Meta-Analysis of Racial Disparity in Clinical Outcome Among Congenital Heart Disease Patients Postsurgery.

Congenital heart disease (CHD), the most prevalent congenital disorder in newborns, is a leading cause of infant mortality. Mortality rates have declined over time with advancements in knowledge and management approaches. Despite these advancements, studies on racial disparities in CHD surgical mortality have yielded inconclusive results. We aim to evaluate the disparity among the clinical outcomes post-CHD surgery. A comprehensive literature search was conducted on PubMed, Embase, and Scopus utilizing predefined MeSH terms coupled with Boolean operators "AND" and "OR." The search strategy included the terms "congenital heart disease" AND "racial disparity" OR "minorities" OR "Black" OR "White" AND "mortality." Our meta-analysis sought observational studies published from inception until 10th March 2023 reporting post-surgical incidence of mortality in Black and White patients with CHD. We identified 5 studies, including 79616 patients with CHD. Of these, 15,124 Black patients and 64,492 White patients who underwent for CHD surgery. All included patients were less than 18 years of age with a definitive diagnosis of CHD. The mean length of the hospital stay was (11.5 vs 10.10) days, respectively. The pooled analysis showed that Black patients with CHD have significantly higher odds of postoperative mortality (OR, 1.46 (95%CI: 1.31-1.62), P < 0.001) with low heterogeneity across the studies. This very first meta-analysis shows that Black patients are at increased risk of mortality post-CHD surgery compared to White patients. These disparities need to be addressed, and proper guidelines need to be made with better medical infrastructure and treatment options for racial minority groups.

Virtual and augmented reality in cardiovascular care in low and middle income country.

The global health sector has witnessed an escalating integration of Virtual Reality (VR) and Augmented Reality (AR) technologies, particularly in high-income countries. The application of these cutting-edge technologies is gradually extending to Low- and Middle-Income Countries (LMICs), notably in the domain of cardiovascular care. AR and VR technologies are revolutionizing cardiovascular care by offering solutions for diagnosis, medical training, and surgical planning. AR and VR provide detailed and immersive visualizations of cardiac structures, aiding in diagnosis and intervention planning. In cardiovascular care, VR reduces patient-reported pain, eases anxiety, and accelerates post-procedural recovery. AR and VR are also valuable for life support training, creating immersive and controlled learning environments. AR and VR have the potential to significantly impact healthcare in low- and middle-income countries with enhanced accessibility and affordability. This review outlines the existing spectrum of VR and AR adoption and its burgeoning utility in the cardiovascular domain within LMICs.

Lateral medullary syndrome resulting from atrial fibrillation due to rheumatic heart disease: A case report and literature review.

Lateral medullary syndrome, resulting from cerebellar/brainstem infarction, can occur due to cardioembolic stroke from atrial fibrillation caused by rheumatic heart disease. This rare association highlights the importance of strict arrhythmia management, prophylactic anticoagulation, and timely diagnosis to prevent debilitating neurological outcomes.

Implantable cardioverter defibrillators for primary prevention in patients with ischemic and non-ischemic cardiomyopathy: A meta-analysis.

BACKGROUND: Ischemic and nonischemic cardiomyopathy (NICM) are one of the leading causes of sudden cardiac death (SCD). Evidence supporting Implantable Cardioverter Defibrillator (ICD) for the prevention of SCD and mortality has shown conflicting results to date. OBJECTIVE: We aim to evaluate the impact of ICD therapy with conventional care for the primary prevention of death of various causes in adults with ICM and NICM. METHODS: We performed a systematic literature search on the electronic database for relevant articles from inception until 30th May 2023. Pooled odds ratios (OR) were calculated using a random effect model, and a p-value of <0.05 was considered statistically significant. RESULTS: A total of 13 randomized controlled trials involving 7857 patients were included in the study. Pooled analysis showed that ICD therapy was associated with a significant reduction in the incidence of all-cause mortality (OR, 0.69 (95%CI:0.55-0.87), P = 0.001), with a similar trend among ICM and NICM compared with the control group. ICD therapy also reduces the incidence of SCD (OR, 0.32(95%CI: 0.24-0.43), P<0.00001) with a similar trend in ICM and NICM, as well as death due to arrhythmia (OR, 0.35(95%CI: 0.19-0.64), P<0.001). However, the incidence of cardiovascular mortality in the ICD group (OR, 0.77(95%CI: 0.58-1.02), P=0.07) was comparable to the control group. CONCLUSION: ICD therapy was associated with a reduction in the incidence of all-cause mortality, sudden cardiac death, and death due to arrhythmia among ischemic and nonischemic cardiomyopathy patients.

