Complex High-Risk Percutaneous Coronary Intervention Types, Trends, and Outcomes in Nonsurgical Centres. Can J Cardiol 2024:S0828-282X(24)00010-2. [PMID: 38215968 DOI: 10.1016/j.cjca.2024.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 12/20/2023] [Accepted: 01/01/2024] [Indexed: 01/14/2024] Open
Abstract
BACKGROUND Limited data are available on complex high-risk percutaneous coronary intervention (CHiP) trends and outcomes in nonsurgical centres (NSCs), particularly in health care systems where most centres are NSCs. METHODS Using data from a national registry, we studied the characteristics and outcomes of CHiP procedures performed for stable angina from 2006 to 2017 according to the presence or absence of on-site surgical cover. Multivariate regression analyses and propensity score matching were used to determine risks for in-hospital death, major bleeding, and major cardiovascular or cerebral events (MACCE). RESULTS Out of 134,730 CHiP procedures, 42,433 (31.5%) were performed in NSCs, increasing from 12.5% in 2006 to 42% in 2017. Compared with surgical centres (SCs), patients who had a CHiP procedure undertaken in NSCs were, on average, 2.4 years older and had a greater prevalence of cardiovascular risks. Common CHiP procedures performed in NSCs included poor left ventricular function (41.6%), chronic renal failure (38.8%), and chronic total occlusion percutaneous coronary intervention (31.1%). NSC-based CHiP is associated with lower odds of mortality (adjusted odds ratio [aOR] 0.7, 95% confidence interval [CI] 0.5-0.8) and major bleeding (aOR 0.7, 95% CI 0.6-0.8). In both groups, MACCE odds were similar (aOR 1.0, 95% CI 0.9-1.1). CONCLUSIONS CHiP numbers have steadily increased in NSCs. NSC patients were older and had a higher prevalence of cardiovascular risks than SC patients. Mortality and major bleeding odds were significantly lower in those cases undertaken in NSCs, although MACCE odds were not different between the groups.

Complex high-risk percutaneous coronary intervention types, trends, and outcomes according to vascular access site. Catheter Cardiovasc Interv 2023; 102:803-813. [PMID: 37750228 DOI: 10.1002/ccd.30846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 05/15/2023] [Accepted: 09/13/2023] [Indexed: 09/27/2023]
Abstract
BACKGROUND Radial access is associated with improved outcomes following percutaneous coronary intervention (PCI); however, its role in complex, high-risk percutaneous coronary intervention (CHiP) remains poorly studied. METHODS We studied retrospectively all registered patients's records from the British Cardiovascular Intervention Society dataset and compared the baseline characteristics, trends and outcomes of CHiP procedures performed electively between January 2006 and December 2017 according to the access site. RESULTS Out of 137,785 CHiP procedures, 61,825 (44.9%) were undertaken via transradial access (TRA). TRA use increased over time (14.6% in 2006 to 67% in 2017). The TRA patients were older, with a greater prevalence of previous stroke, hypertension, peripheral vascular disease, and smokers. TRA was used more frequently in most CHiP procedures (elderly (51.6%), chronic renal failure (52.6%), poor left ventricular (LV) function (47.6%), left main PCI (48.0%), treatment for severe vascular calcification (50.3%); although transfemoral access (TFA) was used more commonly in those with prior history of coronary artery bypass graft surgery, and PCI to a chronic total occlusion and LV support patients. Following adjustment for differences in clinical and procedural characteristics, TFA was independently associated with higher odds for mortality [adjusted odds ratio (aOR): 1.3 (1.1-1.7)], major bleeding [aOR: 2.9 (2.3-3.4)], and MACCE (following propensity score matching) [aOR: 1.2 (1.1-1.4)]. The same was found with multiple accesses: mortality [aOR: 2.1 (1.5-2.8)], major bleeding [aOR: 5.5 (4.3-6.9)], and MACCE [aOR: 1.4 (1.2-1.7)]. CONCLUSION TRA has become the predominant access site for CHiP procedures and is associated with significantly lower mortality, major bleeding and MACCE odds than TFA.

