In-Hospital Outcomes of Combined Coronary Revascularization and Transcatheter Aortic Valve Implantation in Inpatient Nationwide Analysis.

Transcatheter aortic valve implantation (TAVI) is accepted as an alternative to surgery, but data on combined percutaneous coronary interventions (PCI) and TAVI during the same in-hospital stay are still lacking. Using the national inpatient sample (NIS) database, we identified all TAVI encounters and compared in-hospital outcomes of patients who had TAVI only to patients who had TAVI and PCI. We used multivariable logistic regression analysis to calculate the adjusted odds ratio (aOR). Of 291,810 patient encounters with TAVI, 13,114 (4.5%) had combined PCI during the same index admission. The average age was 79.61 ± 8.61 years in the TAVI-only vs 80.25 ± 8.73 years in the combined TAVI-PCI group. Combined TAVI and PCI was associated with higher in-hospital mortality (4.5% vs 1.8%, aOR: 2.3), stroke (4.7% vs 2.9%, aOR: 1.4), net adverse events (NAE) (20.2% vs 5.7%, aOR: 3.6), major bleeding (40.1% vs 24.3%, aOR: 1.8), vascular complications (10.6% vs 2.5%, aOR: 3.9), acute kidney injury (AKI) (23.3% vs 11.7%, aOR: 2.1), hemodialysis (HD) (4.2% vs 2.4%, aOR: 1.4), postoperative cardiogenic shock (1.2% vs 0.4%, aOR: 2.8), need for mechanical circulatory support (6.9% vs 1%, aOR: 7); p-value < 0.001 for all. The utilization of permanent pacemakers was similar between the groups (9.8% vs 9.2%, aOR: 1; p = 0.6). Combining TAVI and PCI during the same index admission is associated with worse outcomes. The decision to do PCI for patients undergoing TAVI should be individualized and tailored based on the patient's clinical conditions.

Noninvasive Evaluation of Cardiac Chamber Pressures Using Subharmonic-Aided Pressure Estimation With Definity Microbubbles.

BACKGROUND: Noninvasive and accurate assessment of intracardiac pressures has remained an elusive goal of noninvasive cardiac imaging. OBJECTIVES: The purpose of this study was to investigate if errors in intracardiac pressures obtained noninvasively using contrast microbubbles and the subharmonic-aided pressure estimation (SHAPE) technique are <5 mm Hg. METHODS: In a nonrandomized institutional review board-approved clinical trial (NCT03243942), patients scheduled for a left-sided and/or right-sided heart catheterization procedure and providing written informed consent were included. A standard-of-care catheterization procedure was performed advancing clinically used pressure catheters into the left and/or right ventricles and/or the aorta. After pressure catheter placement, patients received an infusion of Definity microbubbles (n = 56; 2 vials diluted in 50 mL of saline; infusion rate: 4-10 mL/min) (Lantheus Medical Imaging). Then SHAPE data was acquired using a validated interface developed on a SonixTablet scanner (BK Medical Systems) synchronously with the pressure catheter data. A conversion factor (mm Hg/dB) was derived from SHAPE data and measurements with a SphygmoCor XCEL PWA device (ATCOR Medical) and was combined with SHAPE data from the left and/or the right ventricles to obtain clinically relevant systolic and diastolic ventricular pressures. RESULTS: The mean value of absolute errors for left ventricular minimum and end diastolic pressures were 2.9 ± 2.0 and 1.7 ± 1.2 mm Hg (n = 26), respectively, and for right ventricular systolic pressures was 2.2 ± 1.5 mm Hg (n = 11). Two adverse events occurred during Definity infusion; both were resolved. CONCLUSIONS: These results indicate that the SHAPE technique with Definity microbubbles is encouragingly efficacious for obtaining intracardiac pressures noninvasively and accurately.

Palliative Care Use in Patients With Acute Myocardial Infarction and Do-Not-Resuscitate Status From a Nationwide Inpatient Cohort.

