Long-Term Prognostic Impact of Sex in Patients with Chronic Coronary Syndrome: A 17-Year Prospective Cohort Study.

Background: Women and men with chronic coronary syndrome (CCS) have different clinical features and management, and studies on mid-term prognosis have reported conflicting results. Our objective was to investigate the impact of the female sex in the prognosis of the disease in the very long term. Methods and Results: We investigated differential features and very long-term prognosis in 1268 consecutive outpatients with CCS (337 [27%] women and 931 [73%] men). Women were older than men, more likely to have hypertension, diabetes, angina, and atrial fibrillation, and less likely to be exsmoker/active smoker and to have been treated with coronary revascularization (p < 0.05 for all). The prescription of statins, antiplatelets, and betablockers was similar in both groups. After up to 17 years of follow-up (median = 11 years, interquartile range = 4-15 years), cumulative incidences of acute myocardial infarction (10.2% vs. 11.8%) or stroke (11% vs. 10%) at median follow-up were similar, but the risks of major cardiovascular events (acute myocardial infarction, stroke, or cardiovascular death, 41.2% vs. 33.6%), hospital admission for heart failure (20.9% vs. 11.9%), or cardiovascular death (32.3% vs. 22.1%) were significantly higher for women (p < 0.0005), with a nonsignificant trend to higher overall mortality (45.2% vs. 39.1%, p = 0.07). However, after multivariate adjustment, all these differences disappeared. Conclusion: Although women and men with CCS presented a different clinical profile, and crude rates of major cardiovascular events, heart failure and cardiovascular death were higher in women, female sex was not an independent prognostic factor in this study with up to 17 years of follow-up.

Nutritional Intervention in Malnourished Hospitalized Patients with Heart Failure.

BACKGROUND AND AIMS: Hospitalized patients with heart failure who are malnourished present a worse prognosis than those with an adequate nutritional status. We undertook this study to assess whether a nutritional intervention in malnourished hospitalized patients with heart failure benefits morbidity and mortality. METHODS: A multicenter, randomized, controlled clinical trial was conducted. A total of 120 malnourished hospitalized patients due to acute heart failure were randomised to conventional heart failure treatment or conventional heart failure treatment combined with an individualized nutritional intervention. The primary endpoint of this study was a composite of all-cause death or readmission for worsening of HF, with a maximum follow-up of 12 months. Analysis was by intention to treat. RESULTS: Recruitment was stopped early according to the study protocol after completing the follow-up of the first 120 patients enrolled (59 in the intervention group and 61 in the control group). Both groups were homogeneous in baseline characteristics. At 12 months, the primary outcome occurred in 27.1% of patients in the intervention group and in 60.7% of patients in the control group (hazard ratio 0.45; 95% confidence interval [CI], 0.19-0.62, p = 0.0004). In total, 20.3% of patients died in the intervention group and 47.5% in the control group (hazard ratio 0.37, 95% CI, 0.19-0.72, p = 0.003). Readmission due to heart failure was also lower in the intervention group (10.2 vs. 36.1%, p = 0.001). CONCLUSION: Nutritional intervention in malnourished hospitalized patients with heart failure reduces the risk of death from any cause and the risk of readmission for worsening of heart failure (ClinicalTrial.govNCT01472237).

Rationale and design of PICNIC study: nutritional intervention program in hospitalized patients with heart failure who are malnourished.

INTRODUCTION AND OBJECTIVES: Hospitalized patients with heart failure who are malnourished present a worse prognosis than those with an adequate nutritional status. It is unknown whether a nutritional intervention can modify the prognosis of these patients. The aim of this study is to assess the efficacy of a nutritional intervention on morbidity and mortality in hospitalized patients with heart failure who are malnourished. METHODS: PICNIC is a multicentre, randomized, controlled trial in which hospitalized patients with heart failure and malnutrition, as defined by the Mini Nutritional Assessment, are randomly assigned to conventional management of heart failure or conventional management of heart failure and an individualized nutritional intervention consisting of 3 points: optimization of diet, specific recommendations, and prescription, if deemed necessary, of nutritional supplements. A sample size of 182 patients for a maximum follow-up of 12 months has been estimated. The primary endpoint is time to death from any cause or rehospitalization because of heart failure. Analysis is by intention to treat. CONCLUSIONS: PICNIC study will determine the prognostic impact of a nutritional intervention in hospitalized patients with heart failure who are malnourished.

[Impact of malnutrition on long-term mortality in hospitalized patients with heart failure]. / Influencia de la desnutrición en la mortalidad a largo plazo de pacientes hospitalizados por insuficiencia cardiaca.

INTRODUCTION AND OBJECTIVES: The prevalence of malnutrition among patients with heart failure and the role it might play in prognosis is not currently known. The aim of this study was to analyse the prevalence and risk of malnutrition as well as its possible influence on long-term mortality in patients with heart failure. METHODS: A prospective analysis was conducted on 208 patients discharged consecutively from our centre between January 2007 and March 2008 after being hospitalised with heart failure. Before discharge, a complete nutritional assessment was performed and diagnosis of malnutrition and risk of malnutrition was done with the Mini Nutritional Assessment. Its possible independent association with mortality was assessed by a Cox multivariate analysis. RESULTS: The mean age of the patients was 73 ± 10 years, with 46% women; the most common aetiology of heart failure was ischaemia (41%). In addition, 13% were classified as malnourished, 59.5% at risk of malnutrition and 27.5% were well-nourished. At a median follow-up of 25 months, mortality in the three groups was 76%, 35.9% and 18.9%, respectively (log-rank, P<.001). In the Cox multivariate analysis, the malnutrition state was an independent predictor of mortality (hazard ratio 3.75, 95% confidence interval, 1.75-8.02, P=.001). CONCLUSIONS: Malnutrition and the risk of malnutrition are highly prevalent in patients hospitalised for heart failure. Furthermore, we found that the state of malnutrition as defined by the Mini Nutritional Assessment survey is an independent predictor of mortality in these patients.

