Background: Despite improved management of heart failure patients, their prognosis remains poor.
Objectives: To characterize hospitalized HF patients and to identify factors that may affect their short and long-term outcome in a national prospective survey.
Methods: We recorded stages B-D according to the American College of Cardiology/American Heart Association definition of HF patients hospitalized in internal medicine and cardiology departments in all 25 public hospitals in Israel.
Results: During March-April 2003, 4102 consecutive patients were recorded. Their mean age was 73 ± 12 years and 57% were males; 75.3% were hypertensive, 50% diabetic and 59% dyslipidemic; 82% had coronary artery disease, 33% atrial fibrillation, 41% renal failure (creatinine ³ 1.5 mg/dl), and 49% anemia (hemoglobin £ 12 g/dl). Mortality rates were 4.7% in-hospital, 7.6% at 30 days, 18.7% at 6 months and 28.1% at 12 months. Multiple logistic regression analysis revealed that increased 1 year mortality rate was associated with New York Heart Association III–IV (odds ratio 2.07, 95% confidence interval 1.78–2.41), age (for 10 year increment) (OR 1.41, 95% CI 1.31–1.52), renal failure (1.79, 1.53–2.09), anemia (1.50, 1.29–1.75), stroke (1.50, 1.21–1.85), chronic obstructive pulmonary disease (1.25, 1.04–1.50) and atrial fibrillation (1.20, 1.02–1.40).

Background: Heart failure with preserved systolic left ventricular function is a major cause of cardiac disability.
Objectives: To examine the prevalence, characteristics and late clinical outcome of patients hospitalized with HF-PSF on a nationwide basis in Israel.
Methods: The Israel nationwide HF survey examined prospectively 4102 consecutive HF patients admitted to 93 internal medicine and 24 cardiology departments in all 25 public hospitals in the country. Echocardiographic LV function measurements were available in 2845 patients (69%). The present report relates to the 1364 patients who had HF-PSF (LV ejection fraction ≥ 40%).
Results: Mortality of HF-PSF patients was high (in-hospital 3.5%, 6 months 14.2%, 12 months 22.0%), but lower than in patients with reduced systolic function (all P < 0.01). Mortality was higher in patients with HF as the primary hospitalization diagnosis (16.0% vs. 12.5% at 6 months, P = 0.07 and 26.2% vs. 18.0% at 12 months, P = 0.0002). Patients with HF-PSF who died were older (78 ± 10 vs. 71 ± 12 years, P < 0.001), more often female (P = 0.05) and had atrial fibrillation more frequently (44% vs. 33%, P < 0.01). There was also a relationship between mortality and pharmacotherapy: after adjustment for age and co-morbid conditions, mortality was lower in patients treated with angiotensin-converting enzyme inhibitors (P = 0.0003) and angiotensin receptor blockers (P = 0.002) and higher in those receiving digoxin (P = 0.003) and diuretic therapy (P = 0.009).
Conclusions: This nationwide survey highlights the very high late mortality rates in patients hospitalized for HF without a decrease in systolic function. The findings mandate a focus on better evidence-based treatment strategies to improve outcome in HF-PSF patients.

Background: Left ventricular outflow gradient is associated with increased morbidity and mortality in hypertrophic cardiomyopathy. Alcohol septal ablation is the alternative to surgery in cases refractory to drug therapy. The implication of LVOG measured 1 week post-ASA for prediction of outcome is unknown.
Objective: To observe the pattern of LVOG course and prediction of long-term clinical and hemodynamic outcome of ASA.
Methods: Baseline clinical and echocardiographic parameters were prospectively recorded in 14 consecutive patients with a first ASA, at the time of ASA, 3 and 7 days after ASA (in-hospital) and 3 and ≥ 12 months after ASA (last follow-up).
Results: There was improvement in NYHA class, exercise parameters and LVOG in 11 of 14 patients (P < 0.005 in all). Maximal creatine kinase level was lower than 500 U/L in those without such improvement and 850 U/L or higher in successful cases. LVOG dropped from 79 ± 30 to 19 ± 6 mmHg after the ASA. LVOG was 50 ± 21 mmHg on day 3, 39 ± 26 on day 7, 32 ± 26 at 3 months and 24 ± 20 mmHg at last follow-up. LVOG identified 27% sustained procedural successes on day 3 and 73% on day 7. The overall predictive accuracy of the test for sustained success and failure was 36% on day 3 and 71% on day 7. Combination of maximal CK and LVOG on day 7 showed four distinct outcome patterns: "early success" with low LVOG and high CK (73% of successful cases), "late success" with high LVOG and high CK, and "early failure" and "late failure" with both low CK and high or low LVOG, respectively
Conclusion: LVOG measurement 7 days post-ASA combined with maximal CK levels predicts late procedural outcome in the majority of patients

Background: Previous studies found some factors such as physical exertion, anger and heavy meals to be triggers for acute coronary syndrome.
Objectives: To estimate the relative risk of an ACS episode associated with positive and negative emotional experiences and anger as potential work-related triggers.
Methods: A total of 209 consecutive patients were interviewed a median of 2 days after a cardiac event that occurred at work or up to 2 hours later. The case-crossover design was used. Positive and negative emotional experiences and anger episodes in the hours immediately before the onset of ACS were compared with episodes in the comparable hours during the previous workday. For anger the episodes were compared with the usual frequency at work during the previous year. Positive and negative emotional experiences were assessed by the PANAS questionnaire (Positive and Negative Affect Scale), and anger by the Onset Anger Scale.
Results: The relative risks of an acute coronary event during the first hour after exposure to negative and positive emotional experiences were RR = 14.0 (95% confidence interval 1.8–106.5) and RR = 3.50 (95% CI, 0.7–16.8) respectively and RR = 9.0 (95% CI, 1.1–71) for an episode of anger. Using conditional logistic regression analysis, the highest relative risk was associated with negative emotional experiences.
