Background: Echocardiographic prognostic indicators of precapillary pulmonary hypertension (PH) mortality has been inconclusive. This study aims to examine the prognostic values of right ventricular echocardiographic functional parameters in predicting precapillary PH mortality.

Methods: Systematic searches were conducted in the ScienceDirect, Medline, and Cochrane databases for longitudinal studies. Assessments included means and hazard ratios (HRs) for Tricuspid Annular Plane Systolic Excursion (TAPSE), Right Ventricular Systolic Pressure (RVSP), Right Ventricular Longitudinal Strain (RVLS), Right Ventricular Fractional Area Change (RVFAC), Right Ventricular Ejection Fraction (RVEF), and Right Ventricular Index of Myocardial Performance (RIMP).

Results: The meta-analysis included 24 cohort studies comprising 2171 participants. Mean values were as follows: TAPSE 17.62 mm, RVSP 77.50 mmHg, RVLS - 16.78%, RVFAC 29.81%, RVEF 37.56%, and RIMP 0.52. TAPSE (HR: 1.28; 95% CI 1.17-1.40; p < 0.001), RVLS (HR: 1.74; 95% CI 1.34-2.26; p < 0.001), RVFAC (HR: 1.40; 95% CI 1.13-1.75; p < 0.001), RVEF (HR: 1.08; 95% CI 1.02-1.15; p = 0.01), and RIMP (HR: 1.51; 95% CI 1.23-1.86; p < 0.001) emerged as significant prognosticators of precapillary PH mortality, with the exception of RVSP (HR: 1.04; 95% CI 0.99-1.09; p = 0.14). TAPSE summary receiver operating characteristics (sROC) analysis yielded an area under the curve (AUC) of 0.85 [95% CI 0.81-0.88] with a sensitivity of 0.81 [95% CI 0.63-0.91] and a specificity of 0.74 [95% CI 0.54-0.87]. RVLS sROC resulted in an AUC of 0.74 [95% CI 0.70-0.78] with a sensitivity of 0.74 [95% CI 0.57-0.86] and a specificity of 0.69 [95% CI 0.64-0.75].

Conclusions: TAPSE, RVLS, RVFAC, RVEF, and RIMP demonstrated promise as valuable prognostic indicators for precapillary PH mortality.

Background: A new challenge in coronary artery disease treatment has emerged, where specific populations exhibit ischemic symptoms without any obstruction in the epicardial coronary artery. Instead, they exhibit slow coronary contrast flow, referred to as coronary slow flow (CSF). This study aims to identify several predictors of CSF.

Results: This case-control study was conducted at the Regional General Hospital of West Nusa Tenggara Province in Indonesia from December 2016 to February 2024. The study involved sixty subjects, with 30 in each group of CSF and normal epicardial coronary artery angiogram (NECA). CSF is enforced by the TIMI frame count (TFC) greater than 27 frames. Among all the predictors studied, coronary artery diameter (p < 0.001) and random blood sugar (p = 0.049) were found to affect the CSF significantly. In the multivariate analysis, coronary artery diameter remained a significant predictor (adjusted OR 10.08, 95% CI 2.64-38.50, p < 0.001), with an optimal cut-off point of more than 3.56 mm, a sensitivity of 76.7%, and a specificity of 70.7% (AUC = 0.787, p < 0.001).

Conclusion: The coronary artery diameter strongly predicts CSF in patients undergoing coronary angiography.

Background: Rheumatic heart disease (RHD) continues to pose a significant burden on global health, particularly in socioeconomically disadvantaged populations. We present the case of a 38-year-old woman with severe multivalvular RHD and giant atria, highlighting the challenges and complexities of managing this condition.

Case presentation: The patient presented with progressively worsening dyspnoea, signs of right heart failure, and severe valvular abnormalities. Diagnostic evaluations revealed severe mixed mitral valve disease in the form of mitral stenosis and regurgitation, along with involvement of the aortic and tricuspid valves, leading to significant enlargement of both atria. Despite facing socioeconomic constraints and poor adherence to treatment, the patient underwent successful surgical intervention, resulting in remarkable symptomatic improvement.

Conclusions: Through this case, we emphasise the importance of early detection, comprehensive management strategies, and multidisciplinary care in addressing the complexities of RHD. Despite the challenges posed by socioeconomic disparities, positive outcomes can be achieved with timely diagnosis and appropriate intervention. This case underscores the need for targeted efforts to improve access to healthcare resources and reduce the global burden of RHD.

Background: Atrial fibrillation (AF) poses a significant stroke risk in heart disease patients. This systematic review aims to evaluate the efficacy and safety of non-vitamin K oral antagonists (NOACs) versus vitamin K antagonists (VKAs) in AF patients with and without any valvular heart disease (VHD/N-VHD).

