The prevalence of calcification in obstructive coronary artery disease is on the rise. Percutaneous coronary intervention of these calcified lesions is associated with increased short-term and long-term risks. To optimize percutaneous coronary intervention results, there is an expanding array of treatment modalities geared toward calcium modification prior to stent implantation. The Society for Cardiovascular Angiography and Interventions, herein, puts forth an expert consensus document regarding methods to identify types of calcified coronary lesions, a central algorithm to help guide use of the various calcium modification strategies, tips for when using each treatment modality, and a look at future studies and trials for treating this challenging lesion subset.

BACKGROUND: Little is known about the procedural characteristics, case volumes, and mortality rates for early- vs non-early-career interventional cardiologists in the United States. OBJECTIVES: This study examined operator-level data for patients who underwent percutaneous coronary intervention (PCI) between April 2018 and June 2022. METHODS: Data were collected from the National Cardiovascular Data Registry CathPCI Registry, American Board of Internal Medicine certification database, and National Plan and Provider Enumeration System database. Early-career operators were within 5 years of the end of training. Annual case volume, expected mortality and bleeding risk, and observed/predicted mortality and bleeding outcomes were evaluated. RESULTS: A total of 1,451 operators were early career; 1,011 changed their career status during the study; and 6,251 were non-early career. Overall, 514,540 patients were treated by early-career and 2,296,576 patients by non-early-career operators. The median annual case volume per operator was 59 (Q1-Q3: 31-97) for early-career and 57 (Q1-Q3: 28-100) for non-early-career operators. Early-career operators were more likely to treat patients presenting with ST-segment elevation myocardial infarction and urgent indications for PCI (both P < 0.001). The median predicted mortality risk was 2.0% (Q1-Q3: 1.5%-2.7%) for early-career and 1.8% (Q1-Q3: 1.2%-2.4%) for non-early-career operators. The median predicted bleeding risk was 4.9% (Q1-Q3: 4.2%-5.7%) for early-career and 4.4% (Q1-Q3: 3.7%-5.3%) for non-early-career operators. After adjustment, an increased risk of mortality (OR: 1.08; 95% CI: 1.05-1.17; P < 0.0001) and bleeding (OR: 1.08; 95% CI: 1.05-1.12; P < 0.0001) were associated with early-career status. CONCLUSIONS: Early-career operators are caring for patients with more acute presentations and higher predicted risk of mortality and bleeding compared with more experienced colleagues, with modestly worse outcomes. These data should inform institutional practices to support the development of early-career proceduralists.

PURPOSE OF REVIEW: This review focuses on the use of colchicine to target inflammation to prevent cardiovascular events among those at-risk for or with established coronary artery disease. RECENT FINDINGS: Colchicine is an anti-inflammatory drug that reduces cardiovascular events through its effect on the IL-1ß/IL-6/CRP pathway, which promotes the progression and rupture of atherosclerotic plaques. Clinical trials have demonstrated that colchicine reduces cardiovascular events by 31% among those with chronic coronary disease, and by 23% among those with recent myocardial infarction. Its ability to dampen inflammation during an acute injury may broaden its scope of use in patients at risk for cardiovascular events after major non-cardiac surgery. Colchicine is an effective anti-inflammatory therapy in the prevention of acute coronary syndrome. Ongoing studies aim to assess when, and in whom, colchicine is most effective to prevent cardiovascular events in patients at-risk for or with established coronary artery disease.

