Mortality, risk indicators, mode and place of death and symptoms of anginapectoris in the five years after coronary artery bypass grafting in patients with and without a history of hypertension

Aim: To describe mortality, risk indicators for death, place and mode of de ath, and symptoms of angina pectoris among survivors in the 5 years after c oronary artery bypass grafting (CABG) in patients with and without a histor y of hypertension. Methods: All patients in western Sweden who underwent CA BG without concomitant valve surgery and without previously performed CABG between June 1988 and June 1991. Results: A total of 1997 patients were inc luded in the analysis, 740 (37%) of whom had a history of hypertension. Pat ients with no history had a 5-year mortality of 12.4%. The corresponding re lative risk for hypertensives was 1.4 (95% CI 1.1-1.8). Risk factors for de ath appeared similar in patients with and without a history of hypertension . Patients with hypertension had an increased risk of death in hospital and an increased risk of a non-cardiac death. Among survivors after 5 years, p atients with a history of hypertension tended to have a higher prevalence o f symptoms equivalent to angina pectoris. Conclusions: Patients with a hist ory of hypertension have an increased risk of death in the 5 years after CA BG. Risk factors for death appear similar in patients with and without a hi story of hypertension. Patients with hypertension have a particularly incre ased risk of death in hospital and of death judged as non-cardiac.
