Demographics and mortality trends of valvular heart disease in older adults in the United States: Insights from CDC-wonder database 1999-2019.

Background: Valvular heart disease (VHD) represents a spectrum of cardiac conditions, including valvular stenosis, valvular regurgitation, or mixed lesions affecting single or multiple valves. The severity of VHD has emerged as a major cause of cardiovascular (CV) morbidity and mortality among the older population in the United States (U.S). Objective: To evaluate temporal trends in mortality associated with VHD in the elderly U.S population between 1999 and 2019. Methods: We utilized the CDC WONDER database for VHD mortality in adults ≥75 from 1999 to 2019, using ICD-10 codes. Age-adjusted mortality rates (AAMR) per 100,000 people with associated annual percentage change (APC) were calculated. Joinpoint regression was used to assess the overall trends and trends for demographic, geographic, and type of valvular disease subgroups. Results: A total of 666,765 VHD deaths in older adults from 1999 to 2019 was identified, with an initial decline in AAMR until 2007 with an APC: 0.62, 95 % CI (-1.66-0.33), stability until 2014, and a significant decrease until 2019 (APC: 1.47, 95 % CI [-2.24-1.04], P < 0.0001). Men consistently had higher AAMRs compared to women (overall AAMR men: 173.6; women: 138.2). The AAMRs were found to be highest in the White (166.5), followed by American Indian or Alaska Native population at (93.8) Hispanic or Latino at (80.7), Black or African American populations at (74.1) and lastly Asian or Pacific Islander (73.4). Non-metropolitan areas manifested higher AAMRs for deaths related to VHD than metropolitan areas (overall AAMRs 160.5 vs 149.5) respectively. State-wide AAMRs varied, with the highest in Vermont at 324.2 (95 % CI [313.0-335.4], P < 0.0001) and the lowest in Mississippi at 88.0 (95 % CI [85.0-91.0], P < 0.0001). Non-rheumatic and aortic valve disorders in adults ≥75 years had higher mortality rates compared to rheumatic or mitral valve conditions in those <75 years. Conclusion: Our study showed a decline in U.S. VHD mortality from 1999 to 2019 but found persistent disparities by gender, race, age, region, and VHD type. Targeted policies for prevention and early diagnosis are needed to address these inequalities.

Temporal Trends in the Outcomes of Percutaneous Coronary Intervention With Zotarolimus Eluting Stents Versus Everolimus Eluting Stents: A Meta-Analysis of Randomized Controlled Trials.

INTRODUCTION: Long-term follow-up results of various trials comparing Zotarolimus eluting stents (ZES) with Everolimus eluting stents (EES) have been published recently. Additionally, over the last decade, there have been new trials comparing the ZES with various commercially available EES. We aim to conduct an updated meta-analysis in light of new evidence from randomized controlled trials (RCTs) to provide comprehensive evidence regarding the temporal trends in the clinical outcomes. METHODS: A comprehensive literature search was conducted across PubMed, Cochrane, and Embase. RCTs comparing ZES with EES for short (<2 years), intermediate (2-3 years), and long-term follow-ups (3-5 years) were included. Relative risk was used to pool the dichotomous outcomes using the random effects model employing the inverse variance method. All statistical analysis was conducted using Revman 5.4. RESULTS: A total of 18 studies reporting data at different follow-ups for nine trials (n = 14319) were included. At short-term follow-up (<2 years), there were no significant differences between the two types of stents (all-cause death, cardiac death, Major adverse cardiovascular events (MACE), target vessel myocardial infarction, definite or probable stent thrombosis or safety outcomes (target vessel revascularization, target lesion revascularization, target vessel failure, target lesion failure). At intermediate follow-up (2-3 years), EES was superior to ZES for reducing target lesion revascularization (RR = 1.28, 95% CI = 1.05-1.58, p < 0.05). At long-term follow-up (3-5 years), there were no significant differences between the two groups for any of the pooled outcomes (p > 0.05). CONCLUSION: ZES and EES have similar safety and efficacy at short, intermediate, and long-term follow-ups.

