Family history is a major risk factor for myocardial infarction (MI). However, known gene variants associated with MI cannot fully explain the genetic component of MI risk. We hypothesized that a gene-centric association study that was not limited to candidate genes could identify novel genetic associations with MI. We studied 11,053 single-nucleotide(More)
OBJECTIVES The purpose of this study was to identify genetic variants associated with severe coronary artery disease (CAD). METHODS AND RESULTS We used 3 case-control studies of white subjects whose severity of CAD was assessed by angiography. The first 2 studies were used to generate hypotheses that were then tested in the third study. We tested 12,077(More)
Our previous genomewide linkage scan of 428 nuclear families (GeneQuest) identified a significant genetic susceptibility locus for premature myocardial infarction (MI) on chromosome 1p34-36. We analyzed candidate genes in the locus with a population-based association study involving probands with premature coronary artery disease (CAD) and/or MI from the(More)
Coronary artery disease (CAD), including its most serious complication myocardial infraction (MI), is the leading cause of death in the US and developed countries. We recently discovered that a seven-amino acid deletion in MEF2A, a transcription factor with a high level of expression in the endothelium of coronary arteries, co-segregates with CAD/MI in one(More)
Saphenous veins grafts (SVGs) continue to be used as conduits for coronary bypass surgery in nearly 350,000 patients annually in the United States. A possible genetic contribution to SVG longevity has not been well studied. We analyzed 168 single nucleotide polymorphisms from 150 candidate genes in 155 patients (2.1 SVGs/patient) followed for 10 +/- 4 years(More)
