Systolic blood pressure and (cardiac) mortality over 15 years after venous coronary bypass surgery.
The aim of the present study was to determine the influence of pre-operative systolic blood pressure and systolic blood pressure 1 and 5 years after venous coronary bypass surgery on subsequent cardiac and non-cardiac mortality. ⋯ These findings underline the importance of systolic blood pressure control in the initial years after coronary bypass surgery.

Heart rate dependency of premature ventricular contractions. Correlation between electrocardiographic monitoring and exercise-related patterns.
The identification of the response of ventricular arrhythmias to exercise testing could provide important information in the clinical setting but is difficult to obtain as no definite criteria are available. The aim of this study was to evaluate whether analysis of spontaneous heart rate dependency of premature ventricular contractions evaluated by means of 24 h electrocardiographic monitoring is capable of predicting their behaviour during exercise. ⋯ Identification of spontaneous behaviour between the incidence of premature ventricular contractions and the length of the preceding cardiac cycle may predict the behaviour of arrhythmias during exercise.