Sex-based treatment and outcomes for coronary bifurcation stenting: A report from the e-ULTIMASTER registry. Catheter Cardiovasc Interv 2023; 102:430-439. [PMID: 37464969 DOI: 10.1002/ccd.30770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Revised: 06/02/2023] [Accepted: 07/09/2023] [Indexed: 07/20/2023]
Abstract
BACKGROUND Percutaneous coronary intervention (PCI) for bifurcation lesions can be technically challenging and is associated with higher risk. There is little data on sex-based differences in strategy and outcomes in bifurcation PCI. AIMS We sought to assess whether differences exist between women and men in the treatment and outcomes of bifurcation PCI. METHODS We collected data on 4006 patients undergoing bifurcation PCI, from the e-ULTIMASTER study, a prospective, multicentre study enrolling patients from 2014 to 2018. We divided the bifurcation cohort according to sex, with 1-year follow-up of outcomes (target lesion failure [TLF], target vessel failure [TVF], and patient-oriented composite endpoint [POCE]). FINDINGS Women were older (69.2 ± 10.9 years vs. 64.4 ± 11.0 years), with a greater burden of cardiovascular comorbidities. For true and non-true bifurcation lesions, women and men were equally likely to undergo a single stent approach (true: 63.2% vs. 63.6%, p = 0.79, non-true: 95.4% vs. 94.3%, p = 0.32), with similar rates of final kissing balloon (FKB) (37.2% vs. 35.5%, p = 0.36) and proximal optimization (POT) (34.4% vs. 34.2%, p = 0.93) in cases where two stents were used. Lastly, after propensity score matching, there was no difference between women and men in the incidence of the composite endpoints of TLF (5.5% vs. 5.2%, RR 1.05 [95% CI 0.77-1.44], p = 0.75), TVF (6.2% vs. 6.3%, RR 0.99 [95% CI 0.74-1.32], p = 0.96), and POCE (9.9% vs. 9.5%, RR 1.05 [95% CI 0.83-1.31], p = 0.70). CONCLUSION In this contemporary, real-world study of bifurcation PCI, we report no difference in stent strategy between women and men, with similar outcomes at 1-year.

Comparison of Outcomes of Elective Percutaneous Coronary Intervention between Complex and High-Risk Intervention in Indicated Patients (CHIP) versus Non-CHIP. J Atheroscler Thromb 2023; 30:1229-1241. [PMID: 36529503 PMCID: PMC10499455 DOI: 10.5551/jat.63956] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Accepted: 10/31/2022] [Indexed: 09/05/2023] Open
Abstract
AIMS Complex and high-risk intervention in indicated patients (CHIP) is an emerging concept in the contemporary percutaneous coronary intervention (PCI). CHIP is known to consist three factors, namely, (1) patient factors, (2) complicated heart disease, and (3) complex PCI. However, it remains unclear whether additional CHIP factors further increase the incidence of complications in complex PCI. Thus, in this study, we aim to compare the incidence of complications among definite CHIP, possible CHIP, and non-CHIP in terms of complex PCI and to further investigate the association between CHIP and complications. METHODS The primary aim of this study was to determine the major complications in PCI. We included 989 PCI lesions and divided those into definite CHIP (n=140), possible CHIP (n=397), and the non-CHIP groups (n=452). RESULTS The incidence of major complications was noted to be the highest in the definite CHIP, followed by the possible CHIP, and lowest in the non-CHIP (p=0.001). The multivariate logistic regression analysis using a generalized estimating equation revealed definite CHIP (versus non-CHIP: odds ratio (OR) 2.099, 95% confidence interval (CI) 1.062-4.150, p=0.033) was significantly associated with major complications after controlling for confounding factors. Another multivariate logistic regression analysis revealed immunosuppressive drugs (OR 3.040, 95% CI 1.251-7.386, p=0.014), unstable hemodynamics (OR 5.753, 95% CI 1.217-27.201, p=0.027), and frailty (OR 2.039, 95% CI 1.108-3.751, p=0.022) were significantly associated with major complications among CHIP factors. CONCLUSIONS The incidence of major complications in complex PCI was determined to be the highest in the definite CHIP, followed by the possible CHIP and lowest in the non-CHIP. Thus, more attention should be given to the three components of CHIP to prevent major complications in complex PCI.

