Left ventricular hypertrophy can be categorized as physiologic and pathologic. Physiologic left ventricular hypertrophy is common in athletes and may be asymptomatic. Pathological left ventricular hypertrophy may have no obvious clinical symptoms in the early stage, but in severe cases, there are symptoms such as chest tightness, angina or chest pain, dyspnea, and confusion. Pathologic left ventricular hypertrophy is often accompanied by hypertension or a history of heart disease, and the following typical symptoms often appear: 1. Chest tightness and panic: caused by increased myocardial contractility or elevated left ventricular pressure. 2. Angina or chest pain: myocardial ischemia is aggravated during physical activity or emotional excitement, causing angina or chest tightness. 3. Dyspnea: early manifestation of exertional dyspnea, and in severe cases, nocturnal paroxysmal dyspnea and sedentary breathing may occur. 4. Unconsciousness: when the condition is serious, myocardial ischemia is severe, pumping dysfunction, insufficient blood supply to the brain causing unconsciousness or fainting. It is recommended to seek timely medical treatment for the above symptoms and standardize the treatment under the guidance of doctors.
