Final answer:
The symptoms described suggest a possible diagnosis of angina pectoris. Tests such as ECG, exercise stress testing, and coronary angiography can confirm the diagnosis.
Step-by-step explanation:
The symptoms described, progressive epigastric pain especially post prandial and signs and symptoms of atherosclerotic disease, suggest a possible diagnosis of angina pectoris. Angina pectoris is a form of chest pain that occurs when the heart muscle doesn't get enough blood and oxygen due to narrowed or blocked coronary arteries. It is typically triggered by physical exertion or emotional stress and may subside with rest or nitroglycerin.
To confirm the diagnosis, several tests can be performed. Electrocardiography (ECG) can show characteristic changes suggestive of myocardial ischemia or a heart attack. Exercise stress testing can be done to induce angina symptoms and observe changes in heart function. Coronary angiography involves injecting a contrast dye into the coronary arteries to visualize any blockages or narrowing.