BACKGROUND: Women with myocardial infarction (MI) are more likely to have elevated stress levels and depression than men with MI. OBJECTIVES: We investigated psychosocial factors in women with myocardial infarction with nonobstructive coronary arteries (MINOCA) and those with MI and obstructive coronary artery disease (CAD). METHODS: Women with MI enrolled in a multicenter study and completed measures of perceived stress (Perceived Stress Scale-4) and depressive symptoms (Patient Health Questionnaire-2) at the time of MI (baseline) and 2 months later. Stress, depression, and changes over time were compared between MI subtypes. RESULTS: We included 172 MINOCA and 314 MI-CAD patients. Women with MINOCA were younger (age 59.4 years vs 64.2 years; P < 0.001) and more diverse than those with MI-CAD. Women with MINOCA were less likely to have high stress (Perceived Stress Scale-4 ≥6) at the time of MI (51.0% vs 63.0%; P = 0.021) and at 2 months post-MI (32.5% vs 46.3%; P = 0.019) than women with MI-CAD. There was no difference in elevated depressive symptoms (Patient Health Questionnaire-2 ≥2) at the time of MI (36% vs 43%; P = 0.229) or at 2 months post-MI (39% vs 40%; P = 0.999). No differences in the rate of 2-month decline in stress and depression scores were observed between groups. CONCLUSIONS: Stress and depression are common among women at the time of and 2 months after MI. MINOCA patients were less likely to report high stress compared with MI-CAD patients, but the frequency of elevated depressive symptoms did not differ between the 2 groups. Stress and depressive symptoms decreased in both MI-CAD and MINOCA patients over time.

Optimal timing for aortic valve replacement in symptomatic patients with less than severe aortic stenosis (AS) is not well defined. There is limited information on the benefit of valve replacement in these patients. Symptomatic patients with less than severe AS, defined as a mean aortic gradient ≥20 and <40 mm Hg, peak aortic velocity >3 and <4 m/s, and aortic valve area >1.0 and <1.5 cm2, enrolled in the Society for Thoracic Surgery/American College of Cardiology Transcatheter Valve Therapy Registry and who underwent attempted supra-annular, self-expanding transcatheter aortic valve replacement (TAVR) were reviewed. Site-reported valve hemodynamics, clinical events, and quality of life metrics were analyzed at 30 days and 1 year after the procedure. A total of 1,067 patients with attempted TAVR (mean age 78.4 ± 8.4 years; Society for Thoracic Surgery score 4.7 ± 3.4%) were found to have symptoms but less than severe AS. From baseline to postprocedure, mean gradient decreased (29.9 ± 4.9 vs 8.4 ± 4.8 mm Hg, p <0.001), and aortic valve area increased (1.2 ± 0.1 vs 2.2 ± 0.7 cm2, p <0.001). Clinical events included 30-day and 1-year all-cause mortality (1.5% and 9.6%), stroke (2.2% and 3.3%), and new pacemaker implantation (18.1% and 20.9%). There were statistically significant improvements in the New York Heart Association functional class and Kansas City Cardiomyopathy Questionnaire at 30 days and 1 year. In conclusion, patients with symptomatic but less than severe AS who underwent supra-annular, self-expanding TAVR experienced improved valve hemodynamics and quality of life measures 1 year after the procedure. Randomized studies of TAVR versus a control arm in symptomatic patients with less than severe AS are ongoing.

Periprocedural inflammation is associated with major adverse cardiovascular events in patients who undergo percutaneous coronary intervention (PCI). In the contemporary era, 5% to 10% of patients develop restenosis, and in the acute coronary syndrome cohort, there remains a 20% major adverse cardiovascular events rate at 3 years, half of which are culprit-lesion related. In patients at risk of restenosis, colchicine has been shown to reduce restenosis when started within 24 hours of PCI and continued for 6 months thereafter, compared with placebo. The Colchicine-PCI trial, which randomized patients to a 1-time loading dose of colchicine or placebo 1 to 2 hours before PCI, showed a dampening of the inflammatory response to PCI but no difference in postprocedural myocardial injury. On mean follow-up of 3.3 years, the incidence of major adverse cardiovascular events did not differ between colchicine and placebo groups (32.5% vs 34.9%; hazard ratio 0.95 [0.68 to 1.34]).