[Should Angiotensin-converting enzyme inhibitors be continued over the long term in patients whose left ventricular ejection fraction normalizes after an episode of acute myocarditis?]. / Se deben mantener los inhibidores de la enzima de conversión de la angiotensina a largo plazo en pacientes que normalizan la fracción de eyección tras un episodio de miocarditis aguda?

It is well established that long-term administration of angiotensin-converting enzyme (ACE) inhibitors has a favorable effect in patients with chronic heart failure and dilated cardiomyopathy. However, less information is available on patients whose left ventricular ejection fraction normalizes after an episode of systolic dysfunction secondary to acute myocarditis. We followed 35 patients who were diagnosed at our center between 1987 and 1995 with acute myocarditis and an ejection fraction<45%. All were taking ACE inhibitors. After 34 (23) months of follow-up, the left ventricular ejection fraction was >50% in all 35 patients. Treatment with ACE inhibitors was discontinued in 15 of the 35 patients, while the other 20 continued ACE inhibitor therapy. After 3 years of follow-up, no death had occurred, but the incidence of new episodes of heart failure with a left ventricular ejection fraction<45% was higher in patients who stopped taking ACE inhibitors (33% vs 5%, P=.064), and their ejection fraction was lower (47 [12%] vs 57 [11%], P=.002). These results suggest that ACE inhibitors should be continued over the long term in these patients.

[Oral anticoagulation for nonvalvular atrial fibrillation: are scientific recommendations effective and safe in daily clinical practice?]. / Anticoagulación oral en la fibrilación auricular no valvular: 'son efectivas y seguras las recomendaciones científicas en la práctica clínica diaria?

INTRODUCTION AND OBJECTIVES: To study the efficacy and safety of an oral anticoagulation protocol for the treatment of nonvalvular atrial fibrillation, based on scientific associations' recommendations, in unselected patients seen in daily clinical practice. METHODS: The study included all consecutive patients with permanent nonvalvular atrial fibrillation who attended two outpatient cardiology clinics between February 1, 2000 and February 1, 2002. They were treated according to an anticoagulation protocol based on Spanish Society of Cardiology and American College of Cardiology/American Heart Association/European Society of Cardiology guidelines. Patients were followed up prospectively for major events, such as death, stroke, transient ischemic attack, peripheral embolism and severe hemorrhage, which were recorded by treatment group. RESULTS: A total of 624 patients were included in the study. Those receiving anticoagulation therapy (n=425; 68%) more frequently had hypertension, diabetes and previous embolism as well as a greater number of cardioembolic risk factors (P< .001). Overall, 93% of non-anticoagulated patients received platelet aggregation inhibitors (92% received aspirin). After a median follow-up of 21 months, the probability of an embolic event was lower in anticoagulated patients (0.81% vs 14.04%; P< .001), as was all-cause mortality (3.27% vs 6.42%; P=.003). However, there was no significant difference in the probability of severe bleeding (2.75% vs 2.93%; P=.96). Results were unchanged after adjustment for age, sex, and previous embolic events. CONCLUSIONS: Oral anticoagulation therapy for nonvalvular atrial fibrillation implemented according to scientific associations' recommendations is effective and safe in daily clinical practice.

[Short- and long-term prognosis of infective endocarditis in non-injection drug users: improved results over 15 years (1987-2001)]. / Pronóstico a corto y largo plazo de la endocarditis infecciosa en pacientes no usuarios de drogas por vía parenteral. Resultados durante un período de 15 años (1987-2001).

INTRODUCTION AND OBJECTIVES: The treatment of infective endocarditis has undergone significant change within the last few years. The aim of this study was to evaluate the clinical features and prognosis of infective endocarditis over both the short and long term in patients who are not intravenous drug users. PATIENTS AND METHOD: We carried out a prospective study of 222 consecutive patients who were diagnosed with infective endocarditis between 1987 and June 2001 at two centers. RESULTS: Their mean age was 48 (19) years, with 145 (65%) being male. Overall, 154 (69%) had native valve endocarditis and 68 (31%) had prosthetic valve endocarditis. In 61 patients (27%), no predisposing heart disease was found. Staphylococci were the causal microorganisms in 37% of cases (81 patients), and streptococci, in 35% (78 patients). Some 48% of patients underwent surgery during the active disease phase. Overall, inpatient mortality was 17% (39 cases); a significant decrease had occurred in recent years, from 25% in 1989-1995 to 12% in 1996-2001 (P<.01). In addition, the percentage undergoing early elective surgery had increased between the two periods, from 22% to 32% (P<.05). During a follow-up of 60 (48) months, 15 patients (8%) needed late cardiac surgery and 18 (10% of the whole series) died. The 6-year survival rate was 72% overall, and 80% in those who survived the active disease phase. CONCLUSIONS: Short- and long-term prognoses for patients with infective endocarditis appear to have improved over recent years at our hospitals.
