Autopsy-based morphometric study of coronary atherosclerosis in young adults

Area of Science:

• Cardiovascular Pathology
• Public Health
• Forensic Medicine

Background:

• Cardiovascular diseases pose a significant health burden in Kerala, India.
• A notable proportion of these diseases affect young individuals.
• Autopsy studies are crucial for understanding disease prevalence in specific demographics.

Purpose of the Study:

• To assess the severity of atherosclerosis in individuals under 40 years of age.
• To analyze coronary artery pathology in victims of accidental and suicidal deaths.
• To establish baseline data for cardiovascular disease prevention in young populations.

Main Methods:

• Examination of coronary arteries from 77 autopsies of individuals under 40.
• Grading of atherosclerotic lesions using the American Heart Association (AHA) classification.
• Measurement of degree of stenosis, intimal thickness index (ITI), and intima-media ratio (IMR).

Main Results:

• Advanced atherosclerotic lesions (AHA types 3-6) were found in 55.4% of males and 25% of females.
• Significant coronary artery stenosis (>40%) was observed in 76.6% of cases.
• Stenosis, ITI, and IMR were strongly associated with male sex, overweight, and smoking.

Conclusions:

• The study reveals a high degree of atherosclerotic narrowing in the coronary arteries of young individuals.
• These findings indicate a substantial risk for the community if preventive measures are not implemented.
• Early detection and intervention strategies are critical for mitigating future cardiovascular events.
