Aims and objectives Myocardial infarction (MI) remains a leading cause of
mortality and morbidity globally. Timely recognition of symptoms, and
understanding of associated risk factors, are critical for early intervention and
improved outcomes. However, awareness levels - particularly among the elderly in
rural regions - remain poorly studied. This study aimed to assess the awareness
of heart attack symptoms and risk factors among the elderly population in rural
Chennai. Methodology A cross-sectional study was conducted among 384 individuals,
aged 60 years and above, in the rural field practice area of Medavakkam, under
Madras Medical College, Chennai, India. An interviewer-administered questionnaire
assessed knowledge of 9 symptoms and 11 risk factors associated with MI.
Awareness scores were calculated based on participants' spontaneous and prompted
responses. Results The mean age of participants was 65 years. Chest pain (248, or
64.58%) and breathlessness (176, or 45.83%) were the most recognized symptoms,
while neck pain (12, or 3.12%) was the least known. Among risk factors,
hypertension (182, or 47.4%) and stress (178, or 46.35%) were most identified,
whereas high salt intake (22, or 5.73%) and obesity (26, or 6.77%) were least
known. The average awareness score for symptoms was 5.56, for risk factors, 7.61,
and the total knowledge score was 13.18 out of 20. Conclusion The study reveals
significant gaps in awareness of heart attack symptoms and risk factors among the
rural elderly. These findings underscore the urgent need for community-based
health education and preventive strategies, tailored to this vulnerable
demographic, to enhance early recognition and reduce MI-related morbidity and
mortality.