BACKGROUND: The role of cytoreduction prior to hematopoietic cell transplant (HCT) for patients with pediatric myelodysplastic syndrome (MDS) and related disorders remains unclear. PROCEDURE: We performed a single-center retrospective analysis of pre-transplant disease management and subsequent HCT outcome for pediatric patients with MDS and related disorders who underwent HCT between 2010 and 2020. RESULTS: Total 62 patients (median age 11 years) with idiopathic MDS (n = 16), MDS secondary to an underlying germline condition (n = 11), secondary acute myeloid leukemia (n = 9), myeloproliferative neoplasms (n = 8), and treatment-related myeloid neoplasms (n = 18) received an allogeneic HCT. Cytoreduction prior to HCT was performed in 30/62 (48%) patients; this subset of patients had higher risk disease characteristics, including a higher blast count on presentation. In the overall cohort, use of cytoreduction before HCT was associated with higher rates of relapse (cumulative incidence of relapse 24 months post HCT: 48.1% [27.5%-66.1%]) for those who received cytoreduction versus 16.6% (5.9%-32.1%) for those who did not (p = .03). There was a trend toward decreased overall survival (OS) for those patients who received cytoreduction (24 months post HCT 57.1% vs. 75.3%, respectively; p = .06). OS for patients who received cytoreduction and attained measurable residual disease (MRD) negativity prior to HCT was superior compared to those with persistent disease (24 months post HCT 63.9% [36%-81.2%] vs. 33.3% [7.8%-62.3%], respectively; p = .04). CONCLUSION: Cytoreduction did not provide survival benefit in our overall cohort, but its increased use in children with higher risk disease impacted the analysis. Patients receiving cytoreduction and achieving MRD-negative status before HCT demonstrated improved OS compared to those with persistent disease.

Background Angiotensin receptor neprilysin inhibitors (ARNI) reduce mortality and hospitalization for patients with heart failure. However, relatively high copayments for ARNI may contribute to suboptimal adherence, thus potentially limiting their benefits. Methods and Results We conducted a retrospective cohort study within a large, multi-site health system. We included patients with: ARNI prescription between November 20, 2020 and June 30, 2021; diagnosis of heart failure or left ventricular ejection fraction ≤40%; and available pharmacy or pharmacy benefit manager copayment data. The primary exposure was copayment, categorized as $0, $0.01 to $10, $10.01 to $100, and >$100. The primary outcome was prescription fill nonadherence, defined as the proportion of days covered <80% over 6 months. We assessed the association between copayment and nonadherence using multivariable logistic regression, and nonbinarized proportion of days covered using multivariable Poisson regression, adjusting for demographic, clinical, and neighborhood-level covariates. A total of 921 patients met inclusion criteria, with 192 (20.8%) having $0 copayment, 228 (24.8%) with $0.01 to $10 copayment, 206 (22.4%) with $10.01 to $100, and 295 (32.0%) with >$100. Patients with higher copayments had higher rates of nonadherence, ranging from 17.2% for $0 copayment to 34.2% for copayment >$100 (P<0.001). After multivariable adjustment, odds of nonadherence were significantly higher for copayment of $10.01 to $100 (odds ratio [OR], 1.93 [95% CI, 1.15-3.27], P=0.01) or >$100 (OR, 2.58 [95% CI, 1.63-4.18], P<0.001), as compared with $0 copayment. Similar associations were seen when assessing proportion of days covered as a proportion. Conclusions We found higher rates of not filling ARNI prescriptions among patients with higher copayments, which persisted after multivariable adjustment. Our findings support future studies to assess whether reducing copayments can increase adherence to ARNI and improve outcomes for heart failure.

Aims: We aimed to use optical coherence tomography (OCT) to identify differences in atherosclerotic culprit lesion morphology in women with myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) compared with MI with obstructive coronary artery disease (MI-CAD). Methods and results: Women with an OCT-determined atherosclerotic aetiology of non-ST segment elevation (NSTE)-MINOCA (angiographic diameter stenosis <50%) who were enrolled in the multicentre Women's Heart Attack Research Program (HARP) study were compared with a consecutive series of women with NSTE-MI-CAD who underwent OCT prior to coronary intervention at a single institution. Atherosclerotic pathologies identified by OCT included plaque rupture, plaque erosion, intraplaque haemorrhage (IPH, a region of low signal intensity with minimum attenuation adjacent to a lipidic plaque without fibrous cap disruption), layered plaque (superficial layer with clear demarcation from the underlying plaque indicating early thrombus healing), or eruptive calcified nodule.We analysed 58 women with NSTE-MINOCA and 52 women with NSTE-MI-CAD. Optical coherence tomography features of underlying vulnerable plaque (thin-cap fibroatheroma) were less common in MINOCA (3 vs. 35%) than in MI-CAD. Intraplaque haemorrhage (47 vs. 2%) and layered plaque (31 vs. 12%) were more common in MINOCA than MI-CAD, whereas plaque rupture (14 vs. 67%), plaque erosion (8 vs. 14%), and calcified nodule (0 vs. 6%) were less common in MINOCA. The angle of ruptured cavity was smaller and thrombus burden was lower in MINOCA. Conclusion: The prevalence of atherothrombotic culprit lesion subtype varied substantially between MINOCA and MI-CAD. A majority of culprit lesions in MINOCA had the appearance of IPH or layered plaque.

