- 2. INTRODUCTION • Myocardial infarction(MI) also known as a heart attack can be defined as cell death of cardiac myocytes caused by ischemia, which is the result of a perfusion imbalance between supply and demand. • According to World Health Organisation (WHO), cardiovascular diseases (CVDs) are the leading cause of death globally, taking an estimated 17.9 lives each year (https://www.who.int/). • Indians are known to have the highest coronary artery disease (CAD) rates. According to the survey in 2020, the Global Burden of Disease study stated that the IHD death rate per 100000 population in India is 272 which is much higher than the global average of 235.

- 4. TYPES OF MYOCARDIALINFARCTION TYPE 1 Spontaneous myocardial infarction related to ischaemia due to a primary coronary event such as plaque erosion and/or rupture, fissuring, or dissection. TYPE 2 Myocardial infarction secondary to ischaemia due to either increased oxygen demand or decreased supply, e.g. coronary artery spasm, coronary embolism, anaemia, arrhythmias, hypertension, or hypotension. TYPE 3 Sudden unexpected cardiac death, including cardiac arrest. TYPE 4 TYPE 4A Myocardial infarction associated with PCI. TYPE 4B Myocardial infarction associated with stent thrombosis as documented by angiography or at autopsy. TYPE 5 Myocardial infarction associated with CABG.
