Functional evaluation of patients with chronic pulmonary hypertension
No full textThe importance of studying the pathophysiological bases and clinical correlates of exercise limitation in patients with pulmonary arterial hypertension (PAH) is well established. Two modes of exercise testing, the 6-min walk test (6MWT) and the cardiopulmonary exercise test (CPET), are currently proposed for diagnostic, therapeutic and prognostic finalities. The 6MWT is inexpensive, feasible and is thought to better reproduce daily life activities and to reliably detect therapeutic benefits. CPET requires the patient's maximal effort and does not provide a reliable quality of life measure. It is, however, highly reproducible and provides remarkable insights into the pathophysiological mechanisms that lead to exercise intolerance. Due to the limited experience accumulated, CPET is not actually advised for the routine assessment and for the overall clinical decision making of PAH patients. In this review we critically address the knowledge currently acquired on these techniques
181 QUESTIONS & ANSWERS IN HEART FAILURE Heart failure 181 Questions & Answers.
No full textOn decided to be innovative and original, and, with liberal recourses to some much-needed Italian winw, the concept of 181 Question and answers in Heart failure took shape. The idea was to write a practical book posing the questions we ask ourselvels every day in our profession, and to pool our experience to provide-preferably palatable- food for thought for today's harried cardiologist

No full textWe investigated the nutritional adequacy and energy availability in 57 normal-weight patients with chronic heart failure (HF) and 49 matched healthy sedentary subjects. We found that the chronic HF patients had a higher total energy expenditure (1,700 +/- 53 vs 1,950 +/- 43 kcal/day; p <0.01), a negative calorie balance (104 +/- 35 vs -186 +/- 40 kcal/day; p <0.01), a negative nitrogen balance (2.2 +/- 0.5 vs -1.7 +/- 0.4 g/day; p <0.01), and a hypercatabolic hormonal status (cortisol/insulin ratio 32 +/- 1.7 vs 65 +/- 5.1; p <0.01). We conclude that patients with chronic HF had an inadequate calorie intake to support energetic needs for daily activities, with consequent important protein breakdown that causes muscular wastin