Cardiovascular outcomes of emergent vs elective transcatheter aortic valve replacement in severe aortic stenosis: regression matched meta-analysis.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has been highly increased as the recommended option for patients with a high surgical risk. This study aims to commit a systematic review and meta-analysis to assess the outcomes in severe aortic stenosis patients following emergency transcatheter aortic valve replacement (emergent TAVR) compared to elective TAVR or eBAV followed by elective TAVR. METHODS: We conducted a systematic literature search of PubMed, Embase, Cochrane CENTRAL, CINAHL, Science Direct, and Google Scholar. We included nine studies in the latest analysis that reported the desired outcomes. Outcomes were classified into primary outcomes: 30-day all-cause mortality and 30-day readmission rate, and secondary outcomes, which were further divided into (a) peri-procedural outcomes, (b) vascular outcomes, and (c) renal outcomes. Statistical analysis was performed using Stata v.17 (College State, TX) software. RESULTS: A total of 44,731 patients with severe aortic stenosis were included (emergent TAVR n = 4502; control n = 40045). 30-day mortality was significantly higher in the emergent TAVR group (OR: 2.62; 95% CI = 1.76-3.92; P < 0.01). Regarding post-procedural outcomes, the length of stay was significantly higher in the emergent TAVR group (Hedges's g: +4.73 days; 95% CI = +3.35 to +6.11; P < 0.01). With respect to vascular outcomes, they were similar in both groups. Regarding renal outcomes, both acute kidney injury (OR: 2.52; 95% CI = 1.59-4.00; P < 0.01) and use of renal replacement therapy (OR: 2.33; 95% CI = 1.87-2.91; P < 0.01) were significantly higher in emergent TAVR group as compared to the control group. CONCLUSION: Our study demonstrated that despite increased 30-day mortality and worse renal outcomes, the post-procedural outcomes were similar in emergent and elective TAVR groups. The increased mortality and worse renal outcomes are likely due to hemodynamic instability in the emergent group. The similarity of post-procedural outcomes is evidence of the safety of TAVR even in emergent settings.

Surgical versus transcatheter aortic valve replacement in low-risk Medicare beneficiaries.

OBJECTIVE: Recent approval of transcatheter aortic valve replacement (TAVR) in patients at low surgical risk has resulted in a rapid real-world expansion of TAVR in patients not otherwise examined in recent low-risk trials. We sought to evaluate the outcomes of surgical aortic valve replacement (SAVR) versus TAVR in low-risk Medicare beneficiaries. METHODS: Using the US Centers for Medicare and Medicaid Services claims database, we evaluated all beneficiaries undergoing isolated SAVR (n = 33,210) or TAVR (n = 77,885) (2018-2020). International Classification of Diseases 10th revision codes were used to define variables and frailty was defined by the validated Kim index. Doubly robust risk adjustment was performed with inverse probability weighting and multilevel regression models, as well as competing-risk time to event analysis. A low-risk cohort was identified to simulate recent low-risk trials. RESULTS: A total of 15,749 low-risk patients (8144 SAVR and 7605 TAVR) were identified. Comparison was performed with doubly robust risk adjustment accounting for all factors. TAVR was associated with lower perioperative stroke (odds ratio, 0.62; P < .001) and hospital mortality (odds ratio, 0.16; P < .001) compared with SAVR. However, risk-adjusted longitudinal analysis demonstrated TAVR was associated with higher late risk of stroke (hazard ratio, 1.65; P < .001), readmission for valve reintervention (hazard ratio, 1.88; P < .001), and all-cause mortality (hazard ratio, 1.54; P < .001) compared with SAVR. CONCLUSIONS: Among low-risk Medicare beneficiaries younger than age 75 years undergoing isolated AVR, SAVR was associated with higher index morbidity and mortality but improved 3-year risk-adjusted stroke, valve reintervention, and survival compared with TAVR.

Atrial Fibrillation Management During Surgical vs Transcatheter Aortic Valve Replacement.