OBJECTIVE: To examine the predictors, treatments, and outcomes of the use of palliative care in patients hospitalized with acute myocardial infarction (AMI) who had a do-not-resuscitate (DNR) order. PATIENTS AND METHODS: Using the National (Nationwide) Inpatient Sampling database for 2015-2018, we examined the predictors, in-hospital procedures, and outcomes of palliative care recipients among patients with AMI who had a DNR order. RESULTS: We identified 339,270 admissions with AMI that had a DNR order, including patients who received palliative care (n=113,215 [33.4%]). Compared with patients who did not receive palliative care, these patients were more frequently younger (median age, 81 vs 83 years; P<.001), were less likely to be female (50.9% [57,626 of 113,215] vs 54.7% [123,652 of 226,055]; P<.001), and were more likely to present with cardiac arrest (11.6% [13,133 of 113,215] vs 6.9% [15,598 of 226,055]; P<.001). Patients were more likely to receive palliative care at a large (odds ratio [OR], 1.47; 95% CI, 1.44 to 1.50) or teaching (OR, 2.10; 95% CI, 2.04 to 2.16) hospitals compared with small or rural ones. Patients receiving palliative care were less likely to be treated invasively, with reduced rates of invasive coronary angiography (OR, 0.46; 95% CI, 0.45 to 0.47) and percutaneous coronary intervention (OR, 0.47; 95% CI, 0.45 to 0.48), and were more likely to die in the hospital (52.4% [59,325 of 113,215] vs 22.9% [51,766 of 226,055]). CONCLUSION: In patients who had a DNR status and were hospitalized and received a diagnosis of AMI, only one-third received palliative care.

Outcomes and Discriminatory Accuracy of the CHA2DS2VASc Score in Atrial Fibrillation and Cancer.

Background: Atrial fibrillation (AF) is highly prevalent among cancer patients. The role of traditional risk stratification scores in the context of different cancer types in these patients remains unknown. Objectives: The purpose of this study was to determine the discriminative accuracy of the CHA2DS2VASc score for ischemic stroke using receiver operating characteristic and area under the curve. Methods: The National Readmission Database (2015-2019) was used to identify all AF patients stratified by the cancer diagnosis, type, and CHA2DS2VASc category (low; moderate; high risk). Outcomes at 30-day readmission were compared between cancer and noncancer groups using hierarchical multivariable logistic regression to calculate adjusted odds ratios (aORs) and 95% CIs. Results: A total of 6,996,088 AF patients were identified at index admission. Of these, 4,242,630 (642,237 cancer, 3,600,393 noncancer) were readmitted at 30 days. Cancer patients (92.1%) had a higher proportion of high CHA2DS2VASc scores compared with their noncancer counterparts (89.8%, P < 0.001). The 30-day readmission rate and incidence of major bleeding in cancer patients were significantly higher compared with their corresponding noncancer group across all CHA2DS2VASc categories. Among the different cancer types, hematological and lung cancer had a high propensity for major bleeding. The odds of ischemic stroke were lower in the cancer group across high (1.9% vs 2.4%; aOR: 0.78; 95% CI: 0.76-0.79; P < 0.0001), moderate (0.8% vs 1.3%; aOR: 0.57; 95% CI: 0.50-0.64; P < 0.0001), and low (0.4% vs 0.9%; aOR: 0.46; 95% CI: 0.34-0.62; P < 0.0001) risk category relative to the noncancer group irrespective of type of cancer. CHA2DS2VASc category had a statistically significant discriminatory accuracy for ischemic stroke in both cancer and noncancer patients. Conclusions: Cancer patients with AF are at a higher risk of readmission and major bleeding. The risk of ischemic stroke during readmission appears to be lower than noncancer patients. These findings may have implications for anticoagulant therapy in cancer patients.

