Objective To analyze the classification and composition change of hospitalized patients with pulmonary hypertension (PH) in our hospital during recent 5 years.Methods This retrospective analysis was performed for hospitalized patients with PH between January 2009 and November 2013.Results A total of 1 003 patients diagnosed with PH were included,the PH-to-total discharged patients ratio was 2.30％.Majority PH (682,68.00％) was originated from congenital heart diseases (CHD-PH),11.67％ (117) from connective tissue diseases,11.26％ (113) from valvular heart diseases,4.99％ (50) from idiopathic,2.00％ (20) from respiratory diseases.The CHD-PH decreased gradually (P =0.041) while the VHD-PH increased gradually (P =0.017),especially in 2013.The percentage of right cardiac catheterization examination in this PH cohort was 18.64％ (187/1 003).Excluding CHD-PAH and VHD-PH,the ratio of right cardiac catheterization examination in PH patients was 40.38％ (84/208).Correct PH diagnosis by echocardiography was 74.00％ (187/253) according to right cardiac catheterization examination.A total of 186 PH patients received pulmonary vascular-targeted medication,84.90％ patients were treated with mono-therapy.Conclusion The clinical data from Xiangya hospital in 2009-2013 shows a stable composition of hospitalized patients with PH,the rate of right cardiac catheterization in these patients is low and the rate of specific target treatment of PH is high (mostly mono-therapy) excluding CHD-PAH and VHD-PH patients.

Five patients after prosthetic tricuspid valve, who received pacemaker implantation via coronary sinus during Oct, 2011 and Jul, 2014, were enrolled. Pacemakers were implanted via coronary vein in 5 patients without complications. The stimulation thresholds keep stable and symptoms (such as short breath and fatigue) were disappeared during the follow-up. For patients after tricuspid valve replacement, implantation of pacemaker via coronary sinus provides a safe and invasive approach and avoids opening the chest again.

Objective:To analyze the clinical characteristics of adult Chinese patients with syncope.Methods:This is a cross-sectional survey study. Patients with preliminary diagnosis of syncope in the Emergency Department, Geriatrics and Cardiology Outpatient Department, or Syncope Unit of 37 hospitals in 19 provinces, autonomous regions and the Hong Kong Special Administrative Region from June 2018 to March 2021 were included in this study. The clinical features of these patients with syncope were analyzed.Results:A total of 4 950 consecutive patients with syncope were included in this study. The age was (56.3±16.8)years, and 2 604 cases (52.6%) were male. The most common type of syncope was neurally mediated syncope (2 345 (47.4%)), followed by cardiac syncope (1 085 (21.9%)), orthostatic hypotensive syncope (311 (6.3%)), and unexplained syncope accounted for nearly one third (1 155 (23.3%)). Predisposing syncope was more common in patients under 65 years of age(2 066(72.4%) vs. 786(27.6%),χ 2=136.5, P<0.001). Presyncope was more common in patients with neurally mediated syncope (1 972(79.0%) vs.1 908(73.9%), χ 2=17.756, P<0.001). Premonitory symptoms were more common in women(1 837(80.0%) vs. 1 863(73.0%),χ 2=33.432, P<0.001). Presyncope syndrome was more common in patients under 65 years of age (2 482(77.8%) vs. 1 218(73.4%),χ 2=17.523, P=0.001). Cyanosis was more common in ≥65 years old patients (271(18.2%) vs. 369(12.7%), χ 2=23.235, P<0.001). Urinary incontinence was more common in old patients aged ≥65 years(252(15.2%) vs. 345(10.8%), χ 2=19.313, P<0.001). Family history was more common in patients with cardiogenic syncope compared with other types of syncope (264(24.3%) vs. 754(19.5%), χ 2=11.899, P=0.001). Hypertention(1 480(30.5%)), coronary heart disease(1 057(21.4%)), atrial flutter and atrial fibrillation(359(7.2%)), second degree atrioventricular block(236(4.8%)) were common complications of syncope. The proportion of patients with coronary heart disease was significantly higher in cardiac syncope than that of other types of syncope(417(38.4%) vs. 640(16.6%), χ 2=241.376, P<0.001). Other common complications included cerebrovascular diseases (551 (11.1%)) and diabetes mellitus (632(12.8%)). Conclusions:Neurally mediated syncope is the most common syncope in adult Chinese population. Patients with predisposing conditions and premonitory conditions are younger. Presyncope is more common in women. The proportion of family history and coronary heart disease is higher in patients with cardiogenic syncope.
