Impact of Society Guidelines on Trends in Use of Newer P2Y12 Inhibitors for Patients With Acute Coronary Syndromes Undergoing Percutaneous Coronary Intervention.

BACKGROUND: Over the past decade, major society guidelines have recommended the use of newer P2Y12 inhibitors over clopidogrel for those undergoing percutaneous coronary intervention for acute coronary syndrome. It is unclear what impact these recommendations had on clinical practice. METHODS AND RESULTS: All percutaneous coronary intervention procedures (n=534 210) for acute coronary syndrome in England and Wales (April 1, 2010, to March 31, 2022) were retrospectively analyzed, stratified by choice of preprocedural P2Y12 inhibitor (clopidogrel, ticagrelor, and prasugrel). Multivariable logistic regression models were used to examine odds ratios of receipt of ticagrelor and prasugrel (versus clopidogrel) over time, and predictors of their receipt. Overall, there was a significant increase in receipt of newer P2Y12 inhibitors from 2010 to 2020 (2022 versus 2010: ticagrelor odds ratio, 8.12 [95% CI, 7.67-8.60]; prasugrel odds ratio, 6.14 [95% CI, 5.53-6.81]), more so in ST-segment-elevation myocardial infarction than non-ST-segment-elevation acute coronary syndrome indication. The most significant increase in odds of receipt of prasugrel was observed between 2020 and 2022 (P<0.001), following a decline/plateau in its use in earlier years (2011-2019). In contrast, the odds of receipt of ticagrelor significantly increased in earlier years (2012-2017, Ptrend<0.001), after which the trend was stable (Ptrend=0.093). CONCLUSIONS: Over a 13-year-period, there has been a significant increase in use of newer P2Y12 inhibitors, although uptake of prasugrel use remained significantly lower than ticagrelor. Earlier society guidelines (pre-2017) were associated with the highest rates of ticagrelor use for non-ST-segment-elevation acute coronary syndrome and ST-segment-elevation myocardial infarction cases while the ISAR-REACT 5 (Prospective, Randomized Trial of Ticagrelor Versus Prasugrel in Patients With Acute Coronary Syndrome) trial and later society guidelines were associated with higher prasugrel use, mainly for ST-segment-elevation myocardial infarction indication.

Socioeconomic and Ethnic Disparities in the Process of Care and Outcomes Among Cancer Patients With Acute Coronary Syndrome.

Cancer and acute coronary syndrome (ACS) are the leading causes of morbidity and mortality globally, with many shared risk factors. There are several challenges to the management of patients with cancer presenting with ACS, owing to their higher baseline risk profile, the complexities of their cancer-related therapies and prognosis, and their higher risk of adverse outcomes after ACS. Although previous studies have demonstrated disparities in the care of both cancer and ACS among patients from ethnic minorities and socioeconomic deprivation, there is limited evidence around the magnitude of such disparities specifically in cancer patients presenting with ACS. This review summarises the current literature on differences in prevalence and management of ACS among patients with cancer from ethnic minorities and socioeconomically deprived backgrounds, as well as the gaps in evidence around the care of this high-risk population and potential solutions.

The clinical characteristics, managements, and outcomes of acute myocardial infarction in osteoarthritis patients; a cross-sectional analysis of 6.5 million patients.

OBJECTIVES: The prevalence of osteoarthritis (OA) and cardiovascular disease are increasing and both conditions share similar risk factors. We investigated the association between OA and receipt of invasive managements and clinical outcomes in patients with acute myocardial infarction (AMI). METHODS: Using the National Inpatient Sample, adjusted binary logistic regression determined the association between OA and each outcome variable. RESULTS: Of 6,561,940 AMI hospitalizations, 6.3% had OA. OA patients were older and more likely to be female. OA was associated with a decreased odds of coronary angiography (adjusted odds ratio 0.91; 95% confidence interval 0.90, 0.92), PCI (0.87; 0.87, 0.88), and coronary artery bypass grafting (0.98; 0.97, 1.00). OA was associated with a decreased odds of adverse outcomes (in-hospital mortality: 0.68; 0.67, 0.69; major acute cardiovascular and cerebrovascular events: 0.71; 0.70, 0.72; all-cause bleeding: 0.76; 0.74, 0.77; and stroke/TIA: 0.84; 0.82, 0.87). CONCLUSIONS: This study of a representative sample of the US population highlights that OA patients are less likely to be offered invasive interventions following AMI. OA was also associated with better outcomes post-AMI, possibly attributed to a misclassification bias where unwell patients with OA were less likely to receive an OA code because codes for serious illness took precedence.