Trends and Outcomes of TAVI and SAVR in Cancer and Noncancer Patients: A Nationwide Analysis.

Background: Patients with severe aortic stenosis and cancer are often denied surgical aortic valve replacement (SAVR) due to a prohibitive risk of perioperative mortality. Objectives: The purpose of this study was to determine the safety of transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis and cancer. Methods: The Nationwide Inpatient Sample database (2002-2018) was used to study the outcomes of TAVI vs SAVR in patients with active or prior history of prostate, lung, colorectal, breast, and renal cancer. A propensity score-matched analysis to calculate adjusted odds ratios (aORs) for major adverse cardiovascular events (MACEs) and its components. Results: A total of 1,505,995 crude population and a subset of 345,413 noncancer and 33,565 cancer patients were selected on propensity score-matched analysis. The yearly trend showed a steep increase in the utilization of TAVI. Compared with SAVR, TAVI had a lower risk of in-hospital mortality in prostate cancer, while there was no difference among other cancer types. Patients with lung (aOR: 0.65; 95% CI: 0.43-0.97) and prostate cancer (aOR: 0.79; 95% CI: 0.66-0.96) had lower, while colorectal cancer (aOR: 1.43; 95% CI: 1.08-1.90) had higher odds of MACE with TAVI. The incidence of major bleeding was lower with TAVI (except for lung cancer), while the risk of stroke was similar (except for colorectal cancer) between TAVI and SAVR. Conclusions: TAVI in patients with prostate, breast, lung, and renal cancer appears to be a reasonable alternative to SAVR with lower or similar risks of mortality and MACE.

Impact of QRS Duration on Non-ST-Segment Elevation Myocardial Infarction (from a National Registry).

QRS duration (QRSd) is ill-defined and under-researched as a prognosticator in patients with non-ST-segment myocardial infarction (NSTEMI). We analyzed 240,866 adult (≥18 years) hospitalizations with non-ST-segment elevation myocardial infarction using data from the United Kingdom Myocardial Infarction National Audit Project. Clinical characteristics and all-cause in-hospital mortality were analyzed according to QRSd, with 38,023 patients presenting with a QRSd >120 ms and 202,842 patients with a QRSd <120 ms. Patients with a QRSd >120 ms were more frequently older (median age of 79 years vs 71 years, p <0.001), and of white ethnicity (93% vs 91%, p <0.001). Patients with a QRSd <120 ms had higher frequency of use of aspirin (97% vs 95%, p <0.001), P2Y12 inhibitor (93% vs 89%, p <0.001), angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (82% vs 81%, p <0.001) and ß blockers (83% vs 78%, p <0.001). Invasive management strategies were more likely to be used in patients with QRSd <120 ms including invasive coronary angiography (72% vs 54%, p <0.001), percutaneous coronary intervention (46% vs 33%, p <0.001) and coronary artery bypass graft surgery (8% vs 6%, p <0.001). In a propensity score matching analysis, there were no differences between the 2 groups in the adjusted rates of in-hospital all-cause mortality (odds ratio 0.94, 95% confidence interval 0.86 to 1.01) or major adverse cardiac events (odds ratio 0.94, 95% confidence interval 0.85 to 1.02) during the index admission. In conclusion, prolonged QRSd >120 ms in the context of non-ST-segment myocardial infarction is not associated with worse in-hospital mortality or the outcomes of major adverse cardiac events.

Transcatheter valve-in-valve implantation versus redo surgical mitral valve replacement in patients with failed mitral bioprostheses.

