Prior to myocardial infarction, chest constriction stands as the most characteristic symptom. However, statistical data also reveals that over one-third of patients in my country, afflicted with acute myocardial infarction and angina pectoris, manifest atypical pain symptoms, with approximately one-fifth displaying no pain symptoms whatsoever. Regardless of the presence or absence of symptoms, telltale signs will invariably emerge as a myocardial infarction approaches. Discerning and apprehending these signs offer patients the optimal chance for survival. We now encapsulate various manifestations that may manifest prior to a myocardial infarction to serve as a reminder to readers to remain attentive.
1. Chest discomfort: Cardiac-related chest pain typically localizes beneath the sternum, and the American Heart Association cautions that the archetypal indication of a heart attack encompasses sensations of pressure, constriction, or anguish in the chest, persisting for a duration surpassing two minutes. Individuals with a history of heart disease should exercise heightened vigilance when encountering acute chest pain. Should the duration exceed 15 minutes, immediate medical assistance by dialing 120 is imperative.
2. Dorsal pain: Angina pectoris induced by heart disease elicits radiating pain that disseminates to the lower or upper back. This pain typically stems from clear triggers such as fatigue, tension, or emotional arousal. Its duration is transient, and relief can be attained through rest or the administration of nitroglycerin. Back pain is more prevalent among females, necessitating heightened vigilance when experiencing intense and brief back pain.
3. Abdominal ache: Abdominal pain arising from cardiac problems, termed cardiogenic abdominal pain, is susceptible to misdiagnosis. In cases of unexplained abdominal pain, or pain experienced during physical exertion that marginally subsides at rest, myocardial ischemia or alternative conditions should be investigated.
4. Arm or shoulder pain: Should an abrupt onset of unusual pain and numbness manifest in the arm or shoulder, accompanied by chest pain or a constricting sensation, a heart attack may be underway. When the affliction takes hold, chest pain radiates to the shoulders and arms. Men may experience pain in the left arm, while women may encounter pain in the arm or between the shoulder blades. The pain can range from mild to severe.
5. Hair loss or leg heaviness: Research has unearthed that the loss of leg hair may constitute an inconspicuous symptom of a heart attack. The appearance of plaque in human arteries diminishes blood flow to the lower extremities, impeding adequate nourishment to the hair, resulting in smooth and cool skin on the legs. Patients may perceive heaviness and numbness in their legs whilst walking.
1. Severe headache: Should an unbearable headache persist even after rest, vigilance toward a heart condition is warranted. Headaches are frequently attributed to blood clots within the cardiovascular and cerebrovascular vessels, resulting in inadequate blood supply to the brain. Alternatively, elevated blood pressure may also be a causative factor. When accompanied by symptoms such as vomiting and dizziness, immediate medical attention is imperative.
2. Dizziness: In patients afflicted with myocardial infarction, rupture and subsequent thrombus formation in coronary atherosclerotic plaques can induce occlusion of the coronary arteries supplying the myocardium. This, in turn, can lead to reduced myocardial contractility, arrhythmia, hypotension, and insufficient blood supply to the brain, thereby precipitating dizziness and even syncope.
3. Blurred vision: A minority of patients suffering from myocardial infarction may indirectly experience compromised blood flow in the retinal arteries, resulting in rapid and severe vision loss.
4. Throat tightness: Persistent sensations of tightness or pain in the throat may herald an impending heart attack, necessitating a prompt visit to a cardiology department.
1. Fatigue: Cardiac dysfunction and autonomic nerve dysfunction, stemming from myocardial infarction, may engender intestinal bleeding in patients. Ischemia and hypoxia can further elicit bodily weakness, akin to the symptoms of a severe cold.
2. Gastrointestinal disturbance: In the absence of consuming contaminated food, the presence of diarrhea, nausea, and the inability to vomit indicate escalating stomach discomfort, potentially indicative of a myocardial infarction.
3. Anxiety and insomnia: Unexplained anxiety in the absence of prior instances of insomnia or precipitating factors warrants consideration as a potential sign of myocardial infarction. This form of insomnia differs from ordinary sleeplessness, as it entails abrupt awakenings during the night, accompanied by an overwhelming and inexplicable sense of fear.
4. Breathing difficulties: Besides asthma and chronic obstructive pulmonary disease, cardiac issues such as unstable angina and severe heart failure can result in respiratory distress. Even slight exertion, coupled with a persistent shortness of breath, indicates insufficient blood supply to the heart. Concurrent chest pain should elAlso, you should be highly vigilant as it may indicate a myocardial infarction.
5. Increased heart rate: Should the heart rate suddenly accelerate without any discernible trigger, persisting for a duration of 1 to 10 minutes, particularly after physical activity, emotional arousal, or overeating.