Association between baseline high-sensitive C-reactive protein, homocysteine levels, and post-stroke depression among stroke patients: a systematic review, meta-analysis, and meta-regression.

BACKGROUND: Post-stroke depression (PSD) is a prevalent neuropsychiatric sequelae following stroke, often associated with diminished functional recovery and heightened mortality risk. Emerging evidence suggests neuroinflammation, triggered in response to stroke events, may be instrumental in precipitating PSD. AIM: This study aims to assess the significance of high-sensitivity C-reactive protein (Hs-CRP) and homocysteine (Hcy) in post-stroke individuals with PSD. METHODS: We systematically searched all electronic databases from inception until May 30, 2023. Outcomes were reported as standard mean difference (SMD), and their corresponding 95% confidence interval (95% CI). RESULTS: A total of 12 studies with 3,230 patients were included in this study. The mean age of the overall cohort was 65.7 years, and patients with PSD were observed to be older than patients without PSD (68.3 years versus 63.1 years). We observed a higher female prevalence in the PSD group (44.4% versus 40.7%). PSD patients were more likely to be widowed (19.4% versus 8.4%) and more likely to have a family history of psychiatric disorder (11.3% versus 4.9%) compared to non-PSD patients. We also observed that patients with PSD had higher levels of baseline Hs-CRP [SMD 0.16, (95% CI 0.08 to 0.25), p<0.001], and Hcy [SMD 0.14, (95% CI 0.05 to 0.22), p<0.001] than patients without PSD. Meta-regression analysis did not reveal any effect modifier for higher Hs-CRP in the study group, however, history of widowhood was a significant effect modifier when assessing Hcy levels between the two groups (coefficient 1.998, p=0.038). CONCLUSION: Baseline levels of Hs-CRP and Hcy were significantly higher in patients with PSD, highlighting the role of recognizing demographic and biochemical markers in understanding the complexities of post-stroke depression.

Association Between Catheter Ablation and Dementia Among Patients With Atrial Fibrillation: A Systematic Review and Meta-analysis.

Atrial fibrillation (AF) is associated with an increased risk of Dementia. However, the association between catheter ablation (CA) in patients with atrial fibrillation and the risk of dementia is not well established, with conflicting results to date. We aimed to evaluate the association between CA patients and the risk of Dementia. We performed a systematic literature search using the PubMed, Embase, Scopus, and Cochrane libraries for relevant articles from inception until 10th May 2023. Hazard ratios (HR) were pooled using a random-effect model, and a P-value of < 0.05 was considered statistically significant. A total of 5 studies with 125,649 patients (30,192 in the CA group and 95,457 in the non-CA group) were included. The mean age of patients among CA and non-CA groups was comparable (58.7 vs 58.18). The most common comorbidity among CA and non-CA groups was hypertension (18.49% vs 81.51%), respectively. Pooled analysis of primary outcome showed that CA was associated with a significant reduction in the risk of Dementia (HR, 0.63 [95% CI: 0.52-0.77], P < 0.001). Similarly, pooled analysis of secondary outcomes showed that the patients with CA had a lower risk of Alzheimer's disease (HR, 0.78 [95% CI: 0.66-0.92], P < 0.001) compared with the non-CA group. However, there was no statistically significant difference in the risk of vascular dementia (HR, 0.63 [95% CI: 0.38-1.06], P = 0.08) between both groups of patients. Our study suggested that catheter ablation reduced the risk of dementia and Alzheimer's disease compared to the nonablation group of patients.

Cardioprotective effects of sodium glucose cotransporter 2 inhibitor versus dipeptidyl peptidase 4 inhibitor in type 2 diabetes: A meta-analysis of comparative safety and efficacy.