BACKGROUND: Societal guidelines support atrial fibrillation (AF) treatment during surgical aortic valve replacement (SAVR). Recently, many patients with AF at low to intermediate risk are managed by transcatheter aortic valve replacement (TAVR). Therefore, we evaluated longitudinal outcomes in these populations. METHODS: The United States Centers for Medicare and Medicaid Services inpatient claims database was evaluated for all beneficiaries with AF undergoing TAVR or SAVR with/without AF treatment (2018-2020). Treatment of AF included concomitant left atrial appendage obliteration, with/without surgical ablation, or endovascular appendage occlusion and/or catheter ablation at any time. Diagnosis-related group and International Classification of Diseases, 10th Revision, codes defined procedures with doubly robust risk adjustment across each group. RESULTS: A total of 24,902 patients were evaluated (17,453 TAVR; 7,449 SAVR). Of patients undergoing SAVR, 3176 (42.6%) underwent AF treatment (SAVR+AF). Only 656 TAVR patients (4.5%) received AF treatment. Comparing well-balanced SAVR+AF vs SAVR vs TAVR, there were no differences in the in-hospital incidence of renal failure, bleeding, or stroke, but increased pacemaker requirement (odds ratio [OR], 3.45; P < .0001) and vascular injury (OR, 9.09; P < .0001) were noted in TAVR and higher hospital mortality (OR, 4.02; P < .0001) in SAVR+AF. SAVR+AF was associated with lower readmission for stroke compared with SAVR alone (hazard ratio [HR], 0.87; P = .029) and TAVR (HR, 0.68; P < .0001) and with improved survival vs TAVR (HR, 0.79; P = .019). CONCLUSIONS: In Medicare beneficiaries with AF requiring aortic valve replacement, SAVR+AF was associated with improved longitudinal survival and freedom from stroke compared with TAVR. SAVR+AF treatment should be considered first-line therapy for patients with AF requiring aortic valve replacement.

Heart failure, the global pandemic: A call to action consensus statement from the global presidential conclave at the platinum jubilee conference of cardiological society of India 2023.

Heart failure (HF) is emerging as a major public health problem both in high- and low - income countries. The mortality and morbidity due to HF is substantially higher in low-middle income countries (LMICs). Accessibility, availability and affordability issues affect the guideline directed therapy implementation in HF care in those countries. This call to action urges all those concerned to initiate preventive strategies as early as possible, so that we can reduce HF-related morbidity and mortality. The most important step is to have better prevention and treatment strategies for diseases such as hypertension, ischemic heart disease (IHD), type-2 diabetes, and rheumatic heart disease (RHD) which predispose to the development of HF. Setting up dedicated HF-clinics manned by HF Nurses, can help in streamlining HF care. Subsidized in-patient care, financial assistance for device therapy, use of generic medicines (including polypill strategy) will be helpful, along with the use of digital technologies.

Clinical characteristics and outcomes of patients requiring prolonged mechanical circulatory support after high-risk percutaneous coronary intervention.

BACKGROUND: There are limited data on the clinical characteristics and outcomes of patients who require prolonged mechanical circulatory support (MCS) after Impella-supported high-risk percutaneous coronary intervention (HR-PCI). AIMS: The aim of this study is to describe the contemporary clinical characteristics, outcomes, and predictors associated with prolonged MCS support after assisted HR-PCI. METHODS: Patients enrolled in the prospective, multicentre, clinical endpoint-adjudicated PROTECT III study who had undergone HR-PCI using Impella were evaluated. Patient and procedural characteristics and outcomes for those who received prolonged MCS beyond the duration of their index procedure were compared to those in whom MCS was successfully weaned and explanted at the conclusion of the index PCI. RESULTS: Among 1,155 patients who underwent HR-PCI with Impella between 2017 and 2020 and had sufficient data to confirm the duration of Impella support, 16.5% received prolonged MCS (mean duration 25.2±31.1 hours compared with 1.8±5.8 hours for those who only received intraprocedural MCS). Patients receiving prolonged support presented with more urgent indications (e.g., acute coronary syndromes [ACS], lower ejection fraction [EF], elevated baseline heart rate and lower systolic blood pressure). Use of the Impella CP, intraprocedural complications, periprocedural complications and in-hospital mortality were all more common amongst the prolonged MCS group. Prolonged MCS was associated with increased rates of major adverse cardiovascular and cerebrovascular events, cardiovascular death, and all-cause mortality at 90-day follow-up. CONCLUSIONS: Patients receiving prolonged MCS after Impella-supported HR-PCI presented with more ACS, reduced EF and less favourable haemodynamics. Additionally, they were more likely to experience intraprocedural and periprocedural complications as well as increased in-hospital and post-discharge mortality.