Intracoronary imaging guided percutaneous coronary intervention outcomes among individuals with cardiogenic shock.

BACKGROUND: Limited data exist around the utility of intracoronary imaging (ICI) during percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS) and cardiogenic shock (CS), who are inherently at a high risk of stent thrombosis (ST). METHODS: All PCI procedures for ACS patients with CS in England and Wales between 2014 and 2020 were retrospectively analysed, stratified into two groups: ICI and angiography-guided groups. Multivariable logistic regression analyses were performed to examine odds ratios (OR) of in-hospital outcomes, including major adverse cardiovascular and cerebrovascular events (MACCE; composite of all-cause mortality, acute stroke/transient ischaemic attack (TIA), and reinfarction) and major bleeding, in the ICI-guided group compared with angiography-guided PCI. RESULTS: Of 15,738 PCI procedures, 1240(7.9%) were ICI-guided. The rate of ICI use amongst those with CS more than doubled from 2014 (5.7%) to 2020 (13.3%). The ICI-guided group were predominantly younger, males, with a higher proportion of non-ST-elevation ACS and ST. MACCE was significantly lower in the ICI-guided group compared with the angiography-guided group (crude: 29.8% vs. 38.2%, adjusted odds ratio (OR) 0.65 95% confidence interval [CI] 0.56-0.76), driven by lower all-cause mortality (28.6% vs. 37.0%, OR 0.65 95% CI 0.55-0.75). There were no differences in other secondary outcomes between groups. CONCLUSION: ICI use among CS patients has more than doubled over 6 years but remains significantly under-utilized, with less than 1-in-6 patients in receipt of ICI-guided PCI by 2020. ICI-guided PCI is associated with prognostic benefits in CS patients and should be more frequently utilized to increase their long-term survival.

In-hospital outcomes of acute ischaemic stroke patients with atrial septal defect. A national inpatient sample study.

BACKGROUND AND AIMS: Atrial septal defects (ASD) are a well-recognised risk factor for acute ischaemic stroke (AIS). We aimed to delineate the relationship between ASD and in-hospital AIS outcomes (mortality, severe stroke (National Institutes of Health Stroke Scale (NIHSS) > 15), prolonged hospitalisation > 4 days and routine home discharge) in contemporary practice using data from the United States National Inpatient Sample. METHODS: NIS admissions with a primary diagnosis of AIS between 2016-2018 were extracted. The NIHSS variable had 75% missing data, which were imputed using multiple imputations by chained equations. The relationship between ASD and the main outcomes was modelled using multivariable logistic regressions, adjusting for age, sex, comorbidities, stroke severity and revascularisation therapies. RESULTS: 245,859 records representative of 1,229,295 AIS admissions were included, 35,840 (2.91%) of whom had ASD. ASD patients were younger (median age 63 years versus 72 years) and less likely to have traditional cardiovascular risk factors than their counterparts without ASD. ASD was independently associated with 58% lower odds of in-hospital mortality (hazard ratio (95% confidence interval) = 0.42 (0.33-0.54)), 18% lower odds of severe stroke (0.82 (0.71-0.94)), 20% higher odds of routine home discharge (1.20 (1.14-1.28)) and 28% higher odds of prolonged hospitalisation (1.28 (1.21-1.35)). CONCLUSIONS: ASD was associated with better in-hospital outcomes, which were likely driven by younger age, lower prevalence of traditional cardiovascular risk factors, and lower stroke severity. Further research is warranted to clarify the ASD anatomical characteristics which are most strongly associated with these associations.

