over the chest in addition to sweating, nausea, vomiting, and weakness. Chest pain is more commonly associated with anterior infarction because of left ventricular Chest pain is pain or discomfort in the chest, typically the front of the chest. It may be described as sharp, dull, pressure, heaviness or squeezing. Associated symptoms may include pain in the shoulder, arm, upper abdomen, or jaw, along with nausea, sweating, or shortness of breath. It can be divided into heart-related and non-heart-related pain. Pain due to insufficient blood flow to the heart Acute coronary syndrome Stable or unstable angina Myocardial infarction ("heart attack"): People typically present with pressure or squeezing sensation over the chest in addition to sweating, nausea, vomiting, and weakness. Chest pain is more commonly associated with anterior infarction because of left ventricular impairment; inferior infarction is more commonly associated with nausea, vomiting, and excessive sweating due to irritation of vagus nerve; lateral infarction is associated with left arm pain. Prinzmetal's angina: Chest pain is caused by coronary vasospasm. It is more common in women younger than 50 years and has associations with tobacco, cocaine, or triptan use. People usually complain of chest pain at rest that is unrelated to stress or exertion. It is often relieved by cessation of the offending drug and the administration of nitrates or calcium channel blockers. Cocaine use: This condition is suspected when people with few risk factors for arteriosclerosis present with non-traumatic chest pain. Ingestion of cocaine can lead to vasoconstriction of coronary arteries, thus producing chest pain similar to heart attack. Symptoms can appear within one hour of cocaine use. Aortic stenosis: This condition occurs in individuals with underlying congenital bicuspid valve, aortic sclerosis, or a history of rheumatic fever. Chest pain usually happens during physical activity. Syncope is a late symptom. Signs and symptoms of heart failure may also be present. On auscultation, a loud ejection systolic murmur can be heard at the right second intercostal space with radiation to the carotid artery in the neck. Splitting of second heart sound is heard in severe stenosis. Hypertrophic cardiomyopathy: It is the hypertrophy of interventricular septum that causes outflow obstruction of the left ventricle. Dyspnea and chest pain commonly occur during daily activities. Syncope may also…
