Survival of diabetic hypertensive patients
Insights
Diabetic patients with hypertension had poorer survival rates than expected over 10 years, with acute myocardial infarction being the leading cause of death in both diabetic and nondiabetic hypertensive individuals.
Area of Science:
- Cardiology
- Endocrinology
- Public Health
Background:
- Hypertension and diabetes mellitus are significant cardiovascular risk factors.
- Understanding the combined impact of hypertension and diabetes on survival is crucial for patient outcomes.
Purpose of the Study:
- To compare the survival rates of patients with both diabetes and hypertension to matched control groups.
- To identify the primary causes of mortality in hypertensive patients with and without diabetes.
Main Methods:
- A cohort of 79 diabetic hypertensive patients was identified from an outpatient clinic.
- Age- and sex-matched control groups of nondiabetic hypertensives and the general population were established.
- Survival was observed over a 10-year period, with causes of death recorded.
Main Results:
- Nondiabetic hypertensive patients showed significantly poorer survival than expected.
- Diabetic hypertensive patients exhibited even poorer survival, though not statistically significant compared to nondiabetic hypertensives.
- Acute myocardial infarction was the most common cause of death (40% in diabetics, 42% in nondiabetics).
Conclusions:
- The combination of diabetes and hypertension appears to negatively impact survival.
- Further research is warranted to confirm the significant impact of co-existing diabetes on hypertensive patient survival.
- Acute myocardial infarction is a major cause of mortality in hypertensive individuals, regardless of diabetic status.
Abstract:
Seventy-nine of 673 patients attending a hypertensive outpatient clinic were classified as diabetics at the first examination. These patients were age- and sex-matched to two control groups: nondiabetic hypertensives and the background population. Nondiabetic hypertensive patients had a significantly poorer survival than expected during a 10-year observation period; the survival of diabetic hypertensives was even poorer, although not significantly. No sex difference was observed in the survival rates of hypertensive diabetics, neither was a difference seen between insulin-dependent and non-insulin-dependent patients. Acute myocardial infarction was the most frequent cause of death in both diabetic (40%) and nondiabetic (42%) hypertensive persons.
