The roles of C-reactive protein-albumin ratio as a novel prognostic biomarker in heart failure patients: A systematic review.

C-Reactive Protein (CRP)-albumin ratio (CAR) is a novel prognostic biomarker that is predicted to be a more reliable indicator than CRP or albumin alone. Therefore, this systematic review aimed to evaluate the role of CAR in predicting poor outcomes of heart failure (HF) patients. We conducted a literature search across ProQuest, PubMed, ScienceDirect, Web of Science, and Scopus. All related studies assessing CAR and reporting mortality outcomes or other adverse outcomes were assessed. A total of five studies with a total of 1821 patients were included in this review. CAR is significantly associated with all-causes in-hospital mortality and out-hospital mortality in patients with acute and chronic heart failure. CAR is associated with higher hospitalization rates, the number of hospitalizations, severe New York Heart Association (NYHA) classification, and the risk of advanced HF. In conclusion, CAR is significantly associated with poor HF outcomes including all-cause mortality (cardiac and non-cardiac death).

Association polymorphism of guanine nucleotide-binding protein ß3 subunit (GNB3) C825T and insertion/deletion of the angiotensin-converting enzyme (ACE) gene with peripartum cardiomyopathy.

Introduction: Peripartum cardiomyopathy (PPCM) is a potentially life-threatening pregnancy-related heart disease. Genetic roles such as gene polymorphisms may relate to the etiology of PPCM. This study analyzes the association between single nucleotide gene polymorphism (SNP) guanine nucleotide-binding protein beta-3 subunit (GNB3) C825T and insertion/deletion (I/D) of the angiotensin-converting enzyme (ACE) gene with the incidence of PPCM. Methods: An analytic observational study with a case-control design was conducted at the Integrated Cardiac Service Center of Dr. Soetomo General Hospital, Surabaya, Indonesia. PPCM patients of the case and control groups were enrolled. Baseline characteristic data were collected and blood samples were analyzed for SNP in the GNB3 C825T gene and for I/D in the ACE gene by using the polymerase chain reaction, restriction fragment length polymorphism, and Sanger sequencing. We also assessed ACE levels among different ACE genotypes using a sandwich-ELISA test. Results: A total of 100 patients were included in this study, with 34 PPCM cases and 66 controls. There were significant differences in GNB3 TT and TC genotypes in the case group compared with that in the control group (TT: 35.3% vs. 10.6%, p = 0.003; TC: 41.2% vs. 62.5%, p = 0.022). The TT genotype increased the risk of PPCM by 4.6-fold. There was also a significant difference in the ACE DD genotype in the case group compared with that in the control group (26.5% vs. 9.1%, p = 0.021). DD genotypes increased the risk of PPCM by 3.6-fold. ACE levels were significantly higher in the DD genotype group than in the ID and II genotype groups (4,356.88 ± 232.44 pg/mL vs. 3,980.91 ± 77.79 pg/mL vs. 3,679.94 ± 325.77 pg/mL, p < 0.001). Conclusion: The TT genotype of GNB3 and the DD genotype of the ACE are likely to increase the risk of PPCM. Therefore, these polymorphisms may be predisposing risk factors for PPCM incidence. ACE levels were significantly higher in the DD genotype group, which certainly had clinical implications for the management of PPCM patients in the administration of ACE inhibitors as one of the therapy options.

Right ventricular dysfunction and pulmonary hypertension in COVID-19: a meta-analysis of prevalence and its association with clinical outcome.