Cardiovascular Outcomes of Transcatheter Aortic Valve Implantation in Patients With Chronic Kidney Disease in Octogenarian Population.

Limited data are available regarding in-hospital outcomes of transcatheter aortic valve implantation (TAVI) in the octogenarian population with chronic kidney disease (CKD). We sought to study the cardiovascular outcomes of TAVI in CKD hospitalization with different stages at the national cohort registry. We used the National Inpatient Sample database to compare TAVI CKD low-grade (LG) (stage I to IIIa, b) versus TAVI CKD high-grade (HG) (stage IV to V) in octogenarians. Outcomes such as inpatient mortality, cardiogenic shock, new permanent pacemaker implantation, acute kidney injury), sudden cardiac arrest, mechanical circulatory support, major bleeding, transfusion, and resource utilization were compared between the 2 cohorts. A total of 74,766 octogenarian patients (TAVI CKD-HG n = 12,220; TAVI CKD-LG n = 62,545) were included in our study. On matched analysis, TAVI CKD-HG had higher odds of in-hospital mortality (adjusted odds ratio [aOR] 2.18, 95% confidence interval [CI] 1.0-2.5, p <0.0001), cardiogenic shock (aOR 1.22, 95% CI 1.07 to 1.39, p = 0.0019), permanent pacemaker implantation (aOR 1.14, 95% CI 1.06 to 1.23, p = 0.0006), acute kidney injury (aOR 1.19, 95% CI 1.13 to 1.27, p <0.0001), sudden cardiac arrest (aOR 1.32, 95% CI 1.09 to 1.61, p = 0.004), major bleeding (aOR 1.1, 95% CI 1.006 to 1.22, p <0.0368) and higher rates of blood transfusion (aOR 1.62, 95% CI 1.5 to 1.75, p <0.0001) when compared with the TAVI CKD-LG cohort. However, there was no statistically significant difference in the odds of cerebrovascular accident and mechanical circulatory support use between the 2 groups.

Multimodality assessment of high- vs. low-gradient aortic stenosis using echocardiography and cardiac CT.

BACKGROUND: Aortic valve area (AVA) using CT-LVOT area (AVACT-LVOT) <1.2 â€‹cm2 has been shown comparable to echocardiography AVA of <1.0 â€‹cm2 for severe aortic stenosis (AS). Current study evaluates how AS diagnosis will be affected when we substitute CT-LVOT with echo derived LVOT. METHODS: We retrospectively studied 367 patients who underwent cardiac CTA and echocardiogram for assessment of high- and low-gradient AS (HG-AS and LG-AS). AVACT-LVOT was derived from CT-LVOT area and echo doppler data. Three AVACT-LVOT categories were created (<1.0, 1.0-1.2 and â€‹> â€‹1.2 â€‹cm2). Outcomes were defined as composite of all-cause mortality and/or valve intervention. RESULTS: Median echocardiographic profiles were consistent with severe AS across three AVACT-LVOT categories for HG-AS. HG-AS patients with AVACT-LVOT >1.2 â€‹cm2 had larger median CT-LVOT area (5.06 â€‹cm2) and AVC (2917AU). Among LG-AS with AVACT-LVOT â€‹≤1.2 cm2, 57% met echo criteria for low-flow LG-AS and 63% met criteria for severe AS using aortic valve calcium (AVC). Additionally, 45% with AVACT-LVOT >1.2 â€‹cm2 had larger median CT-LVOT area (5.43 â€‹cm2) and AVC (2389AU). Patients with AVACT-LVOT >1.2 â€‹cm2 and high AVC had large body surface area and were mostly characterized as severe with indexed AVA and AVC. Stroke volume index using CT-LVOT reclassified 70% of low-flow, LG-AS as normal flow, LG-AS. Composite outcomes were higher among patients with AVACT-LVOT ≤1.2 â€‹cm2 (p â€‹< â€‹0.01), however, with no superior net reclassification improvement compared to AVAecho <1.0 â€‹cm2. CONCLUSION: AVACT-LVOT ≤1.2 â€‹cm2 is a reasonable CT criterion for severe AS. Large LVOT with elevated AVC identified a severe AS phenotype despite an AVACT-LVOT >1.2 â€‹cm2, best characterized by indexed AVA and AVC.

