In pulmonary hypertension (PH), T wave inversions (TWI) are typically observed in precordial leads V1–V3 but can also extend further to the left-sided leads. To date, the cause and prognostic significance of this extension have not yet been assessed. Therefore, we aimed to assess the relationship between heart morphology and precordial TWI range, and the role of TWI in monitoring treatment efficacy and predicting survival. We retrospectively analyzed patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) treated in a reference pulmonary hypertension center. Patients were enrolled if they had a cardiac magnetic resonance (cMR) and 12-lead surface ECG performed at the time of assessment. They were followed from October 2008 until March 2021. We enrolled 77 patients with PAH and 56 patients with inoperable CTEPH. They were followed for a mean of 51 ± 33.5 months, and during this time 47 patients died (35.3%). Precordial TWI in V1–V6 were present in 42 (31.6%) patients, while no precordial TWI were observed only in 9 (6.8%) patients. The precordial TWI range correlated with markers of PH severity, including right ventricle to left ventricle volume RVEDVLVEDV (R = 0.76, p < 0.0001). The presence of TWI in consecutive leads from V1 to at least V5 predicted severe RV dilatation (RVEDVLVEDV ≥ 2.3) with a sensitivity of 88.9% and specificity of 84.1% (AUC of 0.90, 95% CI = 0.83–0.94, p < 0.0001). Presence of TWI from V1 to at least V5 was also a predictor of mortality in Kaplan–Meier estimation (p = 0.02). Presence of TWI from V1 to at least V5 had a specificity of 64.3%, sensitivity of 58.1%, negative predictive value of 75%, and positive predictive value of 45.5% as a mortality predictor. In patients showing a reduction in TWI range of at least one lead after treatment compared with patients without this reduction, we observed a significant improvement in RV-EDV and RV−EDVLV−EDV. We concluded that the extension of TWI to left-sided precordial leads reflects significant pathological alterations in heart geometry represented by an increase in RV/LV volume and predicts poor survival in patients with PAH and CTEPH. Additionally, we found that analysis of precordial TWI range can be used to monitor the effectiveness of hemodynamic response to treatment of pulmonary hypertension.

Sarcoidosis is a rare disease characterized by granulomatous inflammation in affected organs, primarily in lungs. Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) are easy and practical methods providing valuable information in diagnosis, severity, and prognosis of various diseases. Here, we aimed to investigate the association between NLR, PLR, and hematological parameters in sarcoidosis. The study was performed with 75 sarcoidosis patients and 92 controls. Patients’ NLR, PLR, and hematological parameters were compared with those of controls. Additionally, while differences between NLR and PLR were investigated in sarcoidosis patients, differences of extrapulmonary involvement, pulmonary hypertension (PH), and spontaneous remission between those with and without responses to treatment concerning stages were also assessed. NLR and PLR were significantly higher in sarcoidosis patients than controls. For NLR, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were found as 68, 61, 58, and 70% respectively, while sensitivity, specificity, PPV, and NPV for PLR were found as 72, 67, 63, and 74%, respectively. In sarcoidosis patients, NLR and PLR were significantly higher at stage-2 and -3 than at stage -1 and -4. There was a significant weak positive correlation between C-reactive protein (CRP) and NLR and PLR. Mean platelet volume (MPV), hemoglobin (Hgb), and mean corpuscular volume (MCV) were lower among patients than controls. A positive moderate correlation was detected between NLR and CD4/CD8 in blood, while there was a strong positive correlation between CD4/CD8 in bronchoalveolar lavage (BAL) and positive moderate correlation between PLR and CD4/CD8 in BAL. High NLR and PLR values were not significantly associated with pulmonary PH, spontaneous remission, response to treatment, and prognosis. The increase in PLR and NLR may be a guide for diagnoses of both sarcoidosis and lung parenchymal involvement. To use these entities as markers, our findings should be supported with prospective studies with larger samples.

The aims of the study were: (1) to evaluate the Ukrainian reality of survival in patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH); and (2) to determine predictors of death. A total of 281 patients were enrolled (52 [18.5%] with CTEPH, 229 [81.5%] with PAH). Long-term survival (Kaplan–Meier) and its predictors (Stepwise binary logistic regression and Cox's proportional hazards analyses) were evaluated in adult patients with PH (diagnosed by right heart catheterization [RHC]) within a prospective registry at a single referral center in Kyiv, Ukraine. Follow-up period was up to 51 months. The Kaplan–Meier survival rate for the total cohort was 93.3%, 86.8%, and 81.5% at one, two, and three years, respectively. Survival was better in patients with congenital heart diseases (CHD) in comparison with idiopathic PAH (long rank P = 0.002), connective tissue diseases (CTD; long rank P = 0.001) and CTEPH (long rank P = 0.04). Univariate Cox's predictors of death were: functional class IV (odds ratio [OR] = 4.94; 95% confidence interval [CI] = 2.12–11.48), presence of ascites (OR = 4.52; 95% CI = 2.21–9.24), PAH-CTD (OR = 3.07; 95% CI = 1.07–8.87), PAH-CHD (OR = 0.28; 95% CI = 0.11–0.68), HR on treatment > 105 beats per min (OR = 7.85; 95% CI = 1.83–33.69), office systolic BP < 100 mmHg (OR = 2.78; 95% CI = 1.26–6.1), 6MWT on treatment < 340 m (OR = 3.47; 95% CI = 1.01–12.35), NT-proBNP > 300 pg/mL (OR = 4.98; 95% CI = 1.49–16.6), right atrium square > 22 cm2 (OR = 14.2; 95% CI = 1.92–104.89), right ventricular square in diastole (OR = 1.08; 95% CI = 1.03–1.14), right ventricular square in systole (OR = 1.08; 95% CI = 1.02–1.11), mean pressure in right atrium per each 1-mmHg increase (OR = 1.02; 95% CI = 1.02–1.19). In multivariate Cox regression analyses only presence of ascites, office systolic BP < 100 mmHg, CHD etiology of PH, and NT-proBNP > 300 pg/mL were associated with survival.

