Can Inhaled Nitric Oxide Response Predict Tolerance to Therapies and Survival in Patients With Combined Precapillary and Postcapillary Pulmonary Hypertension? Am J Cardiol 2023; 207:363-369. [PMID: 37778225 DOI: 10.1016/j.amjcard.2023.09.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 09/04/2023] [Accepted: 09/06/2023] [Indexed: 10/03/2023]
Abstract
Inhaled nitric oxide (iNO) relaxes the pulmonary circulation and variably increases the left ventricular preload and pulmonary artery wedge pressure (PAWP)-hemodynamic information that may help guide treatment decisions and assess prognosis in patients with combined precapillary and postcapillary pulmonary hypertension (PH). We included consecutive patients with combined precapillary and postcapillary PH (mean pulmonary artery pressure >20 mm Hg, PAWP >15 mm Hg, and pulmonary vascular resistance [PVR] >2 Woods unit [WU]) who underwent right-sided cardiac catheterization with iNO at the Cleveland Clinic Pulmonary Vascular Disease program between 2017 and 2022. We included 104 patients with baseline PAWP and PVR of 22.2 ± 4.2 mm Hg and 6.1 ± 3.2 WU, respectively. Pulmonary arterial hypertension (PAH) with postcapillary component and PH left heart disease with precapillary component were identified in 27 (26%) and 77 patients (74%), respectively. No side effects were noted during the administration of iNO. During iNO, the PVR decreased 1.1 ± 1.4 WU and the PAWP increased 1.3 ± 3.7 mm Hg. A more pronounced increase in PAWP with iNO was associated with a decrease in PVR (R -0.35, p <0.001) and increase in stroke volume (R 0.20, p = 0.046). Tolerance to PAH-specific medications, overall survival, and heart failure hospitalizations were not significantly associated with the change in PAWP or PVR with iNO. In conclusion, in patients with combined precapillary and postcapillary PH, iNO challenge is safe and caused a significant decrease in PVR, with an increase in PAWP. The changes in PAWP and PVR during iNO administration were not associated with tolerance to PAH-specific medications, heart failure-related hospitalization, or survival.

Cutaneous iontophoresis of vasoactive medications in patients with scleroderma-associated pulmonary arterial hypertension. Microcirculation 2021; 29:e12734. [PMID: 34741773 DOI: 10.1111/micc.12734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Revised: 10/26/2021] [Accepted: 10/30/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND It remains unknown whether the cutaneous microvascular responses are different between patients with scleroderma-associated pulmonary arterial hypertension (SSc-PAH) and SSc without pulmonary hypertension (PH). METHODS We included 59 patients with SSc between March 2013 and September 2019. We divided patients into 4 groups: (a) no PH by right heart catheterization (RHC) (n = 8), (b) no PH by noninvasive screening tests (n = 16), (c) treatment naïve PAH (n = 16), and (d) PAH under treatment (n = 19). Microvascular studies using laser Doppler flowmetry (LDF) were done immediately after RHC or at the time of an outpatient clinic visit (group b). RESULTS The median (IQR) age was 59 (54-68) years, and 90% were females. The responses to local thermal stimulation and postocclusive reactive hyperemia, acetylcholine, and sodium nitroprusside iontophoresis were similar among groups. The microvascular response to treprostinil was more pronounced in SSc patients without PH by screening tests (% change: 340 (214-781)) compared with SSc-PAH (naïve + treatment) (Perfusion Units (PU) % change: 153 (94-255) % [p = .01]). The response to A-350619 (a soluble guanylate cyclase (sGC) activator) was significantly higher in patients with SSc without PH by screening tests (PU % change: 168 (46-1,296)) than those with SSc-PAH (PU % change: 22 (15-57) % [p = .006]). The % change in PU with A350619 was directly associated with cardiac index and stroke volume index (R: 0.36, p = .03 and 0.39, p = .02, respectively). CONCLUSIONS Patients with SSc-PAH have a lower cutaneous microvascular response to a prostacyclin analog treprostinil and the sGC activator A-350619 when compared with patients with SSc and no evidence of PH on screening tests, presumably due to a peripheral reduction in prostacyclin receptor expression and nitric oxide bioavailability.

RDW-based clinical score to predict long-term survival in community-acquired pneumonia: a European derivation and validation study. Intern Emerg Med 2021; 16:1547-1557. [PMID: 33428112 PMCID: PMC7797708 DOI: 10.1007/s11739-020-02615-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Accepted: 12/18/2020] [Indexed: 11/29/2022]
Abstract
An excess long-term mortality has been observed in patients who were discharged after a community-acquired pneumonia (CAP), even after adjusting for age and comorbidities. We aimed to derive and validate a clinical score to predict long-term mortality in patients with CAP discharged from a general ward. In this retrospective observational study, we derived a clinical risk score from 315 CAP patients discharged from the Internal Medicine ward of Cuneo Hospital, Italy, in 2015-2016 (derivation cohort), which was validated in a cohort of 276 patients discharged from the pneumology service of the Barakaldo Hospital, Spain, from 2015 to 2017, and from two internal medicine wards at the Turin University and Cuneo Hospital, Italy, in 2017. The main outcome was the 18-month follow-up all-cause death. Cox multivariate analysis was used to identify the predictive variables and develop the clinical risk score in the derivation cohort, which we applied in the validation cohort. In the derivation cohort (median age: 79 years, 54% males, median CURB-65 = 2), 18-month mortality was 32%, and 18% in the validation cohort (median age 76 years, 55% males, median CURB-65 = 2). Cox multivariate analysis identified the red blood cell distribution width (RDW), temperature, altered mental status, and Charlson Comorbidity Index as independent predictors. The derived score showed good discrimination (c-index 0.76, 95% CI 0.70-0.81; and 0.83, 95% CI 0.78-0.87, in the derivation and validation cohort, respectively), and calibration. We derived and validated a simple clinical score including RDW, to predict long-term mortality in patients discharged for CAP from a general ward.