Sex Differences in pLVAD-Assisted High-Risk Percutaneous Coronary Intervention: Insights From the PROTECT III Study. JACC Cardiovasc Interv 2023:S1936-8798(23)00806-3. [PMID: 37409991 DOI: 10.1016/j.jcin.2023.04.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 04/04/2023] [Accepted: 04/11/2023] [Indexed: 07/07/2023]
Abstract
BACKGROUND Prior studies have found that female patients have worse outcomes following high-risk percutaneous coronary intervention (HRPCI). OBJECTIVES The authors sought to evaluate sex-based differences in patient and procedural characteristics, clinical outcomes, and safety of Impella-supported HRPCI in the PROTECT III study. METHODS We evaluated sex-based differences in the PROTECT III study; a prospective, multicenter, observational study of patients undergoing Impella-supported HRPCI. The primary outcome was 90-day major adverse cardiac and cerebrovascular events (MACCE)-the composite of all-cause death, myocardial infarction, stroke/transient ischemic attack, and repeat revascularization. RESULTS From March 2017 to March 2020, 1,237 patients (27% female) were enrolled. Female patients were older, more often Black, more often anemic, and had more prior strokes and worse renal function, but higher ejection fractions compared to male patients. Preprocedural SYNTAX score was similar between sexes (28.0 ± 12.3). Female patients were more likely to present with acute myocardial infarction (40.7% vs 33.2%; P = 0.02) and more often had femoral access used for PCI and nonfemoral access used for Impella device implantation. Female patients had higher rates of immediate PCI-related coronary complications (4.2% vs 2.1%; P = 0.004) and a greater drop in SYNTAX score post-procedure (-22.6 vs -21.0; P = 0.04). There were no sex differences in 90-day MACCE, vascular complications requiring surgery, major bleeding, or acute limb ischemia. After adjustment using propensity matching and multivariable regression, immediate PCI-related complications was the only safety or clinical outcome that was significantly different by sex. CONCLUSIONS In this study, rates of 90-day MACCE compared favorably to prior cohorts of HRPCI patients and there was no significant sex differences. (The PROTECT III Study is a substudy of The Global cVAD Study [cVAD]; NCT04136392).

Comparison of Long-Term Clinical Outcomes of Elective Percutaneous Coronary Intervention Between Complex and High-risk Intervention in Indicated Patients (CHIP) versus Non-CHIP. Am J Cardiol 2023; 194:1-8. [PMID: 36913903 DOI: 10.1016/j.amjcard.2023.02.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 02/07/2023] [Accepted: 02/08/2023] [Indexed: 03/15/2023]
Abstract
Recently, there has been a growing interest in complex and high-risk intervention in indicated patients (CHIP) in the contemporary percutaneous coronary intervention (PCI). CHIP is composed of the following 3 factors: (1) patient factors, (2) complicated heart disease, and (3) complex PCI. However, there are few studies that investigated the long-term outcomes of CHIP-PCI. The purpose of this study was to compare the incidence of long-term major adverse cardiovascular events (MACEs) among the definite CHIP, possible CHIP, and non-CHIP groups in complex PCI. We included 961 patients and divided them into the definite CHIP (n = 129), the possible CHIP (n = 369), and the non-CHIP groups (n = 463). During the median follow-up duration of 573 days (quartile 1:226 days to quartile 3:1,165 days), a total of 189 MACE were observed. The incidence of MACE was highest in the definite CHIP group, followed by the possible CHIP group, and lowest in the non-CHIP group (p = 0.001). Definite CHIP (vs non-CHIP: odds ratio 3.558, 95% confidence interval 2.249 to 5.629, p <0.001) and possible CHIP (vs non-CHIP: odds ratio 2.260, 95% confidence interval 1.563 to 3.266, p <0.001) were significantly associated with MACE after controlling for confounding factors. Among CHIP factors, active malignancy, pulmonary disease, hemodialysis, unstable hemodynamics, left ventricular ejection fraction, and valvular disease were significantly associated with MACE. In conclusion, the incidence of MACE in complex PCI was highest in the definite CHIP group, followed by the possible CHIP group, and lowest in the non-CHIP group. The concept of CHIP should be recognized to predict the long-term MACE in patients who undergo complex PCI.