Introduction: Rapid spread of COVID-19 has caused detrimental effects globally. Involvement of the ACE2 receptor has identified COVID-19 as a multi-organ disease. Preliminary studies have provided evidence that cardiac involvement, including right ventricular dysfunction (RVD) and pulmonary hypertension (PH), were found in COVID-19 cases, even in the non-advanced stage. This meta-analysis aims to analyze the prevalence of RVD and PH, and their association with COVID-19 clinical outcome. Material and methods: A systematic data search was conducted through PubMed, medRxiv, ProQuest, Science Direct, and Scopus databases using constructed keywords based on MeSH terms. Any outcomes regarding mortality, severity, ICU admission, and mechanical ventilation usage were analyzed using RevMan v.5.4 and Stata v.16. Results: A total of 16 eligible studies (1,728 patients) were included. Pooled prevalence of RVD in COVID-19 was 19% (95% CI: 13-25%), and PH was 22% (95% CI: 14-31%). RVD was associated with increased mortality (OR = 2.98 (95% CI: 1.50-5.89), p = 0.002), severity (OR = 3.61 (95% CI: 2.05-6.35), p < 0.001), ICU admission (OR = 1.70 (95% CI: 1.12-2.56), p = 0.01), and mechanical ventilation (MV) usage (OR = 1.60 (95% CI: 1.14-2.25), p = 0.007). PH was also associated with increased mortality (OR = 5.42 (95% CI: 2.66-11.060, p < 0.001), severity (OR = 5.74 (95% CI: 2.28-14.49), p < 0.001), and ICU admission (OR = 12.83 (95% CI: 3.55-46.41), p < 0.001). Conclusions: RVD and PH were prevalent in COVID-19 and associated with mortality, severity, ICU admission, and MV usage in COVID-19 patients. Bedside echocardiography examination could be considered as a novel risk stratification tool in COVID-19.

Low molecular weight heparin is associated with better outcomes than unfractionated heparin for thromboprophylaxis in hospitalized COVID-19 patients: a meta-analysis.

AIMS: This study aimed to compare the outcomes of the administration of LMWH and UFH in hospitalized COVID-19 patients. METHODS AND RESULTS: We systematically searched several databases and included observational studies or clinical trials that compared the outcomes of the administration of LMWH and UFH in hospitalized COVID-19 patients. A total of nine studies comprising 9637 patients were included. Metanalysis showed that LMWH administration was associated with a lower in-hospital mortality and 28/30-day mortality compared with UFH administration {[relative risk (RR) 0.44; 95% confidence interval (95% CI) 0.32-0.61; I2: 87.9%] and (RR 0.45; 95% CI 0.24-0.86; I2: 78.4%), respectively}. Patient with LMWH had shorter duration of hospital and ICU length of stay compared with UFH {[weighted mean difference (WMD) -2.20; 95% CI -3.01 to -1.40; I2:0%] and (WMD -1.41; 95% CI -2.20 to -0.63; I2: 0%), respectively}. The risk of ICU admission or mechanical ventilation was lower in patients who received LMWH than in those who received UFH (RR 0.67; 95% CI 0.55-0.81; I2: 67.3%). However, there was no difference in the incidence of bleeding with LMWH compared with UFH (RR 0.27; 95% CI 0.07-1.01; I2: 64.6%). CONCLUSION: Our meta-analysis showed that administration of LMWH was associated with better outcomes compared with UFH in hospitalized COVID-19 patients. Prospective cohorts and RCTs are urgently needed to explore the definitive effect of LMWH to provide direct high-certainty evidence. PROSPERO registration number: CRD42021271977.

Tamponade with recurrent chylopericardium in patient with non-Hodgkin's lymphoma: chemotherapy is the key management after pericardiocentesis.

Cardiac tamponade, the accumulation of fluid in the pericardial space, leads to impaired venous return, loss of left ventricular preload and haemodynamic collapse. Chylopericardium is an unusual cause of the pericardial effusion. This is often secondary to malignancy. Non-Hodgkin's Lymphoma is a primary malignancy from the lymph node. It can be produced by B lymphocytes, T lymphocytes or natural killer cells. The term chylopericardium refers to a pericardial effusion containing milky fluid within the intrapericardial space. We present a case of a 42-year-old male patient who came with dyspnoea as a result of cardiac tamponade caused by a massive milky pericardial effusion (chylopericardium) secondary to mediastinal non-Hodgkin's lymphoma.

Association of calcium channel blocker use with clinical outcome of COVID-19: A meta-analysis.

AIMS: This meta-analysis aims to analyze the association of calcium channel blocker (CCB) use with COVID-19 clinical outcomes. METHODS: PubMed, ProQuest, Science Direct, Scopus, and medRxiv databases were searched systematically in a limited period. The primary outcome was mortality. RESULTS: A total of 119,298 patients from 31 eligible studies were included. Pooled analysis of the random-effect model revealed CCB was not associated with reduced mortality (OR = 1.21 [95%CI: 0.98-1.49], p = 0.08). Interestingly, subgroup analysis in hypertensive patients revealed significantly reduced mortality (OR = 0.69 [95%CI: 0.52-0.91], p = 0.009). CONCLUSION: CCB usage was not associated with the outcome of COVID-19. However, CCB was associated with a decreased mortality rate in hypertensive COVID-19 patients.

