Hypertension and myocardial infarction
Insights
Hypertension affects 36% of male myocardial infarction survivors. While not impacting mortality, hypertension significantly increases the risk of non-fatal reinfarction within two years post-heart attack.
Area of Science:
- Cardiology
- Clinical Medicine
- Public Health
Background:
- Hypertension is a common comorbidity in patients following a first myocardial infarction (MI).
- Understanding the long-term impact of hypertension on post-MI prognosis is crucial for patient management.
Purpose of the Study:
- To determine the prevalence of hypertension in male patients after a first MI.
- To investigate the influence of hypertension on the prognosis, including reinfarction and mortality, over a 2-year follow-up period.
Main Methods:
- A cohort of 504 male patients surviving their first MI was studied.
- Hypertension was defined based on pre-existing diagnosis or detection post-MI.
- Data on mortality and non-fatal reinfarction were collected over 2 years, with adjustments for confounding factors.
Main Results:
- Hypertension was prevalent in 36% of the male MI patient cohort.
- No significant difference in overall death rate was observed between hypertensive and non-hypertensive groups.
- Hypertensive patients exhibited a significantly higher rate of non-fatal reinfarction.
- Hypertension remained an independent risk factor for adverse outcomes after MI, even after accounting for lipids and smoking.
Conclusions:
- Hypertension is a significant factor in male patients post-myocardial infarction.
- Managing hypertension is critical to reduce the risk of recurrent cardiovascular events, specifically non-fatal reinfarctions.
Abstract:
In a representative series of male patients (n = 504) surviving the hospital stay of a first myocardial infarction the prevalence of hypertension and the influence of hypertension on the prognosis during 2 yr follow-up were studied. According to the definitions used hypertension had been detected before or was detected after myocardial infarction in 36% of the patients. Two thirds had a history of hypertension known before infarction. The systolic and diastolic blood pressures measured at 3 months and 1 yr after infarction increased with age. There was no difference between patients with and without hypertension with respect to a number of different variables recorded during the hospital period, nor in multiple risk according to a logistic function. There was no difference in death rate between the two groups. However, the rate of non-fatal reinfarction was significantly higher among the hypertensive patients. Hypertension remained as a risk factor for after myocardial infarction when the possible confounding influences of serum lipid levels and tobacco smoking were analysed.