Impact of Sex on Clinical Outcomes in Patients undergoing Complex Percutaneous Coronary Angioplasty (from the e-ULTIMASTER Study). Am J Cardiol 2023; 186:71-79. [PMID: 36368145 DOI: 10.1016/j.amjcard.2022.10.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 10/03/2022] [Accepted: 10/13/2022] [Indexed: 11/10/2022]
Abstract
Female gender has been shown to be associated with worse clinical outcomes after percutaneous coronary intervention (PCI). However, the impact of gender on the clinical outcomes of complex PCI is still poorly understood. This study examined the differences in patient and coronary lesion characteristics and longer-term clinical outcomes in male and female patients who underwent complex PCI. This was a sub-analysis of the e-ULTIMASTER study, which was a large, multicontinental, prospective, observational study enrolling 37,198 patients who underwent PCI with the Ultimaster stent. Patients who underwent complex PCI were stratified by gender. The primary outcome was target lesion failure at 12 months, defined as the composite of cardiac death, target vessel-related myocardial infarction, and clinically driven target lesion revascularization at 12 months. A total of 13,623 patients underwent complex procedures, of which 35.7% were women. Women were twice as likely as men to be aged ≥80 years (17.6% vs 9%, p <0.0001) and had a higher prevalence of cardiovascular risk factors. Women had fewer lesions treated than men (1.5 ± 0.8 vs 1.6 ± 0.8, p <0.0001) and fewer stents implanted (2.0 ± 1.1 vs 2.1 ± 1.1, p <0.0001). There was no statistically significant difference in clinical outcomes at 12 months between women and men. Event rates were comparable in women and men for target lesion failure (4.7% vs 4.3%, p = 0.30), target vessel failure (5.1% vs 4.9%, p = 0.73), and cardiac death (1.8% vs 1.7%, p = 0.80).In conclusion, our findings suggest no significant differences in clinical outcomes between women and men who underwent complex PCI.

Abstract
This review evaluates published data regarding outcomes for women with ACS undergoing PCI. Data is discussed from a patient centred perspective and timeline, beginning with sex-based differences in perception of risk, time to presentation, time to treatment, access to angiography, access to angioplasty, the impact of incomplete revascularization, prescribing practices, under-representation of women in randomized controlled trials and in cardiology physician workforces. The objective of the review is to identify factors contributing to outcome disparities for women with ACS, and to discuss potential solutions to close this outcome gap.

Complex, high-risk percutaneous coronary intervention types, trends, and in-hospital outcomes among different age groups: An insight from a national registry. Catheter Cardiovasc Interv 2022; 100:711-720. [PMID: 36054239 PMCID: PMC9826050 DOI: 10.1002/ccd.30366] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 08/09/2022] [Indexed: 01/11/2023]
Abstract
BACKGROUND Complex, high-risk percutaneous coronary intervention (PCI) (CHiP) is increasingly being undertaken in octogenarians. However, limited data exist on CHiP types, trends, and outcomes in the octogenarian. METHODS This is a retrospective cohort study from a national registry dataset on CHiP undertaken in patients with stable angina in England and Wales (January 2006 and December 2017) according to three age groups (group 1 [G1]: < 65 years; group 2 [G2]: 65-79 years; and group 3 [G3]: ≥80 years). RESULTS Of 424,290 elective PCI procedures, 138,831 (33.0%) were CHiP [G1: 46,832 (33.7%); G2: 59,544 (42.9%); G3: 32,455 (23.4%)]. Among CHiP types, chronic total occlusion (CTO) (49.2%), prior coronary artery bypass graft (CABG) (30.4%), and severe vascular calcification (21.8%) were common in G1; prior CABG (42.9%), CTO (32.9%), and severe vascular calcifications (27%) were common in G2; prior CABG (15.8%), severe vascular calcification (15.5%), and chronic renal failure (11.1%) were common CHiP among the octogenarians. The older age groups had higher adjusted odds (aOR) for adverse outcomes [G2: mortality, aOR 1.7, 95% confidence interval (CI): (1.3-2.3); major bleeding, aOR 1.3, 95% CI (1.1-1.5); MACCE, aOR 1.2, 95% CI (1.0-1.3); G3: mortality, aOR 2.6, 95%CI (1.9-3.6); major bleeding, aOR 1.4, 95% CI (1.1-1.7); MACCE, aOR 1.3, 95% CI (1.1-1.5)]. CONCLUSION There were significant differences in the types of CHiP cases undertaken and clinical outcomes across age groups.