Methods: A systematic search was conducted on PubMed, Scopus, and Google Scholar up to March 3, 2022. Efficacy and safety parameters were analyzed.

Results: A total of 85,423 subjects from 10 studies were included in this meta-analysis. NOACs and VKAs showed similar effects on ischemic stroke in AF patients with VHD/N-VHD (RR 0.97; 95% CI 0.72-1.30; p = 0.83) and also on systemic embolic events (RR 1.02; 95% CI 0.83-1.25; p = 0.86). Similar effects were seen in VHD and N-VHD subgroups. Both treatments had similar effects on myocardial infarction in AF patients with VHD/N-VHD (RR 0.79; 95% CI 0.49-1.26; p = 0.32), VHD (RR 0.78; 95% CI 0.59-1.02; p = 0.07), and N-VHD subgroups (RR 0.82; 95% CI 0.30-2.21; p = 0.69). NOACs reduced the risk of intracranial bleeding in AF VHD/N-VHD (RR 0.64; 95% CI 0.54-0.77; p < 0.0001), VHD (RR 0.59; 95% CI 0.42-0.82; p = 0.002), and N-VHD subgroups (RR 0.70; 95% CI 0.57-0.85; p = 0.0003). Additionally, NOACs reduced the risk of gastrointestinal bleeding in AF VHD/N-VHD (RR 0.80; 95% CI 0.66-0.96; p = 0.02), specifically in the VHD subgroup (RR 0.69; 95% CI 0.54-0.89; p = 0.004). Moreover, NOACs were associated with a decreased risk for minor and non-fatal bleeding in AF patients with VHD/N-VHD (RR 0.86; 95% CI 0.75-0.99; p = 0.04).

Conclusion: NOACs are effective and safe for ischemic stroke, systemic embolic events, myocardial infarction, intracranial bleeding, and gastrointestinal bleeding in AF patients with VHD/N-VHD.

Background: Pulmonary embolism (PE) is an important cause of mortality and morbidity in the geriatric population. We aimed to compare the ability of the pulmonary embolism severity index (PESI), rapid emergency medicine score (REMS), and hypotension, oxygen saturation, low temperature, electrocardiogram change, and loss of independence (HOTEL) to predict prognosis and intensive care requirement in geriatric patient with PE.

Results: The median age of 132 patients was 77 (71-82) years. PESI was higher in the non-survivor group [132 (113-172)] (P =0.001). The median REMS was 8 (7-10), and it was higher in the non-survivor group [10 (7.5-12.0)] (p = 0.005). The median HOTEL score was 1 (0-2) in the whole cohort and 2 (1-3) in the non-survivor group, indicating significant difference compared to the survivor group (P = 0.001). The area under the curve (AUC) values of HOTEL, REMS, and PESI were determined as 0.72, 0.65, and 0.71, respectively. For the prediction of intensive care requirement, the AUC values of HOTEL, REMS, and PESI were 0.76, 0.75, and 0.76, respectively, with no significant difference in pairwise comparisons (PESI vs. REMS: p = 0.520, HOTEL vs. PESI: P = 0.526, REMS vs. HOTEL: P = 0.669, overall test: P = 0.96, DeLong's test). The risk ratios of HOTEL and PESI were parallel to each other [5.31 (95% confidence interval (CI): 2.53-11.13) and 5.34 (95% CI: 2.36-12.08), respectively].

Conclusion: HOTEL and REMS were as successful as PESI in predicting short-term mortality and intensive care requirement in geriatric patients with PE. These scores are also more practical since they have fewer parameters than PESI.

Background: Takayasu arteritis (TA) is a chronic inflammatory disease of unknown etiology characterized by a large vessel vasculitis involving the aorta and its branches. Myocardial involvement is extremely unusual in TA and is mostly in the form of myocarditis, ventricular hypertrophy, and ventricular dysfunction secondary to coronary ischemia. Submitral aneurysms have been reported in TA and has been attributed to the chronic inflammatory process in TA.

Case presentation: We report a novel instance of left ventricular apical aneurysm in a 37-year-old lady with TA and normal epicardial coronaries. She was diagnosed with a left ventricular apical aneurysm, moderate aortic regurgitation, and moderate pericardial effusion. The coronary arteries were normal. The patient had concomitant chronic active Epstein-Barr virus infection complicating patient outcome.

Conclusions: Left ventricular apical aneurysm with normal epicardial coronaries is a rare cause of heart failure in Takayasu arteritis. Concomitant chronic active Epstein-Barr virus infection can potentially accentuate the inflammatory process in Takayasu arteritis and complicate management and patient outcomes.

Background: Cardiogenic shock (CS) remains a major cause of in-hospital mortality in the setting of acute myocardial infarction (AMI). However, little evidence is available regarding the optimal order of intra-aortic balloon counter-pulsation (IABP) insertion and primary percutaneous coronary intervention (PPCI). The aim of this study was to assess the hospital and short-term survival benefits of two different IABP insertion approaches, before versus after PPCI in patients with acute myocardial infarction and cardiogenic shock.