BACKGROUND: Data on the safety of valve-in-valve transcatheter mitral valve replacement (ViV-TMVR) compared with redo surgical mitral valve replacement (SMVR) in patients with a history of bioprosthetic mitral valve (MV) remain limited. AIMS: We aimed to evaluate the in-hospital, 30-day and 6-month readmission outcomes of ViV-TMVR compared with redo-SMVR in a real-world cohort. METHODS: The Nationwide Readmission Database was utilised, analysing data from 2015 to 2019. To determine the adjusted odds ratio (aOR), we used the propensity-matched analysis for major outcomes at index hospitalisation, 30 days, and 6 months during the episode of readmission. RESULTS: A total of 3,691 patients were included, of these, 24.2% underwent ViV-TMVR and 75.8% underwent redo-SMVR. Patients undergoing ViV-TMVR were older with higher rates of comorbidities. The mean length of stay (15 days vs 4 days) and cost of hospitalisation ($76,558 vs $46,743) were significantly higher for redo-SMVR. The rate of in-hospital all-cause mortality was also significantly lower in ViV-TMVR (2.6% vs 7.3%). By contrast, 30-day all-cause mortality during the episode of readmission (aOR 1.01, 95% confidence interval [CI]: 0.40-2.55) and all-cause readmission rates (aOR 0.82, 95% CI: 0.66-1.02) were similar between both groups. The incidence of all-cause readmissions at 6 months (aOR 0.83, 95% CI: 0.65-1.05) and all-cause mortality during the episode of readmission at 6 months (aOR 1.84, 95% CI: 0.54-6.36) were also comparable. The utilisation of the ViV-TMVR procedure increased significantly during our study duration, from 5.2% to 36.8%, (ptrend<0.01). CONCLUSIONS: ViV-TMVR is associated with lower odds of in-hospital mortality, complications, and resource utilisation. The all-cause readmissions and 30-day and 6-month mortality during the episode of readmissions were comparable between both groups.

Trend, predictors, and outcomes of combined mitral valve replacement and coronary artery bypass graft in patients with concomitant mitral valve and coronary artery disease: a National Inpatient Sample database analysis.

Aims: Combined mitral valve replacement (MVR) and coronary artery bypass graft (CABG) procedures have been the norm for patients with concomitant mitral valve disease (MVD) and coronary artery disease (CAD) with no large-scale data on their safety and efficacy. Methods and results: The National Inpatient Sample database (2002-18) was queried to identify patients undergoing MVR and CABG. The major adverse cardiovascular events (MACE) and its components were compared using a propensity score-matched (PSM) analysis to calculate adjusted odds ratios (OR). A total of 6 145 694 patients (CABG only 3 971 045, MVR only 1 933 459, MVR + CABG 241 190) were included in crude analysis, while a matched cohort of 724 237 (CABG only 241 436, MVR only 241 611 vs. MVR + CABG 241 190) was selected in PSM analysis. The combined MVR + CABG procedure had significantly higher adjusted odds of MACE [OR 1.13, 95% confidence interval (CI) 1.11-1.14 and OR 1.96, 95% CI 1.93-1.99] and in-hospital mortality (OR 1.29, 95% CI 1.27-1.31 and OR 2.1, 95% CI 2.05-2.14) compared with CABG alone and MVR alone, respectively. Similarly, the risk of post-procedure bleeding, major bleeding, acute kidney injury, cardiogenic shock, sepsis, need for intra-aortic balloon pump, mean length of stay, and total charges per hospitalization were significantly higher for patients undergoing the combined procedure. These findings remained consistent on yearly trend analysis favouring the isolated CABG and MVR groups. Conclusion: Combined procedure (MVR + CABG) in patients with MVD and CAD appears to be associated with worse in-hospital outcomes, increased mortality, and higher resource utilization compared with isolated CABG and MVR procedures. Randomized controlled trials are needed to determine the relative safety of these procedures in the full spectrum of baseline valvular and angiographic characteristics.

Mortality after transcatheter aortic valve replacement for aortic stenosis among patients with malignancy: a systematic review and meta-analysis.