Background: Sodium glucose cotransporter 2 inhibitors are recommended for the treatment of heart failure due to their cardioprotective effects, despite primarily being used as antidiabetic medications. However, the comparative profile of two antidiabetic drugs, sodium glucose cotransporter 2 inhibitors with dipeptidyl peptidase 4 inhibitor remains unclear. Study hypothesis: This study aims to compare the safety and efficacy profiles of sodium glucose cotransporter 2 inhibitors versus dipeptidyl peptidase 4 inhibitor drugs. Methods: A comprehensive search was conducted in PubMed, Scopus, Web of Science, Google Scholar, and ClinicalTrials.gov using appropriate Medical Subject Headings terms from inception until February 23, 2023. The outcomes were pooled using a random-effects model for hazard ratio with a 95% confidence interval. A p-value of <0.05 was considered statistically significant. Results: Twelve studies were included after systematic screening, with a sample size of 745,688 for sodium glucose cotransporter 2 inhibitors and 769,386 for dipeptidyl peptidase 4 inhibitor. The mean age in each group was 61.1 (8.52) and 61.28 (9.25) years, respectively. Upon pooling the included articles with sodium glucose cotransporter 2 inhibitors versus dipeptidyl peptidase 4 inhibitor, the primary outcome of all-cause death demonstrated an hazard ratio of 0.64 (0.57, 0.70), I 2: 65.54%, p < 0.001, and major adverse cardiovascular events yielded an hazard ratio of 0.76 (0.65, 0.86), I 2: 87.83%, p < 0.001. The secondary outcomes included myocardial infarction with an hazard ratio of 0.84 (0.78, 0.90), I 2: 47.64%, p < 0.001, stroke with an hazard ratio of 0.81 (0.75, 0.87), I 2: 36.78%, p < 0.001, and hospitalization with an hazard ratio of 0.62 (0.53, 0.70), I 2: 83.32%, p < 0.001. Conclusion: Our findings suggest that compared to dipeptidyl peptidase 4 inhibitor, initiating treatment with sodium glucose cotransporter 2 inhibitors provides cardiovascular disease protection and may be considered in patients with type 2 diabetes.

Association between rheumatoid arthritis and atrial fibrillation: A systematic review and meta-analysis.

Rheumatoid arthritis (RA) is an autoimmune disorder with a varying range of organs involved leading to adverse outcomes. However, very little is known, with conflicting results about the association between RA and atrial fibrillation (AF). We aim to evaluate the association between RA and AF, and other clinical outcomes. We performed a systematic literature search using PubMed, Embase, and Scopus for relevant articles from inception until September 10, 2023. Primary clinical outcomes were AF. Secondary outcomes were acute coronary syndrome (ACS), stroke, and all-cause mortality (ACM). A total of 4 679 930 patients were included in the analysis, with 81 677 patients in the RA group and 4 493 993 patients in the nonrheumatoid arthritis (NRA) group. The mean age of the patients was 57.2 years. Pooled analysis of primary outcomes shows that RA groups of patients had a significantly higher risk of AF (odds ratios [OR], 1.53; 95% confidence interval [CI]: [1.16-2.03], p < .001) compared with NRA groups. Secondary Outcomes show that the RA group of patients had significantly higher odds of ACS (OR, 1.39; 95% CI: [1.26-1.52], p < .001), and ACM (OR, 1.19; 95% CI: [1.03-1.37], p = .02) compared with the NRA groups. However, the likelihood of stroke (OR, 1.02; 95% CI: [0.94-1.11], p = .61) was comparable between both groups of patients. Our study shows that RA groups of patients are at increased risk of having AF, ACS, and ACM.

Association between testosterone replacement therapy and cardiovascular outcomes: A meta-analysis of 30 randomized controlled trials.

BACKGROUND: The Cardiovascular safety of testosterone replacement therapy (TRT) among men with hypogonadism is not well established to date. Hence, we sought to evaluate the cardiovascular disease (CVD) outcomes among patients receiving testosterone therapy by using all recently published randomized controlled trials. METHODS: We performed a systematic literature search on PubMed, EMBASE, and Clinicaltrial.gov for relevant randomized controlled trials (RCTs) from inception until September 30th, 2023. RESULTS: A total of 30 randomized trials with 11,502 patients were included in the final analysis. The mean age was ranging from 61.61 to 61.82 years. Pooled analysis of primary and secondary outcomes showed that the incidence of any CVD events (OR, 1.12 (95%CI: 0.77-1.62), P = 0.55), stroke (OR, 1.01 (95%CI: 0.68-1.51), P = 0.94), myocardial infarction (OR, 1.05 (95%CI: 0.76-1.45), P = 0.77), all-cause mortality (OR, 0.94 (95%CI: 0.76-1.17), P = 0.57), and CVD mortality (OR, 0.87 (95%CI: 0.65-1.15), P = 0.31) was comparable between TRT and placebo groups. CONCLUSION: Our analysis indicates that for patients with hypogonadism, testosterone replacement therapy does not increase the CVD risk and all-cause mortality.

Extracorporeal Membrane Oxygenation-Impella (ECPELLA) in a Patient With Recalcitrant Ventricular Tachycardia Undergoing Ablation.

