[Effects of patient information, compliance and medical control on prognosis in chronic heart failure].
The impact of treatment on prognosis of patients with chronic congestive heart failure depends not only on pharmacological therapy but also on nonpharmacological aspects of patient management. Patient compliance, life style changes, salt and fluid restriction, detailed patient information and measures of self control greatly affect therapeutic efficacy. Reasons for hospitalizations and emergency room visits: In an analysis of 82 admissions of patients for decompensated chronic congestive heart failure we found poor compliance with drug treatments or dietary instructions as causally related factors in 30 patients, uncontrolled hypertension in 22 patients, acute infection in 18 and acute myocardial ischemia in 18 patients. More than half of the patients had weight gain before decompensation, that had not been adequately answered by changes in medication. Inadequate patient information: Inadequate knowledge about necessary life style changes at the time of hospital discharge is often found in patients with chronic heart failure. Less than 50% of these patients remembered correctly the instructions on key issues of necessary life style changes and diet. Drug treatment of heart failure: Recent controlled drug trials have not gained enough weight in therapeutic decisions of physicians treating heart failure patients. While ACE-inhibitors have been shown to improve longevity in congestive heart failure only 6% of patients with heart failure are treated with these drugs, while 5% are treated with calcium antagonists which have not been proven to be of symptomatic or prognostic benefit and may be harmful as well in this disease. Inadequate dosage in patients with chronic renal failure or in elderly patients as well as inadequate choice of drugs lead to side effects in a considerable percentage of patients.