BACKGROUND: With advancements in cancer treatment, the life expectancy of oncology patients has improved. Thus, transcatheter aortic valve replacement (TAVR) may be considered as a feasible option for oncology patients with severe symptomatic aortic stenosis (AS). We aim to evaluate the difference in short- and long-term all-cause mortality in cancer and non-cancer patients treated with TAVR for severe AS. METHODS: Medline, PubMed, and Cochrane Central Register of Controlled Trials were searched for relevant studies. Patients with cancer who underwent treatment with TAVR for severe AS were included and compared to an identical population without cancer. The primary endpoints were short- and long-term all-cause mortality. RESULTS: Of 899 studies included, 8 met inclusion criteria. Cancer patients had significantly higher long-term all-cause mortality after TAVR when compared to patients without cancer (risk ratio [RR] 1.43; 95% confidence interval (CI) 1.26-1.62; P < 0.01). Four studies evaluated short-term mortality after TAVR and demonstrated no difference in it in patients with and without cancer (RR 0.72; 95% CI 0.47-1.08; P = 0.11). CONCLUSION: Patients with cancer and severe AS have higher long-term all-cause mortality after TAVR. However, we found no difference in short-term all-cause mortality when comparing patients with and without cancer. The decision to perform TAVR in cancer patients should be individualized based on life expectancy and existing co-morbidities.

Percutaneous coronary intervention of totally occluded coronary venous bypass grafts: An exercise in futility?

BACKGROUND: Percutaneous coronary intervention (PCI) of diseased saphenous vein grafts (SVG) continues to pose a clinical challenge. Current PCI guidelines give a class III recommendation against performing PCI on chronically occluded SVG. However, contemporary outcomes after SVG intervention have incrementally improved with distal protection devices, intracoronary vasodilators, drug-eluting stents, and prolonged dual antiplatelet therapy. AIM: To reassess the procedural and long-term outcomes of PCI for totally occluded SVG with contemporary techniques. METHODS: This was a retrospective observational study conducted at a single university hospital. The study population consisted of 35 consecutive patients undergoing PCI of totally occluded SVG. Post-procedure dual antiplatelet therapy was continued for a minimum of one year and aspirin was continued indefinitely. Clinical outcomes were assessed at a mean follow-up of 1221 ± 1038 d. The primary outcome was freedom from a major adverse cardiac event (MACE) defined as the occurrence of any of the following: death, myocardial infarction, stroke, repeat bypass surgery, repeat PCI, or graft reocclusion. RESULTS: The study group included 29 men and 6 women with a mean age of 69 ± 12 years. Diabetes was present in 14 (40%) patients. All patients had Canadian Heart Classification class III or IV angina. Clinical presentation was an acute coronary syndrome in 34 (97%) patients. Mean SVG age was 12 ± 5 years. Estimated duration of occlusion was acute (< 24 h) in 34% of patients, subacute (> 24 h to 30 d) in 26%, and late (> 30 d) in 40%. PCI was initially successful in 29/35 SVG occlusions (83%). Total stent length was 52 ± 35 mm. Intraprocedural complications of distal embolization or no-reflow occurred in 6 (17%) patients. During longer term follow-up, MACE-free survival was only 30% at 3 years and 17% at 5 years. CONCLUSION: PCI of totally occluded SVG can be performed with a high procedural success rate. However, its clinical utility remains limited by poor follow-up outcomes.

Trends in cardiovascular mortality of cancer patients in the US over two decades 1999-2019.

