Clinical and echocardiographic correlations of exercise-induced pulmonary hypertension in systemic sclerosis: A multicenter study

BACKGROUND: Patients with systemic sclerosis (SSc) are at risk for developing pulmonary hypertension, which is associated with a poor prognosis. Exercise Doppler echocardiography enables the identification of exercise-induced increase in pulmonary artery systolic pressure (PASP) and may provide a thorough noninvasive hemodynamic evaluation. AIM: The aim of this study was to evaluate the clinical and echocardiographic determinants of exercise-induced increase in PASP in a large population of patients with SSc. METHODS: We selected 164 patients with SSc (age 58 \ub1 13 years, 91% female) with normal resting PASP (<40 mm Hg) who underwent a comprehensive 2-dimensional and Doppler echocardiography and graded bicycle semisupine exercise Doppler echocardiography. Pulmonary artery systolic pressure, cardiac output, and pulmonary vascular resistance (PVR) were estimated noninvasively. Cutoff values of PASP 6550 mm Hg and PVR 653.0 Wood Units at peak exercise were considered a significant exercise-induced increase in PASP and PVR, respectively. RESULTS: Sixty-nine (42%) patients showed a significant exercise-induced increase in PASP. Among them, peak PVR 653 Wood Units was present only in 11% of patients, about 5% of the total population. Univariate analysis showed that age, presence of interstitial lung disease, and both right and left diastolic dysfunction are predictors of peak PASP 6550 mm Hg, but none of these parameters predict elevated peak PVR. CONCLUSIONS: Exercise-induced increase in PASP occurs in almost one-half of patients with SSc with normal resting PASP. Peak exercise PASP is affected by age, interstitial lung disease, and right and left ventricular diastolic dysfunction and, only in 5% of the patients, is associated with an increase in PVR during exercise, suggesting heterogeneity of the mechanisms underlying exercise-induced pulmonary hypertension in SSc

Drug prescription appropriateness in hospitalized older patients: 15-year results and lessons from a countrywide register.

The global increase of aging with the related increase of multiple noncommunicable diseases is inevitably accompanied by the associated issue of multimorbidity and polypharmacy. The latter is not without peculiar consequences on health, because it has been shown to be associated with drug-related adverse events, mainly due to poor prescription appropriateness and drug-drug interactions. To contribute to tackle this gigantic problem, a registry of drug dispensation in hospitalized older patient has been initiated in Italy in 2008. Through the last 15 years, data on nearly 11,000 older people have been accrued during their hospital stay in internal medicine and geriatric wards. This review article summarizes the main findings obtained, and how these data contribute to tackle the issue of appropriateness of drug prescription and the need of deprescribing in hospitalized older people affected by the most common noncommunicable diseases
