Mild hypertension is very common, 50% of hypertensives being with their diastolic BP between 90 and 104 mmHg. Many large studies, especially HDFP, had shown not only the deleterious cardiovascular effects of mild hypertension but also the benefits obtained with the therapy. The non-pharmacological approach should be the first step in the treatment of mild hypertension. Isolated systolic hypertension have a high prevalence in the elderly, increasing the cardiovascular morbidity and mortality. Sodium restriction and, if necessary, vasodilators increasing the arterial compliance seem to be the logical approach to treat isolated systolic hypertension. Finally, eclampsia is the most serious complication of pregnancy - induced hypertension. The treatment with bed rest and either betablockers or methyldopa is beneficial. If eclampsia occurs hydralazine, magnesium sulphate or nifedipine should be used.
