Left inferior wall myocardial infarction

The symptoms of left inferior wall myocardial infarction are very serious diseases, which can cause death in patients. This is mainly because when left inferior wall myocardial infarction occurs, it should affect the blood circulation of the left circulation, which can easily cause hypoxia in patients and myocardial pectoris, etc. Regarding the symptoms of left inferior wall myocardial infarction, we can learn about the following content. If you find this disease, you should seek medical attention immediately.

Symptoms of inferior myocardial infarction

1. Premonition

More than half of the patients have prodromal symptoms such as fatigue, chest discomfort, palpitations during activities, shortness of breath, irritability, and angina pectoris a few days before the onset of the disease. Among them, new onset of angina pectoris and aggravation of existing angina pectoris are the most prominent. Angina pectoris attacks are more frequent than before, and the efficacy of nitroglycerin is poor. People should be alert to the possibility of myocardial infarction.

2. Symptoms

The pain first occurs, mostly in the early morning, and the location and nature of the pain are the same as angina pectoris. However, if the condition is severe and lasts for a long time, rest or nitroglycerin will not work. It may be accompanied by a sense of impending death, and a few people may experience shock or acute heart failure from the beginning.

Systemic symptoms may include fever, tachycardia, increased white blood cell count and increased erythrocyte sedimentation rate. Fever usually occurs 24 to 48 hours after the pain occurs, and the body temperature is usually around 38°C.

Gastrointestinal symptoms may include nausea, vomiting, upper abdominal distension and pain, and in severe cases, hiccups.

Arrhythmias often occur within 1 to 2 weeks of onset, and are most common within 24 hours. Ventricular arrhythmias are the most common, especially premature ventricular contractions. Atrioventricular and bundle branch blocks are also common.

Hypotension and shock Shock usually occurs within a few hours to a week after onset and is mostly cardiogenic.

Heart failure is mainly acute left heart failure. It is caused by weakened myocardial contractility or uncoordinated contraction after infarction.

3. Physical signs

The heart borders are enlarged, the heart rate is fast, the first heart sound at the apex is weakened, the fourth heart sound and gallop rhythm may appear, and there is usually a pericardial friction sound after 2 to 3 days. A rough systolic murmur or a click in the middle and late stages of systole may occur in the apical area, which is caused by dysfunction or rupture of the mitral papillary muscles, and may lead to various arrhythmias.

The above is an introduction to the symptoms of inferior wall myocardial infarction. I believe you can quickly and accurately distinguish it from myocardial infarction. Here I sincerely hope that all patients can get rid of the disease as soon as possible and embrace a healthy body.
