The IABP-SHOCK II risk score can be easily calculated in daily clinical practice and strongly correlated with mortality in patients with infarct-related CS. It may help stratify patient risk for short-term mortality and might, thus, facilitate clinical decision making. (Intraaortic Balloon Pump in Cardiogenic Shock II [IABP-SHOCK II]; NCT00491036).

Controversial data exist on acute and chronic effects of competitive sports on central hemodynamics and arterial stiffness. We investigated chronic as well as acute training effects in professional rowers. The trial was planned as a non-randomized, controlled pilot-study comparing athletes and controls. 13 German national team rowers (24.1 ± 1.5 years) and 12 controls (23.8 ± 0.8 years) participated. Aortic, brachial hemodynamics and arterial stiffness were measured (Arteriograph, TensioMed(®), Hungary) before and after a standardized exercise test. Chronic heart rate (49 [Formula: see text] 2 bpm versus 70 [Formula: see text] 2 bpm, p < 0.05) as well as brachial diastolic pressure (65 [Formula: see text] 2 mmHg versus 74 [Formula: see text] 2 mmHg, p < 0.05) was significantly lower in rowers. Physical power (305 [Formula: see text] 63 versus 158 [Formula: see text] 60 W, p < 0.001) was better. Chronic aortic pulse pressure (41.6 [Formula: see text] 6.0 versus 35.2 [Formula: see text] 3.8 mmHg; p < 0.01) and AIx (9.1 [Formula: see text] 5.4 versus 7.0 [Formula: see text] 10.2; p < 0.01) were significantly higher in athletes. After the all-out test (acute effects) pulse wave velocity (rowers: 6.6 [Formula: see text] 1.2 m s(-1) versus 7.8 [Formula: see text] 1.6 m s(-1), p < 0.001; control group 6.0 [Formula: see text] 0.4 m s(-1) versus 8.0 [Formula: see text] 1.4 m s(-1), p  =  0.005) and heart rate (rowers: 49 [Formula: see text] 2 bpm versus 91 [Formula: see text] 3 bpm, p < 0.001; control group 70 [Formula: see text] 2 bpm versus 92 [Formula: see text] 4 bpm, p < 0.001) increased significantly in both groups. The controls' aortic AIx (7.0 [Formula: see text] 10.2 versus 2.0 [Formula: see text] 6.0; p < 0.01) decreased significantly after exercise. Professional rowers showed higher chronic aortic pulse pressure and arterial stiffness. Given the risk associated with elevated aortic pulse pressure and AIx for development of cardiovascular diseases, longterm observations of professional rowers are needed with respect to arterial stiffness and prognosis. Furthermore the acute effects need additional research.

Two hundred twenty patients were randomly assigned to receive either ceforanide or cephalothin as perioperative antibiotic prophylaxis during cardiovascular surgery. More infections were seen among cephalothin recipients (8 deep, 32 total) than among ceforanide recipients (1 deep, 17 total). Among patients who had only coronary artery bypass grafting, more cephalothin recipients had infection than did ceforanide recipients (19 of 82 as opposed to 7 of 83; p = 0.001; relative risk, 2.7; 95% confidence interval, 1.22 to 6.18). The difference between the two regimens was attributable to fewer blood, wound, and urinary tract infections. Among patients who had other procedures, there was no difference in the efficacy of the two regimens. Cephalothin recipients who developed wound or blood stream infections had lower antibiotic levels in their atrial appendages than recipients not developing such infections (p = 0.02). If one assumes that cephalothin does not increase the risk of infection, then these data show that antibiotic prophylaxis prevents infection after coronary artery bypass surgery, and, in the dosages used, that ceforanide is superior to cephalothin.

Background Cardiac autonomic dysfunction after myocardial infarction identifies patients at high risk despite only moderately reduced left ventricular ejection fraction. We aimed to show that telemedical monitoring with implantable cardiac monitors in these patients can improve early detection of subclinical but prognostically relevant arrhythmic events. MethodsWe did a prospective investigator-initiated, randomised, multicentre, open-label, diagnostic trial at 33 centres in Germany and Austria. Survivors of acute myocardial infarction with left ventricular ejection fraction of 36-50% had biosignal analysis for assessment of cardiac autonomic function. Patients with abnormal periodic repolarisation dynamics (≥5•75 deg²) or abnormal deceleration capacity (≤2•5 ms) were randomly assigned (1:1) to telemedical monitoring with implantable cardiac monitors or conventional follow-up. Primary endpoint was time to detection of serious arrhythmic events defined by atrial fibrillation 6 min or longer, atrioventricular block class IIb or higher and fast non-sustained (>187 beats per min; ≥40 beats) or sustained ventricular tachycardia or fibrillation. This study is registered with ClinicalTrials.gov, NCT02594488.
