The distribution of SCD, with short (< or =1h) and longer (1-24 h) time of death, on days of lowest (Io) GMA differs from that on days of unsettled, active, or stormy (IIo-IVo) GMA. Despite the general trend to higher SCD frequency at IIo-IVo GMA, certain rapidly dying groups (< 65 y males, > 65 y females) showed a strong trend toward higher numbers of SCD at the lowest GMA.

In recent years, the possible association of changes in mortality from cardiovascular disease and myocardial infarction (MI) and deaths related to violence and the suicide rate has been repeatedly discussed. This study examined the relationship between cosmic physical changes (solar, geomagnetic and other space activity parameters) and changes in the total number of in-hospital and MI-related deaths and deaths from suicide to determine if a relationship exists between the distribution of total and MI-related deaths with suicide over time; some differences in the serotonergic mechanisms involved in the pathogenesis of MI and suicide were also taken into account. All suicides (n = 2359) registered in the State of Israel from 1981 to 1989 (108 months) were analysed and compared with the total number of deaths (n = 15601) and deaths from MI (n = 1573) in a large university hospital over 180 months (1974-1989). The following were the main features of the Results. (1) Monthly suicide rate was correlated with space proton flux (r = 0.42, P = 0.0001) and with geomagnetic activity (r = -0.22, P = 0.03). (2) Total hospital and MI-related deaths were correlated with solar activity parameters (r = 0.35, P < 0.001) and radiowave propagation (r = 0.52-0.44, P < 0.001), an with proton flux (r = -0.3 to -0.26, P < 0.01). (3) Monthly suicide distribution over 108 months was correlated with MI (r = -0.33, P = 0.0005) and total hospital mortality (r = -0.22, P = 0.024). (4) Gender differences were prominent.(ABSTRACT TRUNCATED AT 250 WORDS)

AimsThe burden of heart failure (HF)-related hospitalization and mortality of female patients with HF is substantial. Currently, several gender-specific distinctions have been recognized amongst HF patients, but their relationships to outcomes have not been fully elucidated. Accordingly, in the current work, we aimed to explore gender-specific clinical and echocardiographic measures and to assess their potential impact on outcome. Methods and resultsWe studied all consecutive HF patients, aged 50 or older, who had been hospitalized between January 2000 and December 2009, and had undergone at least one echocardiography study. A comparative analysis of clinical and echocardiographic findings was performed between 5228 males and 4107 females. Patients were followed for a mean of 2.8 + 2.6 years. Females compared with males had less ischaemic heart disease, prior stroke, chronic renal failure, and COPD, and higher rates of hypertension, AF, obesity, valvular abnormalities, and pulmonary hypertension. Unadjusted 30-day and 1-year mortality rates were higher among women, while age-adjusted rates were similar. Predictors of outcomes varied between genders. Female-specific predictors of mortality included aortic stenosis, pulmonary hypertension, and malignancy, whereas diastolic dysfunction and chronic renal failure were found to be male-specific predictors. ConclusionsAge-adjusted mortality rates of male and female hospitalized HF patients are similarly high. Predictors of mortality, however, are gender distinctive, and these measures may allow a better identification of high-risk HF patients.--