Intracoronary imaging in PCI for acute coronary syndrome: Insights from British Cardiovascular Intervention Society registry.

BACKGROUND: While previous studies have demonstrated the superiority of ICI-guided PCI over an angiography-based approach, there are limited data on all-comer ACS patients. This study aimed to identify the characteristics and in-hospital outcomes of patients undergoing intracoronary imaging (ICI) guided percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). METHODS: All patient undergoing PCI for ACS in England and Wales between 2006 and 2019 were retrospectively analyzed and stratified according to ICI utilization. The outcomes assessed were in-hospital all-cause mortality and major adverse cardiovascular and cerebrovascular events (MACCE) using multivariable logistic regression models. RESULTS: 598,921 patients underwent PCI for ACS, of which 41,716 (7.0 %) had ICI which was predominantly driven by IVUS use (5.6 %). ICI use steadily increased from 1.4 % in 2006 to 13.5 % in 2019. Adjusted odds of mortality (OR 0.69, 95%CI 0.58-0.83) and MACCE (OR 0.77, 95%CI 0.73-0.83) were significantly lower in the ICI group. The association between ICI and improved outcomes varied according to vessel treated with both left main stem (LMS) and LMS/left anterior descending (LAD) PCI associated with significantly lower odds of mortality (OR 0.34, 95%CI 0.27-0.44, OR 0.51 95%CI 0.45-0.56) and MACCE (OR 0.44 95%CI 0.35-0.54, OR 0.67 95%CI 0.62-0.72) respectively. CONCLUSIONS: Although ICI use has steadily increased, less than one in seven patients underwent ICI-guided PCI. The association between ICI use and improved in-hospital outcomes was mainly observed in PCI procedures involving LMS and LAD.

Race and sex disparities in acute outcomes of patients with acute ischemic stroke and diabetes mellitus. A national inpatient sample study.

BACKGROUND: Diabetes Mellitus (DM) disproportionately affects racial minority groups and is a well-established risk factor for ischemic stroke and worse stroke outcomes. Whether racial disparities exist in acute outcomes of patients presenting with Acute Ischemic Stroke (AIS) and comorbid DM, including potential differences in the administration of evidence-based reperfusion therapy, remains unclear. We aimed to assess whether racial and sex differences exist in the acute outcomes and treatment of patients with DM presenting with AIS. METHODS: January 2016-December 2018 AIS admissions with diabetes were extracted from the US National Inpatient Sample (NIS). Multivariable logistic regressions assessed the association between race, sex, and differences in in-hospital outcomes (mortality, hospitalisation >4 days, routine discharge, and stroke severity). Further models assessed the relationship between race, sex, and receipt of thrombolysis and thrombectomy. All models were adjusted for relevant confounders, including comorbidities and stroke severity. RESULTS: 92,404 records representative of 462,020 admissions were extracted. Median (IQR) age was 72 (61-79), with 49 % women, 64 % White, 23 % African American, and 10 % Hispanic patients. African Americans had lower odds of in-hospital mortality compared to Whites (adjusted odds ratio; 99 % confidence interval=0.72;0.61-0.86), but were more likely to have prolonged hospitalisation (1.46;1.39-1.54), be discharged to locations other than home (0.78;0.74-0.82) and have moderate/severe stroke (1.17;1.08-1.27). Additionally, African American (0.76;0.62-0.93) and Hispanic patients (0.66;0.50-0.89) had lower odds of receiving thrombectomy. Compared to men, women had increased odds of in-hospital mortality (1.15;1.01-1.32). CONCLUSIONS: Racial and sex disparities exist in both evidence-based reperfusion therapy and in-hospital outcomes amongst patients with AIS and diabetes. Further measures are needed to address these disparities and reduce the excess risk of adverse outcomes among women and African American patients.

Assessment of Paclitaxel Drug-Coated Balloon Only Angioplasty in STEMI.