Outcomes of Transcatheter Aortic Valve Replacement With and Without Index Chronic Total Occlusion of Coronary Artery: A Propensity Matched Analysis.

Transcatheter aortic valve replacement (TAVR) utilization is increasing, along with procedural success. Coronary angiography is frequently performed before the TAVR procedure for coronary artery disease workup. Chronic total occlusion (CTO) of the coronary artery shares common risk factors with aortic stenosis and could be challenging, especially in terms of procedural safety. The outcomes of TAVR among patients with concomitant CTO are not extensively studied. We analyzed the National Inpatient Sample database between October 2015 and December 2020 to evaluate the clinical characteristics, procedural safety, and outcomes among patients who underwent TAVR who had concomitant CTO lesions. A total of 304,330 TAVRs were performed between 2015 and 2020, 5,235 of which (1.72%) were in patients with TAVR-CTO and 299,095 (98.28%) in those with TAVR-no CTO. After propensity matching, there was no difference in the odds of in-hospital mortality (adjusted odds ratio [aOR] 1.28, 95% confidence interval [CI] 0.94 to 1.75, p = 0.11). However, TAVR-CTO was associated with an increased incidence of acute myocardial infarction (aOR 1.27, 95% CI 1.05 to 1.53, p = 0.01), cardiac arrest (aOR, 2.60, 95% CI 1.64 to 4.11, p <0.0001), and need for mechanical circulatory support (aOR 2.6, 95% CI 1.88 to 3.59, p <0.0001). There was no difference in the incidence of stroke, major bleeding, complete heart block, or requirement for permanent pacemaker between the 2 groups. However, the TAVR-CTO cohort had a slightly greater length of stay and total hospitalization cost. TAVR is a relatively safe procedure among those with concomitant CTO lesions; however, it is associated with a greater incidence of acute myocardial infarction, cardiac arrest, and requirement for mechanical circulatory support.

Lead Cap Use in Interventional Cardiology: Time to Protect Our Head in the Cardiac Catheterisation Laboratory?

Background: Radiation exposure is an occupational hazard for interventional cardiologists and cardiac catheterisation laboratory staff that can manifest with serious long-term health consequences. Personal protective equipment, including lead jackets and glasses, is common, but the use of radiation protective lead caps is inconsistent. Methods: A systematic review qualitative assessment of five observational studies using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines protocol was performed. Results: It was concluded that lead caps significantly reduce radiation exposure to the head, even when a ceiling-mounted lead shield was present. Conclusion: Although newer protective systems are being studied and introduced, tools, such as lead caps, need to be strongly considered and employed in the catheterisation laboratory as mainstay personal protective equipment.

Predictors and Outcomes of Extracorporeal Membrane Oxygenation in COVID-19 Patients With ARDS: A Propensity-Matched Analysis of National Inpatient Sample.

