Systolic heart failureSymptoms of systolic heart failureCauses of systolic heart failureTreatment of systolic heart failure The first goal of treatment for HFrEF is to treat any underlying causes. For example, if you have hypertension, you may need drugs to manage your blood pressure. If you have diabetes, you should take medications to control blood sugar. Some patients may need surgery or an implanted device to help the heart function.
Your healthcare provider may also recommend some lifestyle changes to help manage underlying conditions and keep your heart as healthy as possible:
Avoid alcohol, smoking and illegal drugs.
Exercise regularly. Start slowly, and always warm-up and cool down.
Limit salt intake. Most patients with heart failure should consume no more than 1,500 mg of sodium per day.
Maintain a healthy weight. Track your weight, and report any sudden increases to your healthcare provider.
Participate in a cardiac rehab program.
