Mortality, risk indicators, mode and place of death and symptoms of angina pectoris in the five years after coronary artery bypass grafting in patients with and without a history of hypertension.
OBJECTIVE
To describe mortality, risk indicators for death, place and mode of death, and symptoms of angina pectoris among survivors in the 5 years after coronary artery bypass grafting (CABG) in patients with and without a history of hypertension.


METHODS
All patients in western Sweden who underwent CABG without concomitant valve surgery and without previously performed CABG between June 1988 and June 1991.


RESULTS
A total of 1997 patients were included in the analysis, 740 (37%) of whom had a history of hypertension. Patients with no history had a 5-year mortality of 12.4%. The corresponding relative risk for hypertensives was 1.4 (95% CI 1.1-1.8). Risk factors for death 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, patients with a history of hypertension tended to have a higher prevalence of symptoms equivalent to angina pectoris.


CONCLUSIONS
Patients with a history of hypertension have an increased risk of death in the 5 years after CABG. Risk factors for death appear similar in patients with and without a history of hypertension. Patients with hypertension have a particularly increased risk of death in hospital and of death judged as non-cardiac.
