Several biologic and clinical factors contribute to the increased 30-day mortality and re-infarction rate in women with ST-segment elevation myocardial infarction (STEMI). Sex differences in cardiac hemodynamic parameters such as pulmonary capillary wedge pressure (PCWP) have not been examined and might play an important role. The objectives of the present(More)
BACKGROUND This study was undertaken to determine the prevalence of coronary artery disease in patients with rheumatic heart disease undergoing valve surgery. METHODS AND RESULTS Consecutive patients with rheumatic heart disease (n=376) who were above the age of 40 years, and scheduled for valve surgery underwent diagnostic coronary angiogram to delineate(More)
A 23-year-old female patient with type III nonspecific aortoarteritis (Takayasu's arteritis) presented with multiple obstructive lesions and severe congestive heart failure. Large, cutting balloons 5-8 mm in diameter were used to dilate lesions in the abdominal aorta, both renal arteries, right common carotid artery, proximal left subclavian artery, and(More)
MATERIALS AND METHODS Two hundred patients at steady-state on long-term perhexiline were identified retrospectively. The ratio of maintenance dose to steady-state plasma concentration (dose:[Px]) was correlated with the following putative determinants via simple and multiple linear regression analyses: age, weight, left ventricular ejection fraction (LVEF),(More)
BACKGROUND A delayed Door-to-Balloon (DTB) time in women with ST-elevation myocardial infarction (STEMI) has been associated with an increased mortality. The objectives of this study were to (a) quantify the components of the delayed DTB time in women and (b) assess the independent effect of gender on DTB time in patients undergoing percutaneous coronary(More)
BACKGROUND Clopidogrel has become the standard antiplatelet drug along with aspirin in patients undergoing coronary angioplasty; however, data regarding the nonresponse rate to clopidogrel therapy in Indian patients are limited. METHODS AND RESULTS Platelet aggregation was measured at baseline and 2 and 24 hours post administration of bolus dose of 300 mg(More)
The over-the-wire double balloon technique (DBT) of balloon mitral valvuloplasty (BMV) has been decreasingly used in recent years because of its relative complexity and potential for left ventricular perforation. We attempted to make over-the-wire BMV simpler and safer by developing: (a) a single balloon technique (SBT) using a rapidly inflating,(More)
BACKGROUND There is widespread concern about radiation doses imparted to patients during cardiology procedures in the medical community. The current study intends to audit and optimize radiation dose to patients undergoing coronary angiography (CA) performed using two dedicated cardiovascular machines. MATERIALS AND METHODS One hundred and forty nine(More)
