[Blood and serum viscosity in cardiologic X syndrome]

The aim of this study was to explore if are there blood rheological disturbances in cardiac syndrome X. Two groups were examined: 23 patients (aged 41 divided by 72 years) suffering from cardiac syndrome X (typical anginal pain positive stress test and no lesion in coronary angiograms) and 20 healthy (aged 32 divided by 57 years). Blood samples were drawn from the cubital vein prior to the angiogram. Blood viscosity measurements were performed using the Brookfield Cone/Plate Viscosimeter at 150 s-1 shear rate, and by means of low-shear Contraves viscometer at 1 s-1 (a)nd 4.59 s-1 shear rates. The plasma viscosity was measured by means of Ubbelohde's capillary viscometer. Besides the viscometric examinations the total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides and glucose plasma concentration as well as blood morphology and ESR were determined. All rheological measurements were carried out at the temperature of 37 degrees C immediately after blood drawing. It was stated that blood and plasma viscosity were significantly elevated in syndrome X compared with the control group (p < 0.001).

The examinations indicate that in patients suffering from Cardiological Syndrome X the whole blood and plasma viscosity are increased.
