[Clinical characteristics, treatment and short-term morbidity and mortality of patients with heart failure followed in heart failure clinics. Results of the BADAPIC Registry].
ABSTRACT Despite recent improvements in therapy, heart failure is still associated with high mortality and hospitalization rates. New management strategies such as heart failure clinics could help to improve this situation.
We analyzed the clinical features, treatment, morbidity and mortality of 3909 patients with heart failure followed at 62 heart failure clinics in Spain in the last 3 years (BADAPIC Registry). Mean follow-up time was 13 +/- 4 months.
Mean age was 66 +/- 12 years (40% of the patients were older than 70 years), and 67% were male. Etiology was ischemic heart disease in 41% of the cases, systemic hypertension in 19%, idiopathic dilated cardiomyopathy in 17%, valvular disease in 17% and other in the remaining 6%. Left ventricular ejection fraction was < 45% in 68% of the patients. After inclusion in the BADAPIC Registry, 86% of the patients received diuretics, 37% received digoxin, 87% were given angiotensin-converting enzyme inhibitors or angiotensin receptor antagonists, 32% received spironolactone, 59% received beta blockers and 28% were given nitrates. Actuarial survival at 24 months was 87%, admission-free survival was 80% and event-free survival was 76%. Survival was similar in men and women, higher in patients younger than 70 years (P<.05), and slightly higher in those with left ventricular ejection fraction > 45% (P=.08).
The treatment received by patients included in the BADAPIC Registry closely approached the recommended standards. Their short-term survival rate was very high.

ABSTRACT: Heart failure is a major health care problem in Spain, although its precise impact is unknown due to the lack of data from appropriately designed studies. In contrast with the 2% prevalence of heart failure elsewhere in Europe and in the United States, studies in Spain report figures of 5%, probably because of methodological limitations. Heart failure consumes enormous quantities of health care resources; it is the first cause of hospitalization in persons aged 65 years or older and represents 3% of all hospital admissions and 2.5% of health care costs. There are two patterns of heart failure: one with preserved systolic function, more often associated with high blood pressure, and another with depressed systolic function, more often associated with ischemic heart disease. In 2010, heart failure accounted for 3% of all deaths in men and for 10% of all deaths in women. In recent years, the mortality rate from heart failure has gradually fallen. The rise in hospital admissions for heart failure and the decrease in mortality from this cause could partly be explained by temporary changes in diagnostic coding, but there is evidence that the reduced mortality could also be due to adherence to clinical practice guidelines.

ABSTRACT: Heart failure (HF) is a serious health problem in Spain because it has a high mortality rate and causes considerable costs to the health-care system. This paper presents a study made in the Spanish province of Ourense to study the survival of patients with HF related to the ventricular function or other possible risk factors (RF) associated with the HF prognosis. A prospective cohort study was performed, considering any patient hospitalized due to HF from 1 January 1999 to 31 December 2002 (5318 patients) who had undergone an echocardiography that showed systolic or diastolic dysfunction as potential participants (2387 patients). After at least 24 months of the index episode of hospitalization, a sample of 2384 patients was chosen by random sampling. The principal measurement was based on survival and the differences observed in the performance of the left ventricular ejection fraction, of functional class (FC) of HF and of other clinical and epidemiological characteristics. The Kaplan-Meier, log-rank and Cox tests were used. Mean age of the patients 74.84 (range 36-95); 53.4% males and 56.5% first admission. The most common antecedent was arterial hypertension (HTA) (59.9%), followed by valvulopathy (41.9%) and heart disease (HD) (26.8%). A total of 44.3% of the patients had atrial fibrillation-flutter (AF). Global survival at 5 years was 47.9% and specific survival rate for HF was 74.8%. There were no significant differences in survival between patients with heart failure and preserved systolic function (HF-PSF) and those who suffered systolic dysfunction (p=0.248). Prognostic factors of mortality in patients with HF are: advanced functional class (class III-IV) prior to admission (Hazard ratio [HR] 5.37), deterioration of the glomerular filtration rate (GFR) (HR 0.98), hypoalbuminemia (HR 0.59), hyponatremia (HR 0.93) and hyperkalemia (HR 1.79). The Castelli index higher than 4.5 is in the limit of statistical significance. Global survival rate observed at 5 years of research is similar to the results found in already-published papers. Specific survival rate for HF is lower and there are no differences in the survival rate with regard to the left ventricle ejection fraction (E(f)). However, we show that hypoalbuminemia, hyperkalemia and high Castelli index are important prognostic factors of mortality in patients with HF.Revista Clínica Española 10/2010; 210(9):438-47. · 2.01 Impact Factor

ABSTRACT: INTRODUCTION AND OBJECTIVES: Scarce research has been performed in ambulatory patients with chronic heart failure in the Mediterranean area. Our aim was to describe survival trends in our target population and the impact of prognostic factors. METHODS: We carried out a population-based retrospective cohort study in Catalonia (north-east Spain) of 5659 ambulatory patients (60% women; mean age 77  years) with incident chronic heart failure. Eligible patients were selected from the electronic patient records of primary care practices from 2005 and were followed-up until 2007. RESULTS: During the follow-up period deaths occurred in 950 patients (16.8%). Survival after the onset of chronic heart failure at 1, 2, and 3 years was 90%, 80%, 69%, respectively. No significant differences in survival were found between men and women (P=.13). Cox proportional hazard modelling confirmed an increased risk of death with older age (hazard ratio=1.06; 95% confidence interval, 1.06-1.07), diabetes mellitus (hazard ratio=1.53; 95% confidence interval, 1.33-1.76), chronic kidney disease (hazard ratio=1.73; 95% confidence interval, 1.45-2.05), and ischemic heart disease (hazard ratio=1.18; 95% confidence interval, 1.02-1.36). Hypertension (hazard ratio=0,73; 95% confidence interval, 0,64-0,84) had a protective effect. CONCLUSIONS: Service planning and prevention programs should take into consideration the relatively high survival rates found in our area and the effect of prognostic factors that can help to identify high risk patients.