BACKGROUND: Primary percutaneous coronary intervention (pPCI) with drug-eluting stents (DES) has emerged as the standard of care, but stent-related events have persisted. Drug-coated balloon (DCB)-only angioplasty is an emerging technology, although it is not fully evaluated compared with DES in the context of pPCI. OBJECTIVES: The aim of this study was to investigate the safety of DCB-only angioplasty compared with second-generation DES in pPCI. METHODS: All-cause mortality and net adverse cardiac events (cardiovascular mortality, acute coronary syndrome, ischemic stroke or transient ischemic attack, major bleeding, and unplanned target lesion revascularization [TLR]) were compared among all patients treated with DCBs only or with second-generation DES only for first presentation of ST-segment elevation myocardial infarction (STEMI) due to de novo disease between January 1, 2016, and November 15, 2019. Patients treated with both DCBs and DES were excluded. Data were analyzed using Cox regression models, Kaplan-Meier estimator plots and propensity score matching. RESULTS: Among 1,139 patients with STEMI due to de novo disease, 452 were treated with DCBs and 687 with DES. After a median follow-up period of >3 years, all-cause mortality was 49 of 452 and 62 of 687 in the DCB and DES groups, respectively (P = 0.18). On multivariable Cox regression analysis, there was no difference in mortality between DCBs and DES in the full and propensity score-matched cohorts. Age, frailty risk, history of heart failure, and family history of ischemic heart disease remained significant independent predictors of mortality. There was no difference in any of the secondary endpoints, including unplanned TLR. CONCLUSIONS: DCB-only angioplasty appears safe compared with DES for STEMI in terms of all-cause mortality and all net adverse cardiac events, including unplanned TLR. DCB may be an efficacious and safe alternative to DES in selected patient groups. (Drug Coated Balloon Only vs Drug Eluting Stent Angioplasty; NCT04482972).

Association between cancer, CHA2DS2VASc risk, and in-hospital ischaemic stroke in patients hospitalized for atrial fibrillation.

BACKGROUND: Atrial fibrillation (AF) is commonly encountered in cancer patients. We investigated the CHA2DS2VASc score, and its association with in-hospital ischaemic stroke in patients with cancer who were hospitalized for AF. METHODS AND RESULTS: Using the United States National Inpatient Sample, all hospitalizations with principal diagnosis of AF between October 2015 and December 2018 were stratified by cancer diagnosis, type, and CHA2DS2VASc risk categories (low risk, low-moderate risk, moderate-high risk). In-hospital ischaemic stroke and its association with the CHA2DS2VASc risk score was assessed across the groups using hierarchical multivariable logistic regression with adjusted odds ratios (aOR) and 95% confidence intervals (95% CI). Discrimination of CHA2DS2VASc score for in-hospital ischaemic stroke was evaluated with Receiver Operating Characteristic and Area Under the Curve (AUC). Among 1 341 870 included hospitalizations, 71 965 (5.4%) had comorbid cancer. Cancer patients had a higher proportion of moderate-high CHA2DS2VASc risk compared with their non-cancer counterparts (86.5% vs. 82.3%, P < 0.001). Compared with their low CHA2DS2VASc risk counterparts, cancer patients in low-moderate and moderate-high risk scores had similar odds of developing stroke (aOR 1.28 95% CI 0.22-7.63 and aOR 1.78 95% CI 0.41-7.66, respectively). The CHA2DS2VASc risk score had poor discrimination for ischaemic stroke in the cancer group (AUC 0.538 95% CI 0.477-0.598). CONCLUSION: Cancer patients with AF have high CHA2DS2VASc risk. Discrimination of CHA2DS2VASc for ischaemic stroke is lower in cancer than non-cancer patients, and CHA2DS2VASc may not be adequate in determining ischaemic risk in cancer population.

