... intake has a beneficial effect on muscle mass has not been demonstrated. In this study, we investigated an association between changes of normalized protein catabolic rate (nPCR), as a proxy for protein intake and percent creatinine generation rate (%CGR), as a proxy for muscle mass in patients receiving...

... Abstract Several cohort studies have shown that increasing heart rate (HR) is a predictor of cardiovascularmortality in apparently healthy subjects, independent of several other potentialcoronary risk factors. Increased resting HR is also a well-known negative prognostic sign inpatients...

... Abstract Psychoanalytical initial interviews were monitored by cameras while, at the same time, both the patient’s and the doctor’s ECGs were telemetrically recorded. Changes of heart rate were related to intra- aswell as interpersonal occurrences during the interview. Both concordant...

... Abstract The authors attempted to reduplicate the Lacey phenomenon of heart rate acceleration during the performance of an interiorized mental task and its maintenance in time. For this purpose they resorted to the pavlovian conditioning paradigm. The heart-rate response was obtained...

... Abstract Heart rate reduction is becoming a new strategy to treat coronary patients. The developmentof heart-rate-lowering drugs, with a more specific activity than Β-blockers, coincideswith the detection of the sinoatrial pacemaker I f current. The first selective I f inhibitor thathas been...

... Abstract Heart rate is a major determinant of myocardial oxygen consumption. There is ampleevidence of an association between high heart rate and poor outcome in numerous clinicalsettings. Experimental studies in monkeys have shown a link between increased heart rateand development...

... Abstract Heart rate slowing is generally accepted as effective for angina prevention but thisapproach has not been rigorously evaluated as no pure heart rate slowing treatment has beenavailable. With the identification of the I f current, the primary modulator of heart rate, and useof...

... and decreases myocardial perfusion. Β-Blockers are effective at reducing anginalsymptoms largely by decreasing heart rate. Physician use and patient compliance may be limitedby the side effects of Β-blockers which include fatigue, depression and sexual dysfunction.Heart rate reduction can also be obtained...

... Abstract Heart failure is a major health problem, and is one of the few cardiovascular diseasesthat increased its prevalence over the last decade. Increased heart rate, generally observed inpatients with heart failure, is involved in the deterioration of cardiac pump function.However...