In advanced heart failure, refractory hemodynamically unstable ventricular tachycardia (VT) can be life-threatening. The utilization of short-term temporary mechanical circulatory support (MCS) has been described. Still, it is limited to the intra-aortic balloon pump (IABP) or Impella 2.5/CP (Abiomed Inc., Danvers, MA, USA) which may only provide up to 1-2.5 L/min of added support. Escalation of MCS therapies should be considered. Referrals to advanced tertiary heart transplant centers should be done early to afford patients the best chance at an optimal outcome, with the option for heart transplant evaluation if needed. We present a case of recalcitrant hemodynamically unstable VT complicated by cardiac arrest, eventually undergoing successful VT ablation while supported on veno-arterial extracorporeal membrane oxygenation (VA ECMO) and Impella 5.5 as a vent strategy in the extracorporeal membrane oxygenation-Impella (ECPELLA) configuration.

Single Nucleotide Polymorphisms in Cytokine Genes are Associated with the Susceptibility to Oral Squamous Cell Carcinoma.

Oral squamous cell carcinoma (OSCC) is the most common type of cancer among men in the Indian subcontinent. Cytokines regulate inflammation and angiogenesis in a variety of cancers. Genetic variability in the cytokine genes can potentially influence the predisposition to oral carcinogenesis. The aim of the current study was to investigate the associations of SNPs in cytokine genes with the susceptibility of oral squamous cell carcinoma. In the present study, we have analyzed the allelic frequency of 32 single nucleotide polymorphisms (SNPs) using MassArray-based iPLEX assay in 16 cytokine genes in 166 OSCC patients and 151 healthy subjects from central India. Out of 32 SNPs analyzed, five SNPs were significantly associated with the risk of OSCC. AA and GG genotypes of IL-1ß +3953 were associated with an increased and decreased risk of OSCC, respectively. In several genetic models, GG genotype and G allele in IL-12A 3'UTR G>A were found to be associated with an increased risk of OSCC. Similarly, the GG genotype of IL-12B +1188 T>G was associated with increased susceptibility to OSCC. We conclude that SNPs in the genes coding for IL-1ß, IL-12A and IL-12B are associated with increased genetic susceptibility to OSCC in the central Indian population.

Procedural safety of transcatheter aortic valve replacement with Portico valve: a systematic review.

BACKGROUND: The Portico transcatheter aortic heart valve is a self-expandable, fully resheathable bioprosthetic valve with a nitinol frame and porcine pericardial sealing cuff. It has been used among symptomatic severe aortic stenosis (AS) who are at high or extreme surgical risk. However, till date very few studies has been reported with inconclusive evidence for its postprocedure safety outcomes. OBJECTIVE: The authors aim to evaluate the safety of the Portico transcatheter aortic valve replacement system among patients with AS. METHODOLOGY: The authors conducted a systematic literature search on PubMed, Embase, and Scopus from inception till 10th April 2023 by using predefined MESH terms using 'AND' and 'OR'. The following search terms were used: 'Aortic Stenosis' AND 'Transcatheter aortic valve replacement' OR 'Portico valve'. Finally, descriptive statistics were used to summarize the data in this paper. The mean and SD were adopted to describe continuous variables, whereas frequencies and percentages were used for dichotomous data. RESULTS: A total of 7 studies with 2782 patients were included in the analysis. The mean age of patients was 82.3 years, and 54.63% were female. The most common comorbidity was hypertension (65.21%) and diabetes mellitus (26.45%). Among patients of AS with Portico valve implants, postprocedural outcomes including 30-day mortality (2.32%), cardiovascular mortality (2.37%), stroke (2.23%), myocardial infarction (0.94%), major bleeding (3.97%), major vascular complications (4.91%), acute kidney injury (1.37%), and permanent pacemaker implantations in 15.73% patients were reported. Overall, device success was observed in 95.82% of patients. CONCLUSION: Transcatheter aortic valve replacement with the repositionable Portico valve, a new bioprosthesis, appears to have a low postprocedural mortality rate and other clinical outcomes in high-risk patients with severe AS.

The Racial Disparity Among the Clinical Outcomes Post Stroke and its Intervention Outcomes: A Systematic Review and Meta-analysis.