Extracorporeal membrane oxygenation (ECMO) is a significant treatment modality for COVID-19 patients on ventilators. The current data is limited for understanding the indicators and outcomes of ECMO in COVID-19 patients with acute respiratory distress syndrome (ARDS). The National Inpatient Sample (NIS) database from 2020 was queried in this study. Among 1,666,960 patients admitted with COVID-19, 99,785 (5.98%) patients developed ARDS, and 60,114 (60.2%) were placed on mechanical ventilation. Of these mechanically ventilated COVID-ARDS patients, 2580 (4.3%) were placed on ECMO. Patients with ECMO intervention had higher adjusted odds (aOR) of blood loss anemia (aOR 9.1, 95% CI: 6.16-13.5, propensity score-matched (PSM) 42% vs 5.4%, P < 0.001), major bleeding (aOR 3.79, 95% CI: 2.5-5.6, PSM 19.9% vs 5.9%, P < 0.001) and acute liver injury (aOR 1.7, 95% CI: 1.14-2.6 PSM 14% vs 6%, P = 0.009) compared to patients without ECMO intervention. However, in-hospital mortality, acute kidney injury, transfusions, acute MI, and cardiac arrest were insignificant. On subgroup analysis, patients placed on veno-arterial ECMO had higher odds of cardiogenic shock (aOR 13.4, CI 3.95-46, P < 0.0001), cardiac arrest (aOR 3.5, CI 1.45-8.47, P = 0.0057), acute congestive heart failure (aOR 4.18, CI 1.05-16.5, P = 0.042) and lower odds of major bleeding (aOR 0.26, CI 0.07-0.92). However, there was no significant difference in mortality, intracranial hemorrhage, and acute MI. Further studies are needed before considering COVID-19 ARDS patients for placement on ECMO.

Cardiovascular Outcomes of Transulnar Versus Transradial Percutaneous Coronary Angiography and Intervention: A Regression Matched Meta-Analysis.

Transradial access (TRA) and transulnar access (TUA) are in close vicinity, but TRA is the preferred intervention route. The cardiovascular outcomes and access site complications of TUA and TRA are understudied. Databases, including MEDLINE and Cochrane Central registry, were queried to find studies comparing safety outcomes of both procedures. The outcome of interest was in-hospital mortality and access site bleeding. Secondary outcomes were all-cause major adverse cardiovascular events, crossover rate, artery spasm, access site large hematoma, and access site complications between TUA and TRA. A random-effect model was used with regression to report unadjusted odds ratios (ORs) by limiting confounders and effect modifiers, using software STATA V.17. A total of 4,796 patients in 8 studies were included in our analysis (TUA = 2,420 [50.4%] and TRA = 2,376 [49.6%]). The average age was 61.3 and 60.1 years and the patients predominantly male (69.2% vs 68.4%) for TUA and TRA, respectively. TUA had lower rates of local access site bleeding (OR 0.58, 95% confidence interval 0.34 to 0.97, I2 = 1.89%, p = 0.04) but higher crossover rate (OR 1.80, 95% confidence interval 1.04 to 3.11, I2 = 75.37%, p = 0.04) than did TRA. There was no difference in in-hospital mortality, all-cause major adverse cardiovascular events, arterial spasm, and large hematoma between both cohorts. Furthermore, there was no difference in procedural time, fluoroscopy time, and contrast volume used between TUA and TRA. TUA is a safer approach, associated with lower access site bleeding but higher crossover rates, than TRA. Further prospective studies are needed to evaluate the safety and long-term outcomes of both procedures.

Trends in Cardiogenic Shock-Related Mortality in Patients With Acute Myocardial Infarction in the United States, 1999 to 2019.

Data on mortality trends in patients with acute myocardial infarction (AMI) with cardiogenic shock (CS) are scant. This study aimed to assess the trends in CS-AMI-related mortality in United States (US) subjects over the latest 21 years. Mortality data of US subjects with AMI listed as the underlying cause of death and CS as contributing cause were obtained from the Centers for Disease Control and Prevention WONDER (Wide-Ranging Online Data for Epidemiologic Research) dataset from January 1999 to December 2019. CS-AMI-related age-adjusted mortality rates (AAMRs) per 100,000 US population were stratified by gender, race and ethnicity, geographic areas, and urbanicity. Nationwide annual trends were assessed as annual percent change (APC) and average APC with relative 95% confidence intervals (CIs). Between 1999 and 2019, CS-AMI was listed as the underlying cause of death in 209,642 patients, (AAMR of 3.01 per 100,000 people [95% CI 2.99 to 3.02]). AAMR from CS-AMI remained stable from 1999 to 2007 (APC -0.2%, [95% CI -2.0 to 0.5], p = 0.22) and then significantly increased (APC 3.1% [95% CI 2.6 to 3.6], p <0.0001), especially in male patients. Starting in 2009, the AAMR increase was more pronounced in those <65 years, Black Americans, and residents of rural areas. The higher AAMRs were clustered in the South (average APC 4.5%, [95% CI 4.4 to 4.6]) of the country. In conclusion, CS-AMI-related mortality in US patients increased from 2009 to 2019. Targeted health policy measures are needed to address the rising burden of CS-AMI in US subjects.