Results: Total mortality was 80 patients representing 48.4% of the total 165 studied patients; 60 patients died during the hospital admission period, while the remaining 20 patients died post-discharge. In-hospital mortality was significantly higher in Post-PPCI-IABP group 40 (49.4%) versus Pre-PPCI-IABP group 20 (23.8%) (P = 0.001). Moreover, the mortality difference between the two groups was sustained over six-month follow-up period, where 15 patients (18.5%) died in the Post-PPCI-IABP group, while only 5 patients 6.0% died in the Pre-PPCI-IABP (P = 0.001).

Conclusions: Early IABP insertion before PPCI is associated with improved in-hospital and long-term survival when used for patients presenting with AMI complicated by hemodynamic instability.

Background: Heart failure (HF) poses a major health problem, where frequent HF rehospitalizations (HFH) heavily burden national health systems. HFH are predominantly linked to inadequate decongestion before discharge. It is uncertain if systematic implementation of cardio-pulmonary ultra-sound imaging (CPUSI) to standard HF management can improve outcomes and reduce HFH.

Results: This study recruited 50 patients admitted with acute decompensated heart failure (ADHF). Besides the conventional daily assessment, CPUSI was systematically performed to guide treatment decisions, focusing on ventricular filling pressure and 8-zone lung ultrasound (LUS) score. On-admission and predischarge LUS scores were correlated to clinical outcomes. The mean age of the study group was 55.7 ± 10.59 years, with predominance of male gender. Supplementing clinical judgment, CPUSI modified therapeutic strategy in 57 out of 241 assessments (24%), improving patients' care. Besides its value in guiding therapeutic decisions, the LUS score on admission had a significant positive correlation to the length of ICU stay and the total hospitalization length. Also, LUS score > 12 at discharge predicted 90-day HFH with sensitivity and specificity of 100% and 98%, respectively.

Conclusions: Systematic CPUSI can improve HF management by complementing the often challenging judgment of pulmonary congestion. Adding periodic evaluation of ventricular filling pressures and LUS scores to clinical assessment can optimize treatment decisions and improve patient care. LUS score was a significant predictor for in-hospital and post-discharge clinical outcomes.

Background: Evaluation of the patients with MINOCA and identifying the underlying aetiology remains challenging. However, investigation in most patients remains limited to coronary angiography (CAG). The study aimed to assess the clinical profile, investigations and cardiac imaging of the patients with MINOCA and its outcomes.

Results: Out of 55 patients with MINOCA, CAG was normal in 16 (29.1%), while 39 (69.9%) had nonobstructive coronary artery disease. Of 55 patients, 34 had limited workup (Group 1) and only 21 had advanced workup (Group 2). In comparison to Group 1, Group 2 had a significantly higher association with the identification of possible underlying aetiology (16 vs. 4, p < 0.001) and a change in the management (10 vs. 3, p = 0.002).

Conclusion: Diagnostic workup in patients with MINOCA was limited to CAG in 61.8% of patients in this study. However, patients with advanced workup had a significantly higher association with the change in the treatment and identifying possible underlying aetiology in such patients.

Background: Functional health status is increasingly being recognized as a viable endpoint in heart failure (HF) trials. We sought to assess its prognostic impact and relationship with traditional clinical outcomes in patients with HF.

Methods: MEDLINE and Cochrane central were searched up to January 2021 for post hoc analyses of trials or observational studies that assessed independent association between baseline health/functional status, and mortality and hospitalization in patients with HF across the range of left ventricular ejection fractions to evaluate the prognostic ability of NYHA class [II, III, IV], KCCQ, MLHFQ, and 6MWD. Hazard ratios (HR) with 95% confidence intervals were pooled.

Results: Twenty-two studies were included. Relative to NYHA I, NYHA class II (HR 1.54 [1.16-2.04]; p < 0.01), NYHA class III (HR 2.08 [1.57-2.77]; p < 0.01), and NYHA class IV (HR 2.53 [1.25-5.12]; p = 0.01) were independently associated with increased risk of mortality. 6MWD (per 10 m) was associated with decreased mortality (HR 0.98 [0.98-0.99]; p < 0.01). A 5-point increase in KCCQ-OSS (HR 0.94 [0.91-0.96]; p < 0.01) was associated with decreased mortality. A high MLHFQ score (> 45) was significantly associated with increased mortality (HR 1.30 [1.14-1.47]; p < 0.01). NHYA class, 6MWD (per 10 m), KCCQ-OSS, and MLHFQ all significantly associated with all-cause mortality in patients with HF.

Conclusion: Identifying such patients with poor health status using functional health assessment can offer a complementary assessment of disease burden and trajectory which carries a strong prognostic value.