The Racial disparity between the clinical outcomes poststroke have not been well studied, with limited literature available. We conducted a meta-analysis to evaluate the poststroke outcomes among the White and Black race of patients. We systematically searched all electronic databases from inception until March 1, 2023. The primary endpoint was post stroke in-hospital mortality, and all-cause mortality. Secondary endpoints were poststroke intervention in-hospital mortality, intracerebral hemorrhage, and all-cause mortality (ACM). A total of 1,250,397 patients were included in the analysis, with 1,018,892 (81.48%) patients of the White race and 231,505 (18.51%) patients in the Black race. The mean age of the patients in each group was (73.55 vs 66.28). The most common comorbidity among White and Black patients was HTN (73.92% vs 81.00%), and DM (29.37% vs 43.36%). The odds of in hospital mortality post stroke (OR, 1.45 [95% CI:1.35-1.55], P <0.001), and all-cause mortality (OR, 1.40 [95% CI:1.28-1.54], P < 0.001) were significantly higher among White patients compared with Black patients. Among patients with post stroke intervention the odds of in-hospital mortality (OR, 1.29 (95% CI: 1.05-1.59, P = 0.02), and intracerebral hemorrhage (ICH) (OR, 1.15, [95% CI:1.06-1.26], P < 0.01) were significantly higher among White patients compared with Black patients post intervention. However, all-cause mortality (OR,1.21 [95% CI: 0.87-1.68, P = 0.25] was comparable between both groups. Our study is the most comprehensive and first meta-analysis with the largest sample size thus far, highlighting that White patients are at increased risk of mortality and post intervention intracerebral hemorrhage compared with Black patients.

Cardioprotective effect of antiviral therapy among hepatitis C infected patients: A meta-analysis.

Background: Hepatitis C (HCV) infections have been shown to be associated a with higher risk of atherosclerotic cardiovascular disease (CVD). However, the use of antiviral therapy (AVT) and the risk of CVD has not been well established with limited literature. Objective: We sought to evaluate the association between AVT use post-HCV infection and cardiovascular outcomes. Methods: We performed a systematic literature search using PubMed, Embase, and Scopus for relevant articles from inception until 10th March 2023. Primary clinical outcomes were the incidence of any CVD. Secondary endpoints were all-cause of mortality, stroke, myocardial infarction, and peripheral artery disease. Results: A total of 394,452 patients were included in the analysis (111,076 in the AVT group and 283,376 patients in the NAVT group). The mean age of patients among AVT and NAVT groups was comparable (58.7 vs 58.18). The pooled analysis of primary outcomes showed that AVT was associated with a significantly reduced risk of any CVD (HR, 0.55(95%CI: 0.41-0.75), P < 0.001) compared with the NAVT group of patients. Secondary outcomes including ACM (HR, 0.38(95%CI: 0.32-0.46), P < 0.001), MI (HR, 0.62(95%CI: 0.41-0.94), P = 0.02), and PAD (HR, 0.62(95%CI: 0.41-0.93), P = 0.02) were significantly lower among AVT groups compared with NAVT groups of patients with HCV infection. However, the risk of stroke was comparable between both groups of patients (HR, 0.79(95%CI: 0.58-1.07), P = 0.13). Conclusion: Our analysis shows HCV-infected patients post-AVT have a significantly lower risk of any CVD, MI, ACM, and PAD compared with NAVT groups of patients.

Patterns of healthcare seeking behavior among persons with diabetes in Central India: A mixed method study.

BACKGROUND: Management of diabetes is complex and requires multiple lifestyle modifications, drug therapy, and a sustained regular follow-up. Complexities of health-seeking pattern in individuals with diabetes have been poorly characterized. OBJECTIVES: To understand the health-seeking patterns, and reasons of provider preference and switching among persons with diabetes. MATERIALS AND METHODS: We performed a mixed methods study in an urban slum setting of Bhopal. This urban slum was chosen as being a field practice area of the institute, a complete sampling frame with listing of households, and individuals with chronic disease conditions (including diabetes) was available. To be included in the study, the individual should have been an adult, aged ≥20 years, and diagnosed as type 2 diabetes mellitus. Descriptive statistical analysis of sociodemographic and disease management variables was performed. For qualitative component, interviews were transcribed and primary coding was done by two investigators followed by condensation of codes into themes or categories. The frequency of these content categories was presented with count and proportions. RESULTS: In total, 60 individuals with diabetes were interviewed. Of all individuals, 36 (60%) were asymptomatic at the time of the first diagnosis, and 57 (95%) were currently under treatment from some healthcare provider. About 25 (41.6%) switched their first provider and remaining continued with the same provider. Second provider was sought by 9 (36%) of 25 patients. Reasons for switching were perceived nonrelief, cost of care, distance of facility, and behavior of care provider. CONCLUSIONS: Healthcare provider switching is common among persons with diabetes which has implications on continuity of care.
