The first hypothesis is that restoration of blood flow by means of coronary revascularization recovers chronic LV dysfunction and improves survival, as compared to intensive medical therapy alone. STICH is a multicenter, international, randomized trial that addresses two specific primary hypotheses in patients with clinical heart failure (HF) and left ventricular (LV) dysfunction who have coronary artery disease amenable to surgical revascularization. This study is designed to provide a solid answer. Thus, the choice of medical therapy versus bypass surgery for patients with congestive heart failure and obstructive coronary disease is usually decided by guesswork. In addition, medical therapy for congestive heart failure has improved dramatically over the past two decades. While observational data from the 1970s and early 1980s suggest a survival advantage associated with bypass surgery in patients with low ejection fraction and congestive heart failure, biases favoring the referral of the fittest of such patients for bypass surgery may have confounded these comparisons. In addition, patients with ejection fractions below 35% were specifically excluded from the three large randomized studies of medical therapy versus bypass surgery. ![]() Randomized studies of medical therapy versus bypass surgery for obstructive coronary disease were conducted in the 1970s and did not include the systematic use of aspirin, arterial conduits, or lipid-lowering medications. Surprisingly little is known about the relative benefits of medical versus surgical therapy for patients with obstructive coronary disease and congestive heart failure. ![]() Most cases of congestive heart failure are due to CAD. Why Should I Register and Submit Results?Ĭongestive heart failure afflicts approximately five million Americans and is the leading cause of hospitalization in Americans over the age of 65.
