Chronic ‘Exercise Deficiency’ Linked to HFpEF

Chronic lack of exercise — dubbed "exercise deficiency" — is associated with cardiac atrophy, reduced cardiac output and chamber size, and diminished cardiorespiratory fitness (CRF) in a subgroup of patients with heart failure with preserved ejection fraction (HFpEF), researchers say. Increasing the physical activity levels of these sedentary individuals could be an effective preventive strategy, particularly for those who are younger and middle-aged, they suggest. Thinking of HFpEF as an exercise deficiency syndrome leading to a small heart "flies in the face of decades of cardiovascular teaching, because traditionally, we've thought of heart failure as the big floppy heart," Andre La Gerche, MBBS, PhD, of the Baker Heart and Diabetes Institute in Melbour...

Exercise Limitations in COPD — More Inhalers?

Chronic obstructive pulmonary disease (COPD) is defined by airway obstruction and alveolar damage caused by exposure to noxious air particles. The physiologic results include varying degrees of gas-exchange abnormality and mechanical respiratory limitation, often in the form of dynamic hyperinflation. There's a third major contributor, though ─ dyspnea. That's right, skeletal muscle deconditioning. Only one of these abnormalities responds to inhalers. When your patients with COPD report dyspnea or exercise intolerance, what do you do? Do you attempt to determine its character to pinpoint its origin? Do you quiz them about their baseline activity levels to quantify their conditioning? I bet you get right to the point and order a cardiopulmonary exercise test (CPET). That way...
