Introduction
In general, cardiac arrest may be caused by extreme emotional fluctuations, unhealthy lifestyle habits, excessive exercise, coronary atherosclerotic heart disease, acute myocardial infarction, etc. It is important to maintain a healthy lifestyle, avoid overexertion and emotional fluctuations, exercise regularly, and maintain good dietary habits.

In general, cardiac arrest may be caused by extreme emotional fluctuations, unhealthy lifestyle habits, excessive exercise, coronary atherosclerotic heart disease, acute myocardial infarction, and other factors. It is recommended to seek timely medical attention and receive symptomatic treatment under the guidance of a physician. Specific analysis is as follows:

1. Extreme Emotional Fluctuations

Intense emotional reactions, such as extreme fear, anger, or excitement, may release large amounts of stress hormones, potentially triggering cardiac arrest. It is important to learn how to manage emotions, avoid extreme emotional swings, and thereby reduce the risk of cardiac arrest.

2. Unhealthy Lifestyle Habits

Habits such as excessive alcohol consumption, chronic sleep deprivation, and lack of physical activity can gradually damage heart health, leading to declining cardiac function and an inability to cope with sudden stress, greatly increasing the risk of cardiac arrest. Quitting smoking and alcohol, and maintaining a healthy lifestyle are strongly advised.

3. Excessive Exercise

Excessive physical exertion can sharply increase myocardial oxygen demand. When this exceeds the heart's ability to supply blood, myocardial ischemia or even cardiac arrest may occur. Before engaging in high-intensity exercise, adequate warm-up and adaptive training should be performed.

4. Coronary Atherosclerotic Heart Disease

Coronary atherosclerotic heart disease is associated with factors such as smoking and obesity. Atherosclerosis causes narrowing or blockage of the coronary arteries, which may lead to myocardial ischemia and hypoxia. In severe cases, myocardial infarction can occur, potentially resulting in cardiac arrest, often accompanied by symptoms such as chest pain and chest tightness. Under medical supervision, patients may be prescribed medications such as enteric-coated aspirin tablets, atorvastatin calcium tablets, and metoprolol tartrate sustained-release tablets for treatment.

5. Acute Myocardial Infarction

Acute myocardial infarction may be triggered by factors such as obesity and staying up late. Sudden interruption of coronary blood flow leads to severe and prolonged myocardial ischemia and hypoxia, resulting in myocardial necrosis and potentially inducing cardiac arrest. Symptoms may include intense chest pain and a sense of impending doom. Patients are advised to follow medical instructions and use medications such as heparin sodium injection, lidocaine hydrochloride injection, and dopamine hydrochloride injection to alleviate symptoms.

In daily life, it is important to maintain a healthy lifestyle, avoid overexertion and emotional fluctuations, engage in regular physical activity, and adhere to sound dietary habits.

Will my voice return to normal after a cold causes hoarseness?
In general, whether hoarseness caused by a cold can recover depends on the specific situation. Hoarseness due to mild mucosal congestion usually resolves completely; however, if the vocal cords suffer severe damage or pathological changes, recovery becomes more difficult. Daily care should include adequate vocal rest, avoiding loud talking or singing. Drinking plenty of warm water helps keep the throat moist, while spicy or excessively hot foods should be avoided to prevent irritation.

In general, cefuroxime axetil tablets cannot directly relieve cough or expel phlegm; they are only effective for treating respiratory inflammation caused by bacterial infections. To alleviate cough and sputum in daily life, measures such as drinking plenty of warm water, eating a light diet, and maintaining indoor humidity can be helpful. If symptoms persist or are accompanied by fever, yellow sputum, or similar conditions, the underlying cause should be promptly identified and treated accordingly.

In general, Jin'gan Capsules and Caffeine-Paracetamol-Pseudoephedrine Tablets are not recommended to be taken simultaneously, as their ingredients overlap; taking them together may lead to drug overdose and pose health risks. After developing a cold, choose a single symptomatic treatment medication based on your specific symptoms. Drink plenty of warm water and ensure adequate rest during medication. If symptoms persist or worsen, seek medical attention promptly to determine the underlying cause and adjust the treatment plan under medical guidance.

Can mild pulmonary hypertension be cured?
In general, whether mild pulmonary hypertension can be cured depends on whether the underlying cause is clear and removable. Cases secondary to left heart disease or lung diseases often improve once the underlying cause is addressed; however, idiopathic pulmonary hypertension is difficult to cure completely and requires long-term management. Patients with mild pulmonary hypertension should avoid smoking and excessive alcohol consumption, refrain from strenuous exercise and high-altitude environments, and reduce stress on the lungs in daily life.
