[The characteristics of those who have died with primary or recurrent myocardial infarct].

In 93 decreased patients, 31 with first myocardial infarction and 62 with repeated myocardial infarction, the following indices were studied: risk factors, previous history, clinical onset, complications, ECG localization, time and cause of death, pathologicoanatomical changes. There was a tendency toward a greater frequency of cardiogenic shock in the patients who died during their first infarction. In the patients who died during a repeated infarction the following events were significantly more frequent: pulmonary thromboembolism (9.

[The characteristics of repeated myocardial infarcts in men and women].

117 patients, 89 men and 28 women, with repeated myocardial infarction were followed up for a two year period. The following were taken into consideration: risk factors, number and localization of previous infarctions, interinfarction period, clinical onset of the new infarction, complications, electrocardiographic changes, time of death, causes of death, pathologicoanatomical localization of the new and old infarctions in comparison with the electrocardiographic localization. Statistically significant differences between the two sexes were found for the death of cardiogenic shock--48.

[Hypokalemia caused by nifedipine].

A case of 72 year old woman with arterial hypertension is presented. The woman was treated with clonidine and nifedipine. Hypokalemia was found by normal urine excretion of potassium and normal intraerythrocyte potassium contents.

[Clinico-pharmacologic study on the liquid form of nifedipine in treating hypertensive crisis].

33 patients with hypertensive crisis were treated with a 2% Nifedipine solution for oral use. 5 patients had taken 5 mg, 16 patients--10 mg and 12 patients--20 mg of the drug. The antihypertensive action was followed up to the 6-th hour.