Luminal Narrowing

Background: Wellens’ sign (WS) has been reported as a sign of critical proximal left anterior descending (PLAD) artery lesion with lumen narrowing greater than 90%. Wellens’ ECG signs for critical PLAD lesion are characterized by two different electrocardiogram (ECG) patterns: 1) Deep T wave inversion in leads V2, V3 (approximately 76% of cases); and 2) Biphasic T wave in leads V2, V3 (approximately 24% of cases). The prevalence of the ECG feature of WS ranges from 14-18%. The prognostic significance of WS in detecting significant coronary artery lesion defined as a luminal narrowing of the coronary vessel by more than 70% has not been well studied. Our study’s goal was to evaluate if WS is present in all patients with critical and significant PLAD lesions and is a sensitive or specific sign for critical and significant (>70% stenosis) PLAD lesions. Methods: All patients that underwent percutaneous coronary intervention (PCI) at an urban community hospital between January 2009 and December 2011 were included in the study. Log books from the cardiac catheterization laboratory were reviewed for all lesion types and corresponding demographics. The ECGs of patients with PLAD lesion were reviewed for T wave changes in precordial leads. Additionally, demographics such as age, gender and cardiovascular risk factors were recorded and analyzed. Descriptive statistics were used to analyze the data. Results: A total of 431 patients underwent PCI [emergent PCI 152 (35.3%), elective PCI 279 (64.7%)]. A total of 78 patients (18.1%) from both groups were found to have PLAD lesion. Fifty eight patients were male and 20 patients were female. The average age was 63.7 years. Critical PLAD lesion was present in 26 patients (33.3%) and 52 patients (66.7%) had PLAD lesion less than 90%. Of the 26 patients, 17 (65.4%) had WS. Wellens’ sign for predicting a critical PLAD had a sensitivity of 65.4%, a specificity of 69.2%, a positive predictive value (PPV) of 51.5% and a negative predictive value (NPV) of 80% (p = 0.0069, two-tailed Fisher’s exact test). Of the 42 patients who had PLAD lesion greater than 70%, 21 patients (50%) had WS. Of the 36 patients who had PLAD lesion less than 70%, 11 patients (30.6%) had WS. Wellens’ sign for predicting significant PLAD lesion in this cohort has a sensitivity of 50%, a specificity of 69.4%, a PPV of 65.6% and a NPV of 54.3% ( p = 0.1074). Conclusion: Our results corroborated prior studies showing that WS predicts the presence of critical (90%) PLAD lesion. Unfortunately, the value of WS for detecting/predicting significant CAD in PLAD was weak. Our results indicated that we were not able to predict the presence of significant (70%) PLAD lesion using WS. However, in appropriate clinical settings such as Non-ST elevation MI (NSTEMI) or unstable angina, Wellens’ sign may indicate the need for a more aggressive treatment strategy with patients proceeding to the cardiac catheterization suite sooner than later.

Abstract Background Negative T-waves are associated with sudden cardiac death (SCD) in the general population. Whether also low amplitude T-waves link to SCD risk in the general population is unknown. Purpose We investigated the prognostic significance of T-wave abnormalities in a general population cohort. Methods We evaluated the ECGs of 6584 Finnish general population subjects aged ≥30 years (mean age 51.2±13.9, 45.6% men) and classified them according to the T-wave morphology to 3 classes: 1) negative T-waves (negative T-wave with amplitude ≥0.1mV in ≥2 of the leads I, II, aVL, V4-V6), 2) low amplitude T-waves (negative or positive T-wave with amplitude &lt;0.1mV and amplitude ratio of T-wave and R-wave ≤10% in ≥2 of the leads I, II, aVL, V4-V6), and 3) normal T-waves (not meeting the criteria for negative or low amplitude T-waves). Subjects were followed for 10 years for the occurrence of SCD, cardiac death, or death from any cause. Results A total of 239 subjects (3.5%) had negative T-waves, 869 (12.7%) low amplitude T-waves, and 5746 (83.8%) normal T-waves. The Table shows the baseline characteristics. Subjects with T-wave abnormalities were older and had more often cardiovascular morbidities than subjects with normal T-waves. Cardiovascular morbidities were most common in subjects with negative T-waves. After adjusting for multiple clinical factors, negative T-waves (HR 3.91; 95% CI 2.30–6.64) and low amplitude T-waves (HR 1.80; 95% CI 1.13–2.86) were associated with SCD, when compared to normal T-waves. Furthermore, both negative T-waves and low amplitude T-waves associated with cardiac death (HR 2.34; 95% CI 1.75–3.13 and HR 1.49; 95% CI 1.17–1.91, respectively) and death from any cause (HR 1.85; 95% CI 1.50–2.27 and HR 1.45; 95% CI 1.24–1.70, respectively). The Figure displays the survival plots for SCD according to T-wave group. Conclusion In addition to negative T-waves, low amplitude T-waves also associate with SCD risk in the general population. Focus should be also placed on these minor T-wave abnormalities in the future. Kaplan-Meier plot Funding Acknowledgement Type of funding source: Foundation.
