What should I do if I have a fever due to heart disease?

Heart disease is a very common condition. In recent years, its incidence has been rising steadily, significantly affecting people’s health and daily life. So, what should be done if a patient with heart disease develops a fever?

What to Do When a Patient with Heart Disease Develops a Fever

If a patient with heart disease develops a fever, prompt symptomatic treatment is essential. If the fever results from a common cold, antiviral medications and antibiotics may be used. When body temperature exceeds 38.5°C, ibuprofen can be administered for antipyretic effect. For temperatures at or below 38.5°C, physical cooling methods—such as tepid sponging—are recommended and pose no risk to health. Patients with heart disease must prioritize rest during febrile episodes, especially those with myocarditis. Physical activity should be strictly avoided. Increased fluid intake is encouraged to promote viral clearance and metabolism. In severe cases, intravenous (IV) hydration therapy may be necessary. During colder seasons, patients should consume a low-salt, low-fat, light, and easily digestible diet.

Fever increases cardiac workload in patients with heart disease, potentially worsening myocardial ischemia and causing cardiac discomfort. Under a physician’s guidance, nitrates, beta-blockers, and antiplatelet agents—such as isosorbide mononitrate tablets, metoprolol tartrate extended-release tablets, and enteric-coated aspirin tablets—may be prescribed to enhance myocardial blood supply, slow heart rate, and alleviate symptoms. Strict adherence to prescribed medication regimens is critical; self-medication without medical supervision is strongly discouraged.

Patients are advised to maintain a light, balanced diet, avoid spicy or irritating foods, abstain from tobacco and alcohol, follow regular sleep schedules, and avoid staying up late. We hope this information proves helpful.
