INTRODUCTION: The etiology of essential hypertension is multifactorial. Therefore, treatment with combinations of antihypertensive agents acting on multiple targets is necessary for successful therapy in the majority of patients. According to the experience and clinical data accumulated so far, combination therapy with three agents from different pharmacological classes is required in approx. 30% of patients in order to achieve long-term blood pressure control. The primary objective of the PETRA study was to evaluate the efficacy of blood pressure (BP) control with once daily administration of the different dosage strengths of the once-daily, triple fixed combination of perindopril, indapamide, and amlodipine...

Some human diseases, including obesity, Type II diabetes, and numerous cancers, are thought to be influenced by environments experienced in early life, including in utero. Maternal diet during the perinatal period may be especially important for adult offspring energy balance, potentially affecting both body composition and physical activity. This effect may be mediated by the genetic background of individuals, including, for example, potential "protective" mechanisms for individuals with inherently high levels of physical activity or high basal metabolic rates...
