The correlation for diastolic and systolic blood pressure was studied in two samples of quartets each consisting of two pairs. The first sample comprised pairs of sisters and their husbands, and the second sample was comprised of brothers and their wives. All siblings were between 30 and 55 years of age and had been married for at least 5 years. It was found that unrelated men married to sisters had a significant correlation in both diastolic (r = 0.28) and systolic (r = 0.41) pressure. For systolic blood pressure, the correlation between pairs of unrelated men married to sisters was significantly larger than the homologous correlation existing in pairs of brothers married to unrelated women. The correlations of systolic and diastolic pressure in sisters were significantly smaller than the same correlations measured in the wives of brothers. The correlations in height for men, used as an internal control to compare marital and genetic effects, were unaffected by marriage, as expected. The correlations in height for pairs of sisters, however, were no larger than those observed in pairs of unrelated women married to brothers. It was concluded that in adult married men and women of the Ferrara population, aged 30 to 55 years, the influence of genetic factors on blood pressure is less important than the influence of cultural factors.

The antihypertensive and anti-ischaemic effects of methyldopa and captopril were compared in 12 hypertensive patients with coronary artery disease. The antihypertensive effect of alpha-methyldopa (A) and captopril (C) were significant and similar. On the other hand, while methyldopa did not increase the product of systolic pressure and heart rate and did decrease the effort-induced S-T segment depression, C increased the double product (DP) and decreased the ischaemic S-T changes. Captopril might be useful in the treatment of hypertensive patients with coronary artery disease.

A patient who experienced partial complex seizures while receiving therapeutic doses of trazodone is described. Only one previous report in the literature involved seizures (grand mal) associated with the administration of trazodone.

After describing the phenomenon of sudden death both from a historical and literary viewpoint, the paper tackles the problem of its definition which is not yet univocal in the present literature, and identifies it mainly in its chronology.

Twelve normotensive patients with coronary artery disease and stable effort-induced angina pectoris were selected: the antiischemic effect of captopril was studied. A maximal cycloergometer effort test was obtained before (base) and after administration of placebo or captopril (50 mg p.o.). The following parameters were measured: heart rate (HR), blood pressure (BP), maximal rate/pressure product (MRPP), maximal workload sustained, (MWS), maximal working time (MWT), and S-T depression at MRPP. The base and placebo were similar. Compared to them captopril augmented the MWT, increased the MWS, reduced S-T depression at MRPP, and decreased the number of patients with effort-induced angina pectoris. The antiischemic effect of captopril seems related both to its effect on HR and BP, and to a local enhancement of coronary blood flow.
