Silent heart ischemia is a condition characterized by decreased oxygen-rich blood flow in the absence of chest discomfort or other angina symptoms. Silent myocardial infarction (MI) is asymptomatic; it does not cause symptoms like normal myocardial infarction. According to new research, coronary artery disease is common in people with aortic stenosis (AS). Cardiac arrest is a new condition in which a person does not obtain enough oxygen because of an unhealthy lifestyle, dietary habits, cigarette and smoking usage, lack of exercise, sleeping patterns, and other factors that contribute to coronary artery disease. In our research, we acknowledge the pathogenic aspects as well as the diagnostic procedures used to detect myocardial infarction symptoms in our bodies, such as blood tests, CT scans, X-rays, and so on. The death rate in India and other countries is at an all-time high. The therapy is determined by the stage of cardiac arrest, although it is also accomplished with certain preventive medicines and surgical interventions.
