What are the symptoms of myocardial infarction and heart failure?
Myocardial infarction generally refers to acute myocardial infarction, while heart failure usually means congestive heart failure. These are two distinct diseases with differing symptoms, and further examination and treatment at a hospital are necessary.
Acute myocardial infarction typically presents with severe angina symptoms, such as chest tightness and chest pain, accompanied by restlessness, rapid or irregular heartbeat, dizziness, sweating, upper abdominal pain, shortness of breath, nausea, and vomiting. Some patients may develop fever within 24 to 48 hours after the onset of pain, and severe cases can lead to shock or sudden death.
In the early stages of heart failure, common symptoms include easy fatigue, shortness of breath during physical activity, palpitations, generalized weakness, and dizziness. As the disease progresses, congestion in the lungs and various organs may occur, causing shortness of breath, coughing, and wheezing even at rest. Most patients also develop dependent edema, particularly swelling in the legs, ankles, and feet. In severe cases, pleural effusion (fluid in the chest), ascites (fluid in the abdomen), or even acute pulmonary congestion may occur, posing a life-threatening risk.
