Late Consequences of Acute Coronary Syndromes: Global Registry of Acute Coronary Events (GRACE) Follow-up.

Purpose: Short-term outcomes have been well characterized in acute coronary syndromes; however, longer-term follow-up for the entire spectrum of these patients, including ST-segment-elevation myocardial infarction, non-ST-segment-elevation myocardial infarction, and unstable angina, is more limited. Therefore, we describe the longer-term outcomes, procedures, and medication use in Global Registry of Acute Coronary Events (GRACE) hospital survivors undergoing 6-month and 2-year follow-up, and the performance of the discharge GRACE risk score in predicting 2-year mortality.

Methods: Between 1999 and 2007, 70,395 patients with a suspected acute coronary syndrome were enrolled.

Results of a nationwide screening for Anderson-Fabry disease among dialysis patients.

Anderson-Fabry disease is possibly underdiagnosed in patients with end-stage renal disease. Nationwide screening was therefore undertaken for Anderson-Fabry disease among dialysis patients in Austria. Screening for alpha-galactosidase A (AGAL) deficiency was performed by a blood spot test.

Search for occult secondary osteoporosis: impact of identified possible risk factors on bone mineral density.

Objectives: To determine whether the use of more elaborate diagnostic tests can identify possible risk factors for secondary osteoporosis and to evaluate the impact of these possible risk factors on the severity of bone disease in the study population.

Design: Cross-sectional study.

Setting And Participants: We have investigated 377 subjects (285 females, 92 males) with osteoporosis (T-score less than -2.

Coronary anatomy predicts presence or absence of renal artery stenosis. A prospective study in patients undergoing cardiac catheterization for suspected coronary artery disease.

Aims: This study aimed to determine the prevalence of renal artery stenosis (RAS) and associated risk factors in patients undergoing cardiac catheterization for suspected coronary artery disease (CAD).

Methods: One hundred and seventy-seven consecutive patients (62 females) with a serum creatinine concentration <2.0mg.

beta-2 Adrenergic receptor variants affect resting blood pressure and agonist-induced vasodilation in young adult Caucasians.

Recent evidence suggests that the prodownregulatory Gly16 allele of the beta-2 adrenergic receptor (beta-2 AR) is associated with essential hypertension in African Caribbeans. To further investigate the effect of the glycine (Gly)16 and arginine (Arg)16 beta-2 AR variants on hemodynamics, we investigated the agonist-mediated in vivo vasodilation in normotensive Austrian Caucasians and analyzed the results with respect to the Gly16/Arg16 polymorphism. Fifty-seven normotensive men, 20 to 32 years of age with body mass index of 18.

A software package for non-invasive, real-time beat-to-beat monitoring of stroke volume, blood pressure, total peripheral resistance and for assessment of autonomic function.

The goal of the present study was to develop and evaluate algorithms for non-invasive, real-time, beat-to-beat monitoring of stroke index (SI), blood pressure (BP) and total peripheral resistance index (TPRI) which has a menu-driven interface, suitable for routine use by unskilled staff. In addition, it was our aim to include a meta-analysis for the evaluation of autonomic function derived from the above haemodynamic data. This includes spectral analysis of heart rate (HR), BP, SI and TPRI and the automatic calculation of baroreceptor reflex sensitivity.

Essential hypertension in African Caribbeans associates with a variant of the beta2-adrenoceptor.

Populations of West African ancestry dwelling in Western communities exhibit greater prevalence of human essential hypertension and higher rates of end-organ damage. The sympathetic nervous system influences cardiac output, vascular tone, renal sodium reabsorption, and renin release and could be implicated in enhanced vascular responsiveness observed in African hypertensives. Such an effect could arise from genetic variants that alter agonist response of alpha-adrenoceptors, leading to enhanced vasoconstriction, or attenuate beta2-adrenoceptor-mediated vasodilatation.