Sex-Specific Outcomes of Acute Stroke in Patients with Systemic Lupus Erythematosus: A National Inpatient Sample Study.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disorder associated with increased stroke risk. Its association with stroke outcomes remains poorly understood. In this study, we aimed to compare the sex-specific SLE-associated acute stroke outcomes. Methods: Stroke hospitalisations between 2015 and 2018 from the National Inpatient Sample were analysed. The associations between SLE and outcomes (inpatient mortality, length-of-stay > 4 days and routine discharge) were examined using multivariable logistic regressions, stratifying by sex and adjusting for age, race, stroke type, revascularisation, hospital characteristics and comorbidities. Results: A total of 316,531 records representing 1,581,430 hospitalisations were included. Median (interquartile range) age was 71 (60−82) years. There were 940 (0.06%) males and 6110 (0.39%) females with SLE. There were no associations between SLE and mortality amongst either females (odds ratio (95% confidence interval) = 1.11 (0.84−1.48)) or males (0.81 (0.34−1.94)). Nevertheless, SLE was associated with prolonged hospitalisation (1.17 (1.03−1.32)) and lower odds of routine discharge (0.82 (0.72−0.94)) amongst females. There were no associations between SLE and other adverse outcomes amongst males. Conclusions: The association between SLE and acute stroke outcomes was influenced by sex. While SLE was not associated with mortality in either sex, females with SLE had higher odds of prolonged hospitalisation and lower odds of routine home discharge compared to patients without SLE, while males did not exhibit this increased risk.

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.

Paclitaxel drug-coated balloon-only angioplasty for de novo coronary artery disease in elective clinical practice.

OBJECTIVE: We aimed to investigate the safety of drug-coated balloon (DCB)-only angioplasty compared to drug-eluting stent (DES), as part of routine clinical practice. BACKGROUND: The recent BASKETSMALL2 trial demonstrated the safety and efficacy of DCB angioplasty for de novo small vessel disease. Registry data have also demonstrated that DCB angioplasty is safe; however, most of these studies are limited due to long recruitment time and a small number of patients with DCB compared to DES. Therefore, it is unclear if DCB-only strategy is safe to incorporate in routine elective clinical practice. METHODS: We compared all-cause mortality and major cardiovascular endpoints (MACE), including unplanned target lesion revascularisation (TLR) of all patients treated with DCB or DES for first presentation of stable angina due to de novo coronary artery disease between 1st January 2015 and 15th November 2019. Data were analysed with Cox regression models and cumulative hazard plots. RESULTS: We present 1237 patients; 544 treated with DCB and 693 treated with DES for de novo, mainly large-vessel coronary artery disease. On multivariable Cox regression analysis, only age and frailty remained significant adverse predictors of all-cause mortality. Univariable, cumulative hazard plots showed no difference between DCB and DES for either all-cause mortality or any of the major cardiovascular endpoints, including unplanned TLR. The results remained unchanged following propensity score-matched analysis. CONCLUSION: DCB-only angioplasty, for stable angina and predominantly large vessels, is safe compared to DES as part of routine clinical practice, in terms of all-cause mortality and MACE, including unplanned TLR.

Temporal trends of hospitalizations, comorbidity burden and in-hospital outcomes in patients admitted with asthma in the United States: Population-based study.

BACKGROUND: Asthma is a prevalent chronic respiratory condition and remains a common cause for hospitalization. However, contemporary data on asthma hospitalization rates, comorbidity burden, and in-hospital outcomes are lacking. METHODS: Survey-weighted analysis of hospitalization records with a primary diagnosis of asthma using data from the US National (Nationwide) Inpatient Sample between 2004 and 2017. Outcomes were number of hospitalizations per 100,000 population and in-hospital outcomes including receipt of ventilation, length of stay, and hospital costs. Patient and admission characteristics and comorbidity burden were examined over time. Multivariable logistic and linear regression models were fitted for over-time risks of the outcomes. RESULTS: Among 3,098,863 asthma admissions between 2004 and 2017, mean (±SD) age was 29 (±25), 57% females, 36% White, 40% had Medicaid as primary payer. During 2004-2017, asthma hospitalizations declined from 89 to 56 per 100,000 population; length of stay remained overall stable; median (interquartile range IQR) inflation-adjusted hospital costs doubled from $8,446 (9,227) in 2004 to $17,756 (19,434) in 2017. Common comorbidities in patients admitted with asthma were hypertension and diabetes in adults, but gastroesophageal reflux disease, obstructive sleep apnoea, anemia, and obesity in children. Over time, the prevalence of mental illness increased by >50%. Severe asthma (IRR, 2.48; 95%CI: 2.27-2.72) and psychoses (IRR, 1.10; 1.05-1.14) were predictors of prolonged hospitalization. Asian/Pacific Islanders were more likely to receive ventilation (OR: 2.35; 1.73-3.20) than White patients. Hospital costs were significantly higher in females and adults with hypertension (coefficient, 1405.2; 283.1-2527.4) or psychoses (coefficient, 1978.4; 674.9-3282.0). CONCLUSIONS: US asthma hospitalization rates fluctuated in earlier years but declined over time, which may reflect improvements in community care and declining asthma prevalence. Comorbidity burden, including mental illness, increased over time and is associated with in-hospital outcomes. This highlights the changing landscape of asthma admissions which may inform redesigning services to support pre-hospitalization asthma care and help further reduce admissions, particularly among patients with multimorbidity.