BACKGROUND: Cancer is the second most common cause of death globally after cardiovascular disease, and cancer patients are at an increased risk of CV death. This recognition has led to publication of cardio-oncological guidelines and to the widespread adoption of dedicated cardio-oncology services in many institutes. However, it is unclear whether there has been a change in the incidence of CV death in cancer patients. METHODS AND RESULTS: Using Centers for Disease Control and Prevention Wide-Ranging, Online Data for Epidemiologic Research (CDC WONDER) Multiple Cause of Death dataset, we determined national trends in age-standardised mortality rates attributed to cardiovascular diseases in patients with and without cancer, from 1999 to 2019, stratified by cancer type, age, gender, race, and place of residence (state and urbanisation status). Among more than 17.8 million cardiovascular deaths in the United States, 13.6% were patients with a concomitant cancer diagnosis. During the study period, among patients with cancer, the age-adjusted mortality rate dropped by 52% (vs 38% in patients with no cancer). In cancer patients, age-adjusted mortality rate dropped more significantly among patients with gastrointestinal, breast, and prostate malignancy than among patients with haematological malignancy (59%-63% vs. 41%). Similar reduction was observed in both genders (53%-54%), but more prominent reduction was observed in older patients and in those living in metro areas. CONCLUSIONS: Our findings emphasise the role of multidisciplinary management of cancer patients. Widespread adoption of cardio oncology services have the potential to impact the inherent risk of increased CV mortality in both cancer patients and survivors.

Comparative analysis of revascularization with percutaneous coronary intervention versus coronary artery bypass surgery for patients with end-stage renal disease: a nationwide inpatient sample database.

BACKGROUND: The role of percutaneous coronary intervention (PCI) vs coronary artery bypass grafting (CABG) in patients with coronary artery disease (CAD) and concomitant end-stage renal disease (ESRD) remains unknown. RESEARCH DESIGN & METHODS: The National Inpatient Sample (NIS) (2002-2017) was queried to identify all cases of CAD and ESRD. The relative merits of PCI vs CABG were determined using a propensity-matched multivariate logistic regression model. Adjusted odds ratios (aOR) for mortality and other in-hospital complications were calculated. RESULTS: A total of 350,623 [CABG = 112,099 (32%) and PCI = 238,524 (68%)] hospitalizations were included in the analysis. The overall adjusted odds for major bleeding (aOR 1.28, 95% CI 1.25-1.31, P < 0.0001), post-procedure bleeding (aOR 5.19, 95% CI 4.93-5.47, P < 0.0001), sepsis (aOR 1.29, 95% CI 1.26-1.33, P < 0.0001), cardiogenic shock (aOR 1.23, 95% CI 1.20-1.26, P < 0.0001), and in-hospital mortality (aOR 1.65, 95% CI 1.61-1.69, P < 0.0001) were significantly higher for patients undergoing CABG compared with PCI. The need for intra-aortic balloon pump (IABP) placement (aOR 2.52, 95% CI 2.45-2.59, P < 0.001) was higher in the CABG group, while the adjusted odds of vascular complications were similar between the two groups (aOR 0.99, 95% CI 0.94-1.06, P = 0.82). As expected, patients undergoing CABG had a higher mean length of stay and mean cost of hospitalization. CONCLUSION: CABG in ESRD may be associated with higher in-hospital complications, increased length of stay, and higher resource utilization.

Meta-analysis comparing valve-in-valve TAVR and redo-SAVR in patients with degenerated bioprosthetic aortic valve.

INTRODUCTION: The comparative efficacy and safety of valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) and redo-surgical AVR (redo-SAVR) in patients with degenerated bioprosthetic aortic valves remain unknown. METHOD: Digital databases were searched to identify relevant articles. Unadjusted odds ratios for dichotomous outcomes were calculated using a random effect model. A total of 11 studies comprising 8326 patients (ViV-TAVR = 4083 and redo-SAVR = 4243) were included. RESULTS: The mean age of patients undergoing ViV-TAVR was older, 76 years compared to 73 years for those undergoing SAVR. The baseline characteristics for patients in ViV-TAVR vs. redo-SAVR groups were comparable. At 30-days, the odds of all-cause mortality (OR 0.45, 95% CI 0.30-0.68, p = .0002), cardiovascular mortality (OR 0.44, 95% CI 0.26-0.73, p = .001) and major bleeding (OR 0.29, 95% CI 0.15-0.54, p = .0001) were significantly lower in patients undergoing ViV-TAVR compared to redo-SAVR. There were no significant differences in the odds of cerebrovascular accidents (OR 0.91, 95% CI 0.52-1.58, p = .74), myocardial infarction (OR 0.92, 95% CI 0.44-1.92, p = .83) and permanent pacemaker implantation (PPM) (OR 0.54, 95% CI 0.27-1.07, p = .08) between the two groups. During mid to long-term follow up (6-months to 5-years), there were no significant differences between ViV-TAVR and redo-SAVR for all-cause mortality, cardiovascular mortality and stroke. ViV-TAVR was, however, associated with higher risk of prosthesis-patient mismatch and greater transvalvular pressure gradient post-implantation. CONCLUSION: ViV-TAVR compared to redo-SAVR appears to be associated with significant improvement in short term mortality and major bleeding. For mid to long-term follow up, the outcomes were similar for both groups.