RÉSUMÉ
Randomized clinical trials have not demonstrated a survival benefit with percutaneous coronary intervention in stable ischemic heart disease (SIHD). We evaluated the generalizability of the COURAGE (Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation) trial findings to the broader population of veterans with SIHD. Veterans who underwent coronary angiography between 2005 and 2013 for SIHD were identified from the Veterans Affairs Clinical Assessment, Reporting and Tracking Program (VA CART). Patient-level comparisons were made between patients from VA CART who met the eligibility criteria for COURAGE and veterans enrolled in COURAGE between 1999 and 2004. All-cause mortality over long-term follow-up was assessed using Cox proportional hazards models. COURAGE-eligible patients from VA CART (nâ¯=â¯59,758) were older, had a higher body mass index, a greater prevalence of co-morbidities, but fewer diseased vessels on index coronary angiography, and were less likely to be on optimal medical therapy at baseline and on 1-year follow-up compared with VA COURAGE participants (nâ¯=â¯968). Patients from VA CART (median follow-up 6.5 years) had higher all-cause mortality (adjusted hazard ratio [aHR] 1.98 [1.61 to 2.43]) than participants from VA COURAGE (median follow-up: 4.6 years). Risks of mortality were greater in the 56.4% patients from CART who were medically managed (aHR 1.94 [1.49 to 2.53]) and in the 43.6% who underwent percutaneous coronary intervention (aHR 1.99 [1.45 to 2.74]), compared with their respective VA COURAGE arms. In conclusion, in this noncontemporaneous patient-level analysis, veterans in the randomized COURAGE trial had more favorable outcomes than the population of veterans with SIHD at large.

BACKGROUND: Type 2 myocardial infarction (MI) occurs due to a mismatch in myocardial oxygen supply and demand without unstable coronary artery disease. We sought to identify patterns, predictors and outcomes of invasive management of type 2 MI in the USA. METHODS: Adults aged ≥18 years hospitalized with type 2 MI were identified in a cross-sectional study from the 2018 National Inpatient Sample. Invasive management was defined as invasive coronary angiography or revascularization. Patient, hospital and geographic characteristics associated with invasive management were identified by multivariable logistic regression. Propensity-matched cohorts were generated to evaluate associations between invasive vs. conservative management and mortality. RESULTS: We identified 268 850 admissions with type 2 MI in 2018. Type 2 MI patients had a high burden of comorbidities and were commonly admitted with diagnoses of circulatory (39.7%), infectious (23.1%) or respiratory (10.8%) illness. Only 11.2% of type 2 MI were managed invasively, of which 17.9% underwent coronary revascularization. Odds of invasive management were higher with commercial insurance [adjusted OR (aOR) 1.39; 95% confidence interval (CI), 1.27-1.52] and lower with Medicaid (aOR 0.86; 95% CI, 0.76-0.96) vs. Medicare. Significant heterogeneity in invasive management of type 2 MI was observed by geographic region (range 7.2-13.8%), independent of patient and hospital factors. Invasive management was associated with lower in-hospital mortality than conservative management overall (3.9 vs. 9.1%; P < 0.001) and in propensity-matched analyses (OR, 0.70; 95% CI, 0.59-0.84). CONCLUSION: Invasive management of type 2 MI varies by insurance status and geography, highlighting uncertainty regarding optimal management and potential disparities in clinical care.