Relationship of D-dimer with severity and mortality in SARS-CoV-2 patients : A meta-analysis.

INTRODUCTION: The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic. Many studies have shown that several laboratory parameters are related to disease severity and mortality in SARS-CoV-2 cases. This meta-analysis aimed to determine the relationship of a prognostic factor, D-dimer, with disease severity, need for intensive care unit (ICU) care, and mortality in SARS-CoV-2 patients. METHODS: A systematic search for all observational studies and trials involving adult patients with SARS-CoV-2 that had any data related to D-dimer on admission was conducted using PubMed, Science Direct, Scopus, ProQuest, and MedRxiv databases. We performed random-effects inverse-variance weighting analysis using mean difference (MD) of D-dimer values for outcomes such as disease severity, mortality, and need for ICU care. RESULTS: A total of 29 studies (4,328 patients) were included in this meta-analysis, which revealed a higher mean of D-dimer levels on admission in severe patients than in nonsevere patients (MD = 0.95, [95% confidence interval (CI): 0.61-1.28], P < .05; I2  = 90%). The nonsurvivor group had a higher pooled MD of D-dimer values on admission (MD = 5.54 [95% CI: 3.40-7.67], P < .05; I2  = 90%). Patients who needed ICU admission had insignificantly higher D-dimer values than patients who did not need ICU admission (MD = 0.29, [95% CI: -0.05 to 0.63], P = .10; I2  = 71%). CONCLUSION: Elevated D-dimer levels on admission were associated with an increased risk of disease severity and mortality in patients with SARS-CoV-2 infection.

Elevated fibrinogen and fibrin degradation product are associated with poor outcome in COVID-19 patients: A meta-analysis.

INTRODUCTION: COVID-19 is a systemic infection with a significant impact on coagulation which manifests in thromboembolism. There is an unknown relationship of which coagulation profile parameter at presentation has an association with poor outcome in COVID-19. OBJECTIVE: This meta-analysis aimed to determine the relationship between fibrinogen and FDP with poor outcome in COVID-19 patients. METHODS: A systematic search of all observational studies or trials involving adult patients with COVID-19 that had any data fibrinogen or FDP on admission was carried out using the PubMed, Science Direct, Scopus, ProQuest, and MedRxiv databases. We assessed the methodological quality assessment using the NIH Quality Assessment Tool. We performed random-effects inverse-variance weighting analysis using mean difference (MD). RESULTS: A total of 17 studies (1,654 patients) were included in this meta-analysis. It revealed a higher mean of fibrinogen levels on admission in patients with severe case compared to those with non-severe case (MD = 0.69, [95% CI: 0.44 to 0.94], p < 0.05; I2 = 72%, p < 0.05). Non-survivor group had a pooled higher mean difference of fibrinogen values on admission (MD = 0.48 [95% CI: 0.13 to 0.83], p < 0.05; I2 = 38%, p = 0.18). Higher FDP on admission was found in poor outcome (composite of severity, critically ill, and mortality) compared to good outcome (4 studies, MD = 4.84 [95% CI: 0.75 to 8.93], p < 0.05; I2 = 86%, p < 0.05). CONCLUSION: Elevated fibrinogen and FDP level on admission were associated with an increase risk of poor outcome in COVID-19 patients.

Coronary Angiography Characteristics as Predictor of Successful Chronic Total Occlusion Recanalization.

Although remarkable progress in percutaneous coronary intervention (PCI) has been achieved over the last decade, the success rate of chronic total occlusion (CTO) recanalization varies greatly. Coronary angiography characteristics may affect the success rate of CTO recanalization. This study sought to establish a scoring model to predict successful CTO recanalization based on coronary angiography characteristics. We analyze 287 angiography data from patients who underwent elective PCI. Angiography characteristics being measured were lesion location, blunt stump, calcification, ostial lesion, bridging collateral, bending, side branch, tortuosity, previous stent attempt, and lesion length of >20 mm. Data were analyzed using SPSS 25.0. Multivariate analysis shows that side branch lesion ( p = 0.000), proximal vessels tortuosity ( p = 0.015), calcified lesion ( p = 0.000), lesion length of >20 mm ( p = 0.000), and blunt stump ( p = 0.000) can predict the successful PCI in the CTO. ROC curve analysis of the score ability to predict successful PCI in the CTO showed area under curve of 0.89 (confidence interval 95%), the cutoff point of ≤2 with a sensitivity of 93.33%, and specificity of 88.23%. We concluded that the five angiography characteristics that strongly associate with successful PCI in the CTO are calcified lesion, blunt stump, lesion length >20 mm, proximal vessel tortuosity, and side branch lesion. This score may help cardiologists to predict the success probability of PCI in the CTO.

