/baseline peak and mean velocity ratios were used for evaluating blood flow reserve in the LAD. Heart rate and arterial pressure values were similar in the 3 groups at baseline and during infusion. Baseline and -related flow velocities were comparable in the 3 groups. Peak and mean diastolic ...
Luijkx found a balanced increase of LV and RV chamber volume in relationship in the athlete heart [51]; a large meta-analysis of the literature had a similar conclusion [49]. RV and LV systolic function is commonly characterized by ejection fraction, but this parameter is known to show the ...
Heart rate variability (HRV) analysis has shown promise as a valuable complementary tool for clinical assessment in trauma cases. This study aims to evaluate the utility of HRV in monitoring different severities of hemorrhagic shock (HS) and its correlation with traditional hemodynamic and metabolic ...
Cardiovascular magnetic resonance (CMR) enables assessment and quantification of morphological and functional parameters of the heart, including chamber size and function, diameters of the aorta and pulmonary arteries, flow and myocardial relaxation times. Knowledge of reference ranges (“normal values”) ...

Similar to resistance training, aerobic endurance training has been shown to elicit muscle hypertrophy and growth.[19]Konopka and Harbor explain that effective aerobic exercise, defined as maintaining heart rate reserve >70% for 30 to 45 minutes at least 4 days per week, has th...
[1]. TTE is usually combined with vasodilator stress testing to assess coronary flow velocity reserve (CFVR) as the ratio of peak/rest CFV, as recommended by general cardiology guidelines [2,3]. Recently, emphasis has been placed on absolute values of resting CFV, which may help with ...
An increased serum progesterone-to-estradiol ratio on the day of human chorionic gonadotropin administration does not have a negative impact on clinical pregnancy rate in women with normal ovarian reserve treated with a long gonadotropin releasing hormone agonist protocol...