Clinical Characteristics, Management Strategies and Outcomes of Acute Myocardial Infarction Patients With Prior Coronary Artery Bypass Grafting.

OBJECTIVE: To investigate the management strategies, temporal trends, and clinical outcomes of patients with a history of coronary artery bypass graft (CABG) surgery and presenting with acute myocardial infarction (MI). PATIENTS AND METHODS: We undertook a retrospective cohort study using the National Inpatient Sample database from the United States (January 2004-September 2015), identified all inpatient MI admissions (7,250,768 records) and stratified according to history of CABG (group 1, CABG-naive [94%]; group 2, prior CABG [6%]). RESULTS: Patients in group 2 were older, less likely to be female, had more comorbidities, and were more likely to present with non-ST-elevation myocardial infarction compared with group 1. More patients underwent coronary angiography (68% vs 48%) and percutaneous coronary intervention (PCI) (44% vs 26%) in group 1 compared with group 2. Following multivariable logistic regression analyses, the adjusted odd ratio (OR) of in-hospital major adverse cardiovascular and cerebrovascular events (OR, 0.98; 95% CI, 0.95 to 1.005; P=.11), all-cause mortality (OR, 1; 95% CI, 0.98 to 1.04; P=.6) and major bleeding (OR, 0.99; 95% CI, 0.94 to 1.03; P=.54) were similar to group 1. Lower adjusted odds of in-hospital major adverse cardiovascular and cerebrovascular events (OR, 0.64; 95% CI, 0.57 to 0.72; P<.001), all-cause mortality (OR, 0.45; 95% CI, 0.38 to 0.53; P<.001), and acute ischemic stroke (OR, 0.71; 95% CI, 0.59 to 0.86; P<.001) were observed in group 2 patients who underwent PCI compared with those managed medically without any increased risk of major bleeding (OR, 1.08; 95% CI, 0.94 to 1.23; P=.26). CONCLUSIONS: In this national cohort, MI patients with prior-CABG had a higher risk profile, but similar in-hospital adverse outcomes compared with CABG-naive patients. Prior-CABG patients who received PCI had better in-hospital clinical outcomes compared to those who received medical management.

Complexity of Antiplatelet Therapy in Coronary Artery Disease Patients.

Patients with coronary artery disease (CAD) presenting with acute coronary syndrome or undergoing coronary stenting are indicated to treatment with dual antiplatelet therapy (DAPT) combining aspirin with a P2Y12 receptor inhibitor. The management of patients with CAD who present with a complex clinical profile due to multiple comorbidities, and/or undergoing complex interventional procedures, remains challenging as a high risk for both ischemic and bleeding events is often present; hence, the risk-benefit balance on the optimal DAPT duration is difficult to evaluate. The complexity of antiplatelet therapy in CAD patients is due to the fact that this complexity embraces several aspects: the coronary anatomy, the number of vascular districts at risk for atherothrombosis, and patient comorbidities, including global frailty. Recent randomized and epidemiological studies have highlighted subgroups that could benefit from prolonged antithrombotic treatment, as well as frail patients, who may be better suited to a shorter course of therapy. We provide an overview of the current knowledge regarding treatment with DAPT, along with suggestions on its management.

