    Abstract:
    BACKGROUND: Heart failure is a frequent pathology that requires a high degree of hospitalization. These characteristics have a high assistance cost. The purpose of this study was to evaluate the prevalence, acuteness, predisposing factors and therapy carried out in patients of a northeastern Italian town, and to evaluate their impact on health costs. METHODS: We have examined patient under observation of the Department of Emergency at the Padua Hospital for 12 months. They had been hospitalized for heart failure symptoms. They all underwent individual and pharmacological anamnesis, objective exam, ECG, thorax X-rays and echocardiogram. The health expenses were calculated in relation to hospital stay, the cost of daily assistance, exams and medical treatments used. RESULTS: 630 patients of both sexes (422 males and 208 females) aged 74.6 +/- 6.1 were studied. Among significantly interrelated factors were: hypertension in 51.4% of the patients; diabetes mellitus in 9% of the patients; hypercholesterolemia in 31.3% of the patients; hypertriglyceridemia in 7.2% of the patients; cigarettes smoking in 19.3% of the patients, whereas obesity was present in 19.7% of all the subjects. Heart diseases directly correlated with heart failure were respectively: myocardial ischemia (65.6%); hypertensive cardiopathy (14.7%); idiopathic dilatative (15%); and valvular cardiopathy (4.7%). In 9.5% of cases, patients presented episodes of TIA, ictus, or they were carriers of neurologic focal deficiencies. As far as NYHA functional class was concerned, the third was most prevalent with a different distribution (p < 0.05) between males and females. ACE inhibitors, digitalis and calcium antagonists are to be indicated among the most widely used drugs. The health cost for patients in this survey was deduced on the basis of: average; hospitalization stay (9.8 days); estimated daily expenses for patient and for further controls (L. 282,000); the area of users (85% of residents). Therefore the full hospital assistance of patients with heart failure is approximately L. 2.1 thousand millions. CONCLUSIONS: Given the high preponderance of heart failure, the frequent relation with vascular risk factors and with ischemic cardiopathy, further investigation is necessary to curb these high rates. On the other hand, the NYHA advanced state of patients is not likely to allow lower costs in relation to hospital admission or the reduction of hospital stay. Nevertheless, the individualization of standardized therapeutic protocols and an adequate home care surveillance follow-up may reduce the number of hospitalizations and consequently the connected health expenses.
