The spectrum and prevalence of arrhythmia in different clinical pulmonary hypertension groups in Chinese population.

Background: Arrhythmia is not uncommon among pulmonary hypertension (PH) population, and may be associated with disease severity.

Hypothesis: To investigate different spectrums and prevalence of arrhythmias in different clinical PH groups in Chinese population.

Methods: Patients diagnosed with PH between April 15, 2019, and August 2, 2021, were enrolled prospectively.

[Clinical observation of cardiopulmonary exercise test in patients with idiopathic pulmonary arterial hypertension].

Objective: To explore the exercise characteristics of patients with idiopathic pulmonary arterial hypertension (IPAH).

Methods: From November 2010 to September 2012 , 76 consecutive IPAH patients and 24 healthy controls from Fuwai Cardiovascular Hospital were enrolled to undergo cardiopulmonary exercise testing. The exercise parameters were compared.

[Value of cardiopulmonary exercise test in assessment of cardiac function of patients with pulmonary hypertension].

Objective: To explore the role of peak oxygen consumption in assessment of heart function of patients with pulmonary hypertension.

Methods: From September 2010 to April 2012, 101 patients [29 male, mean age: (32.6 ± 11.

[The effects of noninvasive positive pressure ventilation treatment on plasma concentration of amino terminal-pro brain natriuretic peptide in congestive heart failure in patients with sleep apnea].

Objective: Sleep apnea (SA) exerts adverse effects in patients with congestive heart failure (CHF). Amino terminal-pro brain natriuretic peptide (NT-proBNP) is a useful target of CHF treatment. The purpose of this study was to assess the short-term effect of positive pressure ventilation (PPV) on the plasma concentration of NT-proBNP in patients with both CHF and SA.
