The most common causes of heart like cramps are angina or myocardial infarction, intercostal neuralgia, rib fractures in the precordial area, pleurisy, and other diseases, as summarized below. 1. Angina pectoris or myocardial infarction Angina pectoris or myocardial infarction occurs when the coronary arteries are narrowed due to coronary atherosclerosis, which reduces or interrupts the blood flow, and can be manifested as a cramp in the heart or a tightness in the precordial area, which requires emergency treatment. 2. Intercostal neuralgia Intercostal neuralgia can be left behind due to herpes zoster virus infection, which involves intercostal neuropathy in the precordial area. The heart feels like a cramp during an attack. 3. Pre-cardiac rib fracture Fractures of the ribs in the precordial area due to trauma or other factors will cause pain similar to heart cramps, especially when breathing deeply. 4. Pleurisy Inflammation of the pleura, especially in the precordial area, due to infectious or non-infectious factors, can cause a cramping sensation in the heart. 5. Other factors Heart cramps can also occur when there is muscle damage in the precordial area, cardiac neurosis and other factors. In short, there are many reasons that can cause the heart to feel like a cramp, and it is necessary to consult the hospital in time to clarify the cause of the disease and treat the cause of the disease.
