[Incidence and the degree of cardiovascular changes and causes of death in 717 patient who died of chronic pyelonephritis with and without arterial hypertension].
The authors examined 9015 necropsies, over the age of 14, in a general hospital for the period January 1, 1967 to March 1, 1979. They found that the chronic pyelonephritis (ChPN) was the most frequent renal diseases with a lethal end--62.83 per cent of the renal patients and 7.95 per cent of all deceased. In 458 (63.87%) of them ChPN was accompanied by arterial hypertension (AH), which with an average duration of 8.8 years had caused a considerable hypertrophy of left ventricle. A better manifested atheromatosis of aorta, coronary, cerebral and renal arteries, being statistically significant, was found in the deceased with ChPN and AH as compared with the control group of 524 subjects, deceased without hypertension but that atheromatosis was less manifested than in those that died of hypertonic disease. That fact was explained by the authors with the shorter duration of hypertension in ChPN, with a more strict nutritional regimen among them, with the shorter life span and azotemia, as well as with the more active involvement of adrenergic systems of the patients with ChD. Whereas in 2/3 of the deceased with ChPN, without hypertension, the cause for the lethal end was uremia and urosepsis, the incidence of cardiac and cerebral-vascular complications, in those deceased with ChPN and AH, was 6 times greater than the first and uremia and urosepsis--considerably less frequent.
