In 2005, the SYNTAX score was reported as "an angiographic tool grading the complexity of coronary artery disease". We investigated risk factors for the complexity of coronary artery disease (CAD) using SYNTAX scores in patients with new-onset CAD. The subjects were 359 consecutive cases that underwent de novo percutaneous coronary intervention (PCI) or(More)
We discuss the case of a 61-year-old male patient with hypertrophic cardiomyopathy and chest pain on exertion. Coronary angiography and intravascular ultrasound revealed an intermediate stenosis in the proximal site of the left anterior descending artery, while Tc-99m myocardial scintigraphy revealed exercise-induced myocardial ischemia in the anteroseptal(More)
We investigated changes of the complexity of coronary artery disease (CAD) after drug-eluting stent (DES) implantation using SYNTAX score and the predictor of worsened SYNTAX score at follow-up. 116 consecutive patients who underwent de novo PCI with first-generation DES were enrolled. SYNTAX scores were obtained from coronary angiography before PCI, just(More)