SCN5A gene mutations and the risk of ventricular fibrillation and syncope in Brugada syndrome patients: A meta-analysis.

Mutations in the gene encoding the main cardiac sodium channel (SCN5A) are the commonest genetic cause of Brugada syndrome (BrS). However, the effect of SCN5A mutations on the outcomes of ventricular fibrillation (VF) and syncope remains uncertain. To clarify this relationship, a meta-analysis was performed. A comprehensive search was conducted to identify all eligible studies from PubMed, MEDLINE, EBSCO, ProQuest, Science Direct, Clinical Key, and Cochrane database for cohort studies of BrS populations that had been systematically tested for SCN5A mutations. We did meta-analysis to see the relationship between SCN5A mutations and the occurrence of VF and/or syncope using RevMan 5.3. Five clinical studies met our criteria and included a total of 665 BrS patients. These studies included 45 patients with VF and 178 patients with syncope. We found that in BrS patients with SCN5A mutations the rate of VF event was 30.7% while in patients without mutations was 28.5% (Risk Ratio [RR] = 1.11, [95% CI: 0.61, 2.00], P = 0.73, I 2 = 0%). The occurrence of syncope events was 35.9% in patients with SCN5A mutations and 34.5% in patients without mutations (RR = 1.12, [95% CI: 0.87, 1.45], P = 0.37, I 2 = 39%). Furthermore, the occurrence of combined VF and syncope events were similar between the 2 groups (RR = 1.12, [95% CI: 0.89, 1.42], P = 0.34, I 2 = 11%). BrS patients with SCN5A mutations exhibit a similar risk of future occurence of VF and/or syncope as compared to those without SCN5A mutations.

Associations between four types of single-nucleotide polymorphisms in PLA2G7 gene and clinical atherosclerosis: a meta-analysis.

BACKGROUND: Previous studies suggested that some types of single nucleotide polymorphisms (SNPs) in PLA2G7 genes, encoding Lp-PLA2 have been reported to yield an antiatherogenic effect, but other studies mentioned otherwise. Thus, a comprehensive study to explore the effect of SNPs in PLA2G7 genes (V279F, A379V, R92H, I198T) toward clinical atherosclerosis is needed. METHODS: We searched eligible studies from PubMed, EBSCO, ProQuest, Science Direct, Springer, and Cochrane databases for case-control studies to assess the between four types of SNPs in PLA2G7 gene with risk of clinical atherosclerosis (CVD = cardiovascular disease, CAD = coronary artery disease, PAD = peripheral artery disease, ischemic stroke). All studies were assessed under Hardy-Weinberg Equilibrium, an additive model. This meta-analysis was performed by RevMan 5.3 to provide pooled estimate for odds ratio (ORs) with 95% confidence intervals (95% CIs). RESULTS: Fourteen clinical studies met our inclusion criteria. Those included 12,432 patients with clinical atherosclerosis and 10,171 were controls. We found that ORs of two variants SNPs (V279F, R92H) were associated with clinical atherosclerosis {V279F, OR = 0.88 (95% CI, 0.81-0.95); p = 0.0007, I2 = 40%}, {R92H, OR = 1.29 (95% CI, 1.09-1.53); p = 0.003, I2 = 73%}. Meanwhile, there was no significant associations between the other two, A379V {OR = 1.08 (95% CI, 0.93-1.26); p = 0.31, I2 = 78%} and I198T {OR = 1.12 (95% CI = 0.79-1.59); p = 0.53, I2 = 81%}. CONCLUSIONS: These results suggested that V279F polymorphism in PLA2G7 gene has a protective effect for clinical atherosclerosis, whereas R92H polymorphism might contribute toward increased risk of clinical atherosclerosis.
