[Ischemic heart disease mortality of men 40 to 59 years old and its basic risk factors (based on prospective study
Insights
This study followed 526 males aged 40-59 with ischemic heart disease (IHD). Hypercholesterolemia was the primary risk factor for increased IHD mortality, which was significantly higher in diagnosed patients.
Area of Science:
- Cardiovascular Medicine
- Epidemiology
- Public Health
Context:
- Investigated mortality rates in middle-aged males with ischemic heart disease (IHD).
- Followed 526 male patients aged 40-59 with IHD over 3.8 years.
- Included detailed health data from 475 patients: anthropometry, blood lipids, and smoking habits.
Purpose:
- To analyze mortality patterns in ischemic heart disease patients.
- To identify key risk factors contributing to IHD mortality.
- To compare mortality between diagnosed IHD patients and the general male population.
Summary:
- Mortality rates from all causes and IHD increased with age in the studied male cohort.
- Patients with myocardial infarction or angina pectoris showed significantly higher mortality.
- Hypercholesterolemia was identified as the sole significant risk factor for elevated IHD mortality.
Impact:
- Diagnosed IHD patients experienced a 7-fold higher mortality rate compared to those without IHD.
- Findings highlight the critical role of managing hypercholesterolemia to reduce cardiovascular mortality.
- Emphasizes the importance of early detection and intervention for ischemic heart disease.
Abstract:
An analysis is presented of a follow-up study during 3.8 years of 526 patients (males aged 40--59 years) with ischaemic heart disease found among 3908 examined males, including 475 patients who were investigated according to full program (anthropometry, determination of total blood cholesterol, triglycerides, alpha-cholesterol, smoking habits). Mortality of patients with IHD aged 40--59 years per 100 patients was: from varying causes--3.1 from ischaemic heart disease 1.55, the figures increasing with age. Mortality from IHD and total in patients who had myocardial infarction with corresponding changes of the ECG and angina pectoris of effort was 3- and 2-fold higher, respectively, than in other forms of the disease. These figures are practically identical in patients with other forms of ischaemic heart disease. Among the main factors of risk only hypercholesterolaemia contributes to increased mortality from IHD. Among patients with IHD detected during investigation lethal cases are 7-fold more frequent than among those without IHD.