Palliative Care Utilization Among Hospitalized Patients With Common Chronic Conditions in the United States.

Objective: Limited data exist around the receipt of palliative care (PC) in patients hospitalized with common chronic conditions. We studied the independent predictors, temporal trends in rates of PC utilization in patients hospitalized with acute exacerbation of common chronic diseases. Methods: Population-based cohort study of all hospitalizations with an acute exacerbation of heart disease (HD), cerebrovascular accident (CVA), cancer (CA), and chronic lower respiratory disease (CLRD). Patients aged ≥18 years or older between January 1, 2004, and December 31, 2017, referred for inpatient PC were extracted from the National Inpatient Sample. Poisson regression analyses were used to estimate temporal trends. Results: Between 2004 and 2017, of 91,877,531 hospitalizations, 55.2%, 13.9%, 17.2%, and 13.8% hospitalizations were related to HD, CVA, CA, and CLRD, respectively. There was a temporal increase in the uptake of PC across all disease groups. Age-adjusted estimated rates of PC per 100,000 hospitalizations/year were highest for CA (2308 (95% CI 2249-2366) to 10,794 (95% CI 10,652-10,936)), whereas the CLRD cohort had the lowest rates of PC referrals (255 (95% CI 231-278) to 1882 (95% CI 1821-1943)) between 2004 and 2017, respectively. In the subgroup analysis of patients who died during hospitalization, the CVA group had the highest uptake of PC per 100,000 hospitalizations/year (4979 (95% CI 4918-5040)) followed by CA (4241 (95% CI 4189-4292)), HD (3250 (95% CI 3211-3289)) and CLRD (3248 (95% CI 3162-3405)). Conclusion: PC service utilization is increasing but remains disparate, particularly in patients that die during hospital admission from common chronic conditions. These findings highlight the need to develop a multidisciplinary, patient-centered approach to improve access to PC services in these patients.

Impact of Intracoronary Imaging-Guided Percutaneous Coronary Intervention on Procedural Outcomes Among Complex Patient Groups.

Background Intracoronary imaging (ICI) has been shown to improve survival after percutaneous coronary intervention (PCI). Whether this prognostic benefit is sustained across different indications remains unclear. Methods and Results All PCI procedures performed in England and Wales between April, 2014 and March 31, 2020, were retrospectively analyzed. The association between ICI use and in-hospital major acute cardiovascular and cerebrovascular events; composite of all-cause mortality, stroke, and reinfarction and mortality was examined using multivariable logistic regression analysis for different imaging-recommended indications as set by European Association for Percutaneous Cardiovascular Interventions consensus. Of 555 398 PCI procedures, 10.8% (n=59 752) were ICI-guided. ICI use doubled between 2014 (7.8%) and 2020 (17.5%) and was highest in left main PCI (41.2%) and lowest in acute coronary syndrome (9%). Only specific European Association for Percutaneous Cardiovascular Interventions imaging-recommended indications were associated with reduced major acute cardiovascular and cerebrovascular events and mortality, including left main PCI (odds ratio [OR], 0.45 [95% CI, 0.39-0.52] and 0.41 [95% CI, 0.35-0.48], respectively), acute coronary syndrome (OR, 0.76 [95% CI, 0.70-0.82] and 0.70 [95% CI, 0.63-0.77]), and stent length >60 mm (OR, 0.75 [95% CI, 0.59-0.94] and 0.72 [95% CI, 0.54-0.95]). Stent thrombosis and renal failure were associated with lower mortality (OR, 0.69 [95% CI, 0.52-0.91]) and major acute cardiovascular and cerebrovascular events (OR, 0.77 [95% CI, 0.60-0.99]), respectively. Conclusions ICI use has more than doubled over a 7-year period at a national level but remains low, with <1 in 5 procedures performed under ICI guidance. In-hospital survival was better with ICI-guided than angiography-guided PCI, albeit only for specific indications.

