“…Findings from 2 large right heart catheterization (RHC) registries2, 3 and numerous other smaller clinical studies4, 5 have demonstrated that mPAP of >19 mm Hg (previously termed “borderline pulmonary hypertension [PH]”) is an independent risk factor for increased mortality. This observation indicates that the traditional mPAP threshold for defining PH of ≥25 mm Hg may be insufficient.…”

BackgroundRecent studies have demonstrated a continuum in clinical risk related to mean pulmonary artery pressure that begins at >19 mm Hg, which is below the traditional threshold used to define pulmonary hypertension (PH) of 25 mm Hg. Because of the implications on patient diagnosis and prognosis, the generalizability and validity of these data need further confirmation.Methods and ResultsDatabases were searched from inception through January 31, 2018, to identify studies comparing all‐cause mortality between patients with mildly elevated mean pulmonary artery pressure near but <25 mm Hg versus the referent group. The meta‐analysis included 15 nonrandomized studies and 16 482 patients (7451 [45.2%] with measured or calculated mean pulmonary artery pressure of 19–24 mm Hg by right heart catheterization [n=6037] and echocardiography [n=1414] [mild PH]). The mean duration of follow‐up was 5.2 years. Compared with the referent group, mild PH was associated with an increased risk of mortality (risk ratio, 1.52; 95% confidence interval, 1.32–1.74; P<0.001; I2=47%). Secondary analysis using risk‐adjusted time‐to‐event estimates showed a similar result (hazard ratio, 1.19; 95% confidence interval, 1.09–1.31; P<0.001; I2=42%). The findings were consistent between subgroups of right heart catheterization and echocardiography studies (P interaction>0.05). There was evidence of publication bias; however, this did not influence the risk estimate (Duval and Tweedie's trim and fill adjusted risk ratio, 1.34; 95% confidence interval, 1.15–1.56).ConclusionsThe risk of mortality is increased in patients with mild PH, defined as measured or calculated mean pulmonary artery pressure >19 mm Hg. These data emphasize a need for diagnosing patients with mild PH with consideration to enrollment in PH clinical studies investigating pharmacological and nonpharmacological interventions to attenuate clinical risk and improve outcomes.

“…However, 20% of subjects without a TRV had a mPAP >35 mm Hg, which would have remained undetected had they not also been referred for RHC. Moreover, detecting even mild elevations in pulmonary pressure is important based on recent reports showing that “borderline” values of mean pulmonary pressure are reproducibly associated with increased adjusted mortality 14, 15. Additionally, the no‐TRV group may be earlier in the disease process relative to the TRV group and may in fact develop more readily measurable TRV Doppler signals over time.…”

BackgroundTransthoracic echocardiography (TTE) is used to estimate pulmonary artery systolic pressure, but an adequate tricuspid regurgitation velocity (TRV) needed to calculate pulmonary artery systolic pressure is not always present. It is unknown whether the absence of a measurable TRV signifies normal pulmonary artery pressure.Methods and ResultsWe extracted hemodynamic, TTE, and clinical data from Vanderbilt's deidentified electronic medical record in all patients referred for right heart catheterization between 1998 and 2014. Pulmonary hypertension (PH) was defined as mean pulmonary artery pressure ≥25 mm Hg. We examined the prevalence and clinical correlates of PH in patients without a reported TRV. We identified 1262 patients with a TTE within 2 days of right heart catheterization. In total, 803/1262 (64%) had a reported TRV, whereas 459 (36%) had no reported TRV. Invasively confirmed PH was present in 47% of patients without a reported TRV versus 68% in those with a reported TRV (P<0.001). Absence of a TRV yielded a negative predictive value for excluding PH of 53%. Right ventricular dysfunction, left atrial dimension, elevated body mass index, higher brain natriuretic peptide, diabetes mellitus, and heart failure were independently associated with PH among patients without a reported TRV.Conclusions PH is present in almost half of patients without a measurable TRV who are referred for both TTE and right heart catheterization. Clinical and echocardiographic features of left heart disease are associated with invasively confirmed PH in subjects without a reported TRV. Clinicians should use caution when making assumptions about PH status in the absence of a measurable TRV on TTE.
