stents in saphenous vein graft interventions. Evidence from a meta-analysis of randomized controlled trials.

Background: The optimal stent for use in saphenous vein graft (SVG) intervention is still debatable. Multiple randomized trials have compared drug-eluting stents (DES) to bare metal stents (BMS) in SVG interventions with conflicting results.

Methods: Authors searched the online databases for randomized controlled trials (RCTs) comparing DES to BMS in SVG percutaneous coronary interventions (PCI).

Multivariate Criteria Most Accurately Distinguish Cardiac from Noncardiac Causes of Dyspnea.

Cardiopulmonary exercise testing provides oxygen pulse as a continuous measure of stroke volume, which is superior to other stress-testing methods in which systolic function is measured at baseline and at peak stress. However, the optimal peak oxygen pulse criterion for distinguishing cardiac from noncardiac causes of exercise limitation is unknown. In comparing several peak oxygen pulse criteria against the clinical standard of cardiopulmonary exercise testing, we retrospectively studied 54 consecutive patients referred for cardiopulmonary exercise testing.

Association between alcohol consumption and systolic ventricular function: a population-based study.

Background: Although moderate alcohol consumption is associated with decreased clinical heart failure, there are no population-based studies evaluating the relationship between alcohol consumption and left ventricular (LV) systolic function. We sought to evaluate the relationship between alcohol consumption and LV systolic function in the community.

Methods: In a population-based random sample of 2,042 adults, age ≥45 years, we assessed alcohol consumption by a self-administered questionnaire.
