Summary
The prevalence of primary and secondary hypertension and of heart and kidney involvement was thoroughly studied in 689 hypertensive subjects derived from a blood pressure screening examination of a total population sample of Swedish men (n=7,452).
The prevalence of secondary hypertension was found to be only 5%, the prevalence of surgically curable hypertension being even lower. Left ventricular hypertrophy and slight heart enlargement were each found in about one-third of the hypertensive patients, while severe heart enlargement, left ventricular hypertrophy on ECG, proteinuria, abnormal serum creatinine and urinary sediment were each found in about 5%.
On the basis of these findings, a minimum pre-treatment workup in uncomplicated hypertension is proposed.
