BACKGROUND Very little has been published on Filipino (F) or Filipino-American (FA) health. Nothing has been written about coronary risk factors and their relationship to outcomes of percutaneous coronary intervention or cardiac surgical treatment in this group. The purpose of this study was to analyze prospectively collected data at a center treating(More)
OBJECTIVES Bilateral internal mammary arteries (BIMA) remains widely underutilized in coronary artery bypass grafting (CABG). Although prior research has demonstrated a long-term benefit of the use of BIMA over left internal mammary artery (LIMA)-only, validation of these results is lacking in a contemporary surgical experience. We compared complications(More)
Clopidogrel is an oral antiplatelet pro-drug prescribed to 40 million patients worldwide who are at risk for thrombotic events or receiving percutaneous coronary intervention (PCI). However about a fifth of patients treated with clopidogrel do not respond adequately to the drug. From a cohort of 105 patients on whom we had functional data on clopidogrel(More)
BACKGROUND Stroke remains an important complication after coronary artery bypass graft surgery (CABG). We sought to determine the frequency and death-related incidence of stroke after on-pump and off-pump CABG. METHODS We analyzed 4,869 consecutive isolated CABG performed in our institution. Of these, 3,490 (71.7%) were off-pump and 1,379 (28.3%) were(More)
OBJECTIVES Recent studies have demonstrated the superiority of bilateral internal mammary arteries (BIMAs) as conduit material for coronary artery bypass grafting (CABG) surgery. However, there is limited research on the effects of other graft conduits used in patients who require additional bypasses. The goal of this study was to evaluate the impact of the(More)
BACKGROUND The current standard of care is to delay coronary surgery 5-7 days after clopidogrel exposure to prevent bleeding complications. We sought to determine the utility of an objective tool (ie, the VerifyNow assay) to measure platelet inhibition (PI) in patients receiving preoperative clopidogrel prior to off-pump coronary artery bypass grafting(More)
BACKGROUND Studies have found that cardiac surgery patients receiving blood transfusions are at risk for increased mortality during the first year after surgery, but risk appears to decrease after the first year. This study compared 5-year mortality in a propensity-matched cohort of cardiac surgery patients. STUDY DESIGN AND METHODS Between July 1, 2004,(More)
OBJECTIVES Prior studies have found that cardiac surgery patients receiving blood transfusions are at risk for increased mortality and morbidity following surgery. It is not clear whether this increased risk occurs across all haematocrit (HCT) levels. The goal of this study was to compare operative mortality in propensity-matched cardiac surgery patients(More)
Several procedures have been developed to obtain decompression of protal hypertension for bleeding esophageal varices. In recent years, the distal splenorenal shunt has become popular becuase it causes less encephalopathy than the standard portacaval or mesocaval shunts. A criticism of the distal splenorenal shunt has been the technical difficulty of(More)
