  • Natural history of patients with unoperated atherosclerotic carotid artery disease--results from a retrospective study
  • 1993

    • The natural history of carotid artery disease was studied in a retrospective study of 609 angiograms performed during 1969-1979 on patients who had subsequently not been operated on. The indication for angiography differed, but was aimed at clarifying suspected cerebrovascular events. 578 patients could be followed-up after a median time of 10.4 years (0-22). The median survival time after angiography was 9.7 years for the 355 men and 12.8 years for the 223 women (p = 0.0099). Internal carotid stenosis of > 50% was seen in 9.0% (bilaterally in 2.2%), a stenosis > 75% in 4.5% (bilaterally in 0.9%) and occlusion in 9% (bilaterally in 0.7%). Ulceration was present in 10.7% (bilaterally in 1.6%). 26.5% of the patients had a cerebrovascular event during follow-up, of which 31.4% had transient ischaemic attack or amaurosis fugax. Survival was not influenced by the degree of stenosis, but presence of arteriosclerotic carotid artery disease significantly reduced the median survival time from 11 to 3 years. The main cause of death for men was myocardial infarction (27.7%) and for women a cerebrovascular event (27.8%), a significant difference. From this study, in selected patients it can be concluded that the annual frequency of cerebrovascular events was low, approaching frequencies reported in asymptomatic patients. The cause of death differed between men and women, with more cardiac deaths among men and more cerebrovascular deaths among women.

  • Cost/benefit aspects on thromboprophylaxis
  • 1993
  • Ingår i: Haemostasis. - 0301-0147. ; 23:Suppl. 1, s. 15-19
  • Tidskriftsartikel (refereegranskat)abstract
    • Several studies have shown thromboprophylaxis of any kind to be more cost-effective than no prophylaxis or general diagnostic surveillance and selective treatment. Little has been written on low molecular weight heparins from the cost-effectiveness point of view. This preliminary study shows low molecular weight heparin to be more cost-effective than standard low-dose heparin in most situations of prophylaxis.

  • Determination of urinary N-acetyl-beta-glucosaminidase in patients with hypertension and renal artery stenosis
  • 1993
  • Ingår i: Journal of Internal Medicine. - : Wiley. - 1365-2796 .- 0954-6820. ; 234:3, s. 281-285
  • Tidskriftsartikel (refereegranskat)abstract
    • The purpose of the study was to measure the urinary excretion of N‐acetyl‐beta‐glucosaminidase (U‐NAG) in patients suspected of having renovascular hypertension and to compare the enzyme excretion before and after active intervention with operation or percutaneous transluminal renal angioplasty (PTRA). Eighty‐one patients with severe, therapy‐resistant hypertension were examined with regard to renal artery stenosis (RAS). At least one significant renal artery stenosis was found in 61 patients, whilst the remaining 20 patients were classified as having essential hypertension. Enzyme levels were found to be significantly higher in RAS patients as compared with patients with severe hypertension lacking significant renal artery stenosis, 0.66 (0.41–0.91, median value, 1st and 3rd quartiles) versus 0.35 (0.27–0.54); P < 0.01. Both groups of patients had significantly higher U‐NAG values than a healthy reference population (0.2, 0.13–0.27; P < 0.01). Forty of the RAS patients were randomized to surgery or PTRA and followed prospectively for 2 years. After either renal vascular surgery or PTRA a significant rise in U‐NAG excretion was observed 7–10 days after treatment. Urinary NAG excretion remained elevated during long‐term follow‐up. It is suggested that U‐NAG should be determined in patients with therapy‐resistant hypertension with suspicion of renal artery stenosis.