Acute Myocardial Infarction in Autoimmune Rheumatologic Disease: A Nationwide Analysis of Clinical Outcomes and Predictors of Management Strategy.

OBJECTIVES: To examine national-level differences in management strategies and outcomes in patients with autoimmune rheumatic disease (AIRD) with acute myocardial infarction (AMI) from 2004 through 2014. METHODS: All AMI hospitalizations were analyzed from the National Inpatient Sample, stratified according to AIRD diagnosis into 4 groups: no AIRD, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and systemic sclerosis (SSC). The associations between AIRD subtypes and (1) receipt of coronary angiography and percutaneous coronary intervention (PCI) and (2) clinical outcomes were examined compared with patients without AIRD. RESULTS: Of 6,747,797 AMI hospitalizations, 109,983 patients (1.6%) had an AIRD diagnosis (RA: 1.3%, SLE: 0.3%, and SSC: 0.1%). The prevalence of RA rose from 1.0% (2004) to 1.5% (2014), and SLE and SSC remained stable. Patients with SLE were less likely to receive invasive management (odds ratio [OR] [95% CI]: coronary angiography-0.87; 0.84 to 0.91; PCI-0.93; 0.90 to 0.96), whereas no statistically significant differences were found in the RA and SSC groups. Subsequently, the ORs (95% CIs) of mortality (1.15; 1.07 to 1.23) and bleeding (1.24; 1.16 to 1.31) were increased in patients with SLE; SSC was associated with increased ORs (95% CIs) of major adverse cardiovascular and cerebrovascular events (1.52; 1.38 to 1.68) and mortality (1.81; 1.62 to 2.02) but not bleeding or stroke; the RA group was at no increased risk for any complication. CONCLUSION: In a nationwide cohort of AMI hospitalizations we found lower use of invasive management in patients with SLE and worse outcomes after AMI in patients with SLE and SSC compared with those without AIRD.

Percutaneous Intervention or Bypass Graft for Left Main Coronary Artery Disease? A Systematic Review and Meta-Analysis.

BACKGROUND: The safety and efficacy of percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) for stable left main coronary artery disease (LMCAD) remains controversial. METHODS: Digital databases were searched to compare the major adverse cardiovascular and cerebrovascular events (MACCE) and its components. A random effect model was used to compute an unadjusted odds ratio (OR). RESULTS: A total of 43 studies (37 observational and 6 RCTs) consisting of 29,187 patients (PCI 13,709 and CABG 15,478) were identified. The 30-day rate of MACCE (OR, 0.56; 95% CI, 0.42-0.76; p = 0.0002) and all-cause mortality (OR, 0.52; 95% CI, 0.30-0.91; p = 0.02) was significantly lower in the PCI group. There was no significant difference in the rate of myocardial infarction (MI) (p = 0.17) and revascularization (p = 0.12). At 5 years, CABG was favored due to a significantly lower rate of MACCE (OR, 1.67; 95% CI, 1.18-2.36; p = <0.04), MI (OR, 1.67; 95% CI, 1.35-2.06; p = <0.00001), and revascularization (OR, 2.80; 95% CI, 2.18-3.60; p = <0.00001), respectively. PCI was associated with a lower overall rate of a stroke, while the risk of all-cause mortality was not significantly different between the two groups at 1- (p = 0.75), 5- (p = 0.72), and 10-years (p = 0.20). The Kaplan-Meier curve reconstruction revealed substantial variations over time; the 5-year incidence of MACCE was 38% with CABG, significantly lower than 45% with PCI (p = <0.00001). CONCLUSION: PCI might offer early safety advantages, while CABG provides greater durability in terms of lower long-term risk of ischemic events. There appears to be an equivalent risk for all-cause mortality.