Clinical Outcomes of Percutaneous Coronary Intervention for Bifurcation Lesions According to Medina Classification.

Background Coronary bifurcation lesions (CBLs) are frequently encountered in clinical practice and are associated with worse outcomes after percutaneous coronary intervention. However, there are limited data around the prognostic impact of different CBL distributions. Methods and Results All CBL percutaneous coronary intervention procedures from the prospective e-Ultimaster (Prospective, Single-Arm, Multi Centre Observations Ultimaster Des Registry) multicenter international registry were analyzed according to CBL distribution as defined by the Medina classification. Cox proportional hazards models were used to compare the hazard ratio (HR) of the primary outcome, 1-year target lesion failure (composite of cardiac death, target vessel-related myocardial infarction, and clinically driven target lesion revascularization), and its individual components between Medina subtypes using Medina 1.0.0 as the reference category. A total of 4003 CBL procedures were included. The most prevalent Medina subtypes were 1.1.1 (35.5%) and 1.1.0 (26.8%), whereas the least prevalent was 0.0.1 (3.5%). Overall, there were no significant differences in patient and procedural characteristics among Medina subtypes. Only Medina 1.1.1 and 0.0.1 subtypes were associated with increased target lesion failure (HR, 2.6 [95% CI, 1.3-5.5] and HR, 4.0 [95% CI, 1.6-9.0], respectively) at 1 year, compared with Medina 1.0.0, prompted by clinically driven target lesion revascularization (HR, 3.1 [95% CI, 1.1-8.6] and HR, 4.6 [95% CI, 1.3-16.0], respectively) as well as cardiac death in Medina 0.0.1 (HR, 4.7 [95% CI, 1.0-21.6]). No differences in secondary outcomes were observed between Medina subtypes. Conclusions In a large multicenter registry analysis of coronary bifurcation percutaneous coronary intervention procedures, we demonstrate prognostic differences in 1-year outcomes between different CBL distributions, with Medina 1.1.1 and 0.0.1 subtypes associated with an increased risk of target lesion failure.

Influence of the Danish Co-morbidity Index Score on the Treatment and Outcomes of 2.5 Million Patients Admitted With Acute Myocardial Infarction in the United States.

This study aimed to determine the association between the Danish Co-morbidity Index for Acute Myocardial Infarction (DANCAMI) and restricted DANCAMI (rDANCAMI) scores and clinical outcomes in patients hospitalized with AMI. Using the National Inpatient Sample, all AMI hospitalizations were stratified into four groups based on their DANCAMI and rDANCAMI score (0; 1 to 3; 4 to 5; ≥6). The primary outcome was all-cause mortality, whereas secondary outcomes were major adverse cardiovascular/cerebrovascular events, major bleeding, ischemic stroke, and receipt of coronary angiography or percutaneous coronary intervention. Multivariate logistic regression was used to determine adjusted odds ratios (aOR) with 95% confidence intervals (95% CIs). Patients with DANCAMI risk score ≥6 were more likely to suffer mortality (aOR 2.30, 95% CI 2.24 to 2.37) and bleeding (aOR 5.85, 95% CI 5.52 to 6.21) and were less likely to receive coronary angiography (aOR 0.34, 95% CI 0.33 to 0.34) and percutaneous coronary intervention (aOR 0.29, 95% CI 0.28 to 0.29) compared with patients with DANCAMI score of 0. Similar results were observed for the rDANCAMI score. In conclusion, increased DANCAMI and rDANCAMI scores were associated with worse in-hospital outcomes in patients with AMI and lower odds of invasive management. The use of co-morbidity scores identifies patients at high risk of adverse outcomes and highlights disparities in care.

