During a 10-year period, intraparenchymal aneurysms were found in 38 of 748 patients at selective abdominal angiography with magnification technique. According to strict criteria, 17 patients were classified as suffering from necrotizing vasculitis of the polyarteritis nodosa group (PAN), 7 from severe arterial hypertension, and 3 from rheumatoid arthritis.(More)
Three patients with multiple renal complications of polyarteritis nodosa are described. The arteriographic findings in these patients were multiple arterial aneurysms and tissue infarctions, with the development of spontaneous intrarenal, subcapsular, and perirenal hemorrhagic complications. Computed tomography showed the hemorrhages and multiple renal(More)
OBJECTIVE To evaluate the accuracy of ultrasonography (US) in the detection and quantification of arterial involvement in Takayasu's arteritis (TA). METHODS The common carotid and subclavian arteries, and the abdominal aorta of 15 patients with TA were studied by Color Doppler (CD) US and Doppler spectral analysis and compared with angiography. RESULTS(More)
Over a 25-year period 29 patients underwent 49 vascular procedures due to arterial insufficiency or vascular complications caused by Takayasu's arteritis. In bypass operations 36 grafts were inserted. The 5-year patency rates were 53% when grafts were used for patients with the active disease stage and 88% during the inactive disease stage (p = 0.059). The(More)
OBJECTIVE To assess the feasibility and potential diagnostic usefulness of arterial ultrasonography in Takayasu's arteritis. METHODS The total wall, intimal + medial, and adventitial thickness of the common carotid, subclavian and common femoral arteries, and of the abdominal aorta, were examined by B mode ultrasonography in 16 patients with Takayasu's(More)
The prognostic value of discharge ECG was studied in 457 patients after their first acute myocardial infarction. Thirteen different ECG variables were studied on the discharge ECG. When cumulative 4-year survival rates were calculated by standard life-table method for each variable individually, the following variables had statistically significant(More)
Even at low doses, alcohol has been reported to impair left ventricular pump function. To characterize further the effects of alcohol on the normal cardiovascular system, using the Swan-Ganz thermodilution catheter, we studied 6 healthy physicians, aged 27-36 years, while they were lightly intoxicated. Within a period of 30 min the subjects ingested 0.5(More)
OBJECTIVES Atrial fibrillation (AF) is the most common arrhythmia in emergency rooms (ER). We surveyed the clinical characteristics and quality of care of AF patients in three emergency rooms in Helsinki, Finland. DESIGN Observational data of the treatment of 179 consecutive symptomatic AF patients were prospectively collected. The quality of care was(More)
BACKGROUND Atrial fibrillation (AF) is a common arrhythmia that causes numerous visits to emergency departments (ED). The aim of the FinFib2 study was to evaluate whether treatment of patients with AF in ED is consistent with the contemporary European Society of Cardiology (ESC) management guidelines. Here we report the results of antiarrhythmic drug(More)
A case of polyarteritis nodosa with the acute complications of multiple bilateral real artery dissection, perirenal haemorrhage and kidney infarction is described. The diagnosis of polyarteritis nodosa was established on the basis of angiographical and clinical findings. Follow-up arteriograms and CT-findings after prednisone therapy are discussed.
