Sudden heart disease primarily refers to the sudden onset of acute myocardial infarction. Between 50% to 81.2% of patients have prodromal symptoms, experiencing significant chest discomfort, fatigue, palpitations during activity, shortness of breath, irritability, and angina in the days before the onset, with the most prominent being new or worsening angina. The angina is more frequent than before, more severe, lasts longer, and nitroglycerin relief is not significantly apparent; the triggers are also unclear. Sometimes, gastrointestinal symptoms such as nausea, vomiting, and upper abdominal bloating occur and are often misdiagnosed, causing delays in treatment.

How long does heart disease generally hurt?

1. Chest pain caused by angina due to coronary heart disease is located in the middle to lower third of the sternum, with unclear boundaries. It is often triggered by physical activities or emotional excitement and may radiate to the throat, lower jaw, left shoulder, and inner side of the left arm. The pain lasts for a few minutes to more than ten minutes, typically between three to five minutes, and rarely exceeds half an hour. It can be relieved by rest or by taking nitroglycerin under the tongue. The nature of the pain is feelings of stuffiness, pressure, or constriction, and may also feel like a burning sensation, but is not sharp like needle pricks or cuts. 2. The location and nature of the chest pain in acute myocardial infarction are the same as with angina, but it lasts longer, is more severe, and its triggers are less evident. It can occur even while at rest, accompanied by symptoms such as sweating, nausea, vomiting, heart palpitations, and difficulty breathing. Unlike with angina, regular rest or taking nitroglycerin under the tongue does not completely alleviate the pain.

Complications of heart disease

Heart disease is a very common illness in our daily lives. What are the complications of heart disease? The category of heart diseases is broad; here we will discuss some common ones, such as coronary heart disease. Patients with coronary heart disease are prone to develop heart failure, leading to symptoms such as shortness of breath and difficulty breathing, or atrial fibrillation. Atrial fibrillation often leads to complications like thrombosis. For instance, a dislodged thrombus can cause a cerebral infarction, resulting in symptoms like hemiplegia, weakness in one side of the body, and speech disturbances. Additionally, certain severe myocardial diseases can lead to malignant arrhythmias, causing sudden death in patients, which is often very serious.

Which place is the best for a heart disease massage?

Premature cardiac contractions can occur in normal individuals. For younger people, fewer than 3 contractions per minute generally poses no issue, whereas for older individuals, fewer than 5 per minute is considered normal. However, it is recommended to conduct a 24-hour Holter monitor test. If this test shows more than 10,000 occurrences in 24 hours, it is advisable to consult a specialist to determine if medication or hospital treatment, such as radiofrequency ablation, is needed. Additionally, it is crucial to investigate the causes of premature cardiac contractions. If serious diseases are ruled out, it may be helpful to massage corresponding acupoints. Generally, massaging acupoints like the Neiguan and Hegu, which are associated with the kidney and heart meridians, is suggested. Massage of the Fuxi acupoint is also recommended; located at the front of the thigh, it is easier to massage when seated with the knee bent at a 90-degree angle.

How to relieve vomiting caused by heart disease?

Treatment for vomiting caused by heart disease must depend on its cause. First, if caused by heart failure, as the symptoms of heart failure worsen, including right-sided heart failure, patients may experience nausea, vomiting, and bloating after eating. The key in these cases is to correct heart failure, perhaps with intravenous diuretic medications or the newer diuretic drug tolvaptan, which can alleviate symptoms of vomiting caused by heart failure. Secondly, digoxin toxicity can cause vomiting if patients with heart failure are taking too much or have been on digoxin for a prolonged period. The primary action in these instances is to discontinue the digoxin medication promptly. Thirdly, if associated with gastritis, treatment would involve medications to stop vomiting and oral omeprazole to protect the stomach lining. (Medications should be taken under medical supervision.)

Is rheumatic heart disease serious?

Rheumatic heart disease is a type of organic heart disease caused by an abnormal immune response, leading to pathological changes in the heart valves, which pose significant risks to the body. Due to valve insufficiency or stenosis, rheumatic heart disease causes changes in hemodynamics, leading to heart failure and pulmonary edema. These are severe conditions for patients and require timely treatment and correction. If effective dietary therapy is not administered, especially for pulmonary edema, it can be life-threatening.