Emergency department cardiovascular disease encounters and associated mortality in patients with cancer: A study of 20.6 million records from the USA.

BACKGROUND: there is limited data on Emergency department (ED) cardiovascular disease (CVD) presentations and outcomes amongst cancer patients. OBJECTIVES: The present study aimed to describe the clinical characteristics, prevalence, and clinical outcomes of the most common cardiovascular ED admissions in patients with cancer. METHODS: All ED encounters with a primary CVD diagnosis from the US Nationwide Emergency Department Sample between January 2016 to December 2018 were stratified by cancer type as well as metastatic status. Multivariable logistic regression was performed to determine the adjusted odds ratios of in-hospital mortality in different groups. RESULTS: From a total of 20,737,247 ED encounters with a primary CVD diagnosis, cancer was present in 3.4%. In patients with cancer the most common CVDs were DVT/PE (20%), hypertensive heart or kidney disease (14.7%), and AF/flutter (11.2%). The distribution of CVDs varied by cancer type, with AF/flutter most common in patients with lung cancer, AMI most common in patients with prostate cancer, heart failure most common in those with haematological malignancies, and patients with colorectal cancer having the greatest frequency of DVT/PE. Cancer status was independently associated with significantly higher risk of mortality in almost all CVD categories, consistent across all the cancer types, amongst which lung cancer patients had the highest risk of mortality across all CVD categories, except intracranial haemorrhage and hypertensive crisis. CONCLUSIONS: Cardiovascular presentations to the ED varied by cancer subtype. Across all cancer subtypes, patients presenting with cardiovascular presentations carried a significantly increased risk of mortality compared to patients with no cancer.

Relation of Extracardiac Vascular Disease and Outcomes in Patients With Diabetes (1.1 Million) Hospitalized for Acute Myocardial Infarction.

The association between vascular disease and outcomes of patients with acute myocardial infarction (AMI) has not been well-defined in the diabetes mellitus (DM) population. All patients with DM presenting with AMI between October 2015 and December 2018 in the National Inpatient Sample database were stratified by number and site of extracardiac vascular comorbidity (cerebrovascular [CVD], renovascular, neural, retinal and peripheral [PAD] diseases). Multivariable logistic regression was used to determine the adjusted odds ratios (aORs) of in-hospital adverse outcomes and procedures. Of 1,116,670 patients with DM who were hospitalized for AMI, 366,165 had ≥1 extracardiac vascular comorbidity (32.8%). Patients with vascular disease had an increased aOR for mortality (aOR 1.05, 95% confidence interval [CI] 1.04 to 1.07), major adverse cardiovascular and cerebrovascular events (MACCEs) (aOR 1.19, 95% CI 1.18 to 1.21), stroke (aOR 1.72, 95% CI 1.68 to 1.76), and major bleeding (aOR 1.11, 95% CI 1.09 to 1.13) and had lower odds of receiving coronary angiography (CA) (aOR 0.90, 95% CI 0.90 to 0.91) and percutaneous coronary intervention (PCI) (aOR 0.82, 95% CI 0.82 to 0.83) than patients without extracardiac vascular disease. Patients with PAD had the highest odds of mortality (aOR 1.29, 95% CI 1.27 to 1.32), whereas patients with CVD had the greatest odds of MACCEs, stroke, and major bleeding (aOR 1.82, 95% CI 1.78 to 1.87, aOR 4.25, 95% CI 4.10 to 4.40, and aOR 1.51, 95% CI 1.45 to 1.57, respectively). Patients with DM presenting with AMI and concomitant extracardiac vascular disease were more likely to develop clinical outcomes and less likely to undergo CA or PCI. Patients with PAD had the highest risk of mortality, whereas patients with CVD had the greatest risk of MACCEs, stroke, and major bleeding.
