Introduction: Myocardial infarction (MI)1 is an important disease entity in developed nations and recently in developing nations2 particularly in India in terms of mortality. It usually effects the middle and older age groups. However, recently the incidence in younger individuals is also increasing.

Aims and Objectives: To study the age, sex incidence risk factor and clinical presentation, clinical and laboratory profile, electrocardiography and echocardiographic evidence of patients with myocardial infarction in patients below 40 years. To study the angiographic profile of myocardial infarction in young.

Materials and Methods: This is a cross sectional study conducted upon a sample size of 54 patients.The studygroup consisted of patients aged below 40 years presented with myocardial infarction attending to Department of Cardiology, Mamata General Hospital, Khammam, during the period from October 2019 to March 2020.

Results: Incidence of myocardial infarction increases with increase in age. In our study 68.5% of the patients were in the age group of 35–40 years, in females it was observed that the coronary artery disease started 10 years later than in males and the incidence increases towards menopause. Chest pain was most common symptom followed
by SOB. Hypertension and diabetes were also the associated factors.
Conclusions: Most common age group affected was between 36 to 40 years with most common symptoms being chest pain, common cardiovascular sign was hypertension. Risk factors analyses proved that smoking was the single most important risk factor for myocardial infarction. Majority of patients with myocardial infarction had
dyslipidemia. Family history of myocardial infarction is an important risk factors contributing to myocardial infarction in young individuals.