Long term outcomes of percutaneous coronary intervention vs coronary artery bypass grafting in patients with diabetes mellitus with multi vessels diseases: A meta-analysis.

Aims: Long term cardiovascular outcome comparison of multivessel coronary disease among patients with diabetes mellitus (DM) undergoing percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) is limited. The objective of this study was to compare the long-term cardiovascular outcome PCI vs CABG among DM patients with multivessel disease. Method and results: Online databases were explored to identify studies that compared cardiovascular outcomes between PCI and CABG among patients with DM. The primary outcome was all-cause mortality. Secondary outcomes included major adverse cardiovascular and cerebrovascular events (MACCE), myocardial infarction (MI), rate of revascularization, cardiac death, and cerebrovascular accident (CVA). A total of 27 studies with 37,091 (PCI n = 19,838 (53 %) and CABG n = 17,253 (47 %)) patients were included. The mean age was 64 ± 5.9 years for PCI group and 63.8 ± 5.3 years for CABG group; and, predominantly male (71.22 % vs 74.29 %) for PCI and CABG respectively. The most common comorbidity was hypertension (64.35 % vs 62.88 %) in both PCI and CABG respectively. Compared with CABG, PCI group had a higher odds of overall all-cause mortality (OR 1.18, 95 % CI 1.02-1.37, p = 0.03), MACCE (OR 1.52, 95 % CI 1.31-1.75, p = 0.00), MI (OR 1.85, 95 % CI 1.46-2.36, p = 0.00), repeat revascularization (OR 3.08, 95 % CI 2.34-4.05, p = 0.00) and cardiac death (OR 1.27, 95 % 1.02-1.59, p = 0.04), while CVA (0.57, 95 % CI 0.37-0.86, p = 0.01) was higher with CABG. Conclusion: Diabetic patients with multivessel coronary artery disease have worse outcomes undergoing PCI as compared to CABG. However, CVA was significantly higher with CABG. CABG remains the preferred management among eligible patients with multivessel disease and DM.

Meta-Analysis on the Impact of Coronary Bypass Graft Markers on Angiographic Procedural Outcomes.

Utilization of radio-opaque coronary artery bypass graft markers is known to decrease the amount of contrast dye required to complete the procedure. The practice of marking bypass grafts varies significantly among surgeons. Limited data exist comparing the outcomes of percutaneous coronary intervention with and without coronary artery bypass graft (CABG) markers. We sought to explore the impact of proximal radio-opaque markers placed during CABG in subsequent percutaneous coronary intervention procedural risks. In our understanding of the current literature, this is the first meta-analysis conducted to evaluate the association between procedural angiographic metrics and CABG radio-opaque markers. We performed a query of MEDLINE and Scopus databases through August 2022 to identify relevant studies evaluating procedural metrics among patients with previous CABG with and without radio-opaque markers who underwent angiography. The primary outcomes of interest were fluoroscopy time, amount of contrast, and duration of angiography. We identified a total of 4 studies with 2,046 patients with CABG (CABG with markers n = 688, CABG without markers n = 1,518).2-5 Total fluoroscopy time was significantly reduced among patients with CABG markers compared with those with no markers (odds ratio [OR] -3.63, p <0.0001). The duration of angiography (OR -36.39, p >0.10) was reduced, although the result was not statistically significant. However, the amount of contrast utilization was significantly reduced (OR -33.41, p <0.0001). In patients who underwent CABG with radio-opaque markers, angiographic procedural metrics were improved, including reduced fluoroscopic time and the amount of contrast agent required compared with no markers.
