PRECISE-DAPT, ARC-HBR, or Simplified Clinical Evaluation for the Prediction of Major Bleeding After Percutaneous Coronary Intervention in older Patients.

Older patients have been remarkably underrepresented in bleeding risk cohorts. Thus, the PRECISE-DAPT (Derivation and validation of the predicting bleeding complications in patients undergoing stent implantation and subsequent dual antiplatelet therapy) and Academic Research Consortium for High Bleeding Risk (ARC-HBR) scores are not validated in older adults. Therefore, we sought to evaluate the PRECISE-DAPT and ARC-HBR scores in an exclusively older population and assess the prognostic value of a truly simplified clinical evaluation (SCE), consisting of only 3 binary clinical variables (hemoglobin <11 g/100 ml, previous bleeding, and anticipated use of anticoagulants). This is a retrospective analysis of the prospective single-center older-HCD registry. Consecutive patients aged ≥75 years who underwent percutaneous coronary intervention from 2012 to 2019 were included. The primary end point was postdischarge bleeding at 12 months of follow-up, defined according to the Bleeding Academic Research Consortium 3 or 5 criteria. A total of 693 patients with a mean age of 81 (±4.4) years were included in the study and 60 patients (6.8%) met the primary end point. The PRECISE-DAPT and ARC-HBR scores did not significantly predict postdischarge bleeding in the Cox regression models (hazard ratio 1.65 [0.78 to 3.42] and 1.46 [0.72 to 4.24], respectively), whereas the SCE outperformed both scores (hazard ratio 2.47, 1.34 to 4.49). All 3 scores exhibited a moderate discriminatory potential, as determined by a receiver-operating characteristic curve analysis (areas under the curve 0.601, 0.621, and 0.616, respectively), with no significant differences between them. The SCE showed an Integrated Discrimination Improvement of 0.25, p = 0.02 (SCE vs ARC-HBR) and 0.24, p = 0.01 (SCE vs PRECISE-DAPT), with an Net Reclassification Improvement of 6.54%, p = 0.37 and 7.12%, p = 0.43, respectively. In conclusion, the PRECISE-DAPT score and ARC-HBR criteria showed insufficient predictive value in older adults. A truly SCE consisting of 3 easily accessible variables not only provides equal discriminatory potential but also demonstrates superior predictive value, as determined by Cox regression models. This makes it a highly appealing tool for risk stratification, pending its evaluation in larger prospective studies.

Spanish cardiac catheterization and coronary intervention registry. 32nd official report of the Interventional Cardiology Association of the Spanish Society of Cardiology (1990-2022).

INTRODUCTION AND OBJECTIVES: This article presents the annual activity report of the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) for the year 2022. METHODS: All Spanish centers with catheterization laboratories were invited to participate. Data were collected online and were analyzed by an external company in collaboration with the members of the board of the ACI-SEC. RESULTS: A total of 111 centers participated. The number of diagnostic studies increased by 4.8% compared with 2021, while that of percutaneous coronary interventions (PCI) remained stable. PCIs on the left main coronary artery increased by 22%. The radial approach continued to be preferred for PCI (94.9%). There was an upsurge in the use of drug-eluting balloons, as well as in intracoronary imaging techniques, which were used in 14.7% of PCIs. The use of pressure wires also increased (6.3% vs 2021) as did plaque modification techniques. Primary PCI continued to grow and was the most frequent treatment (97%) in ST-segment elevation myocardial infarction. Most noncoronary procedures maintained their upward trend, particularly percutaneous aortic valve implantation, atrial appendage closure, mitral/tricuspid edge-to-edge therapy, renal denervation, and percutaneous treatment of pulmonary arterial disease. CONCLUSIONS: The Spanish cardiac catheterization and coronary intervention registry for 2022 reveals a rise in the complexity of coronary disease, along with a notable growth in procedures for valvular and nonvalvular structural heart disease.

Incidence and Predictors of Progression in Asymptomatic Patients With Stable Heart Failure.

Data from previous heart failure (HF) trials suggest that patients with mild symptoms (NYHA II) actually have a poor clinical outcome. However, these studies did not assess clinical stability and rarely included patients in NYHA I. We sought to determine the incidence of short-term clinical progression in supposedly stable HF patients in NYHA I. In addition, we aimed to investigate the predictive value of widely available electrocardiographic and echocardiographic parameters for short-term disease progression. This is a retrospective study including 153 consecutive patients with HF with reduced and mid-range ejection fraction (HFrEF: LVEF<40%; HFmrEF: LVEF 40-49%) in NYHA I with no history of decompensation within the previous 6 months. All patients underwent comprehensive baseline echocardiographic and electrocardiographic assessment. The primary endpoint was the composite of cardiovascular death, hospitalization and need for intensification of HF treatment within a 12 month follow-up period. The cumulative incidence of HF progression was 17.8%, with a median time to event of 193 days. Death and hospitalization due to HF accounted for three-quarters of the events. QRS duration ≥120ms and mitral regurgitation grade >1 showed to be significant predictors of HF progression (HR: 8.92, p<0.001; and HR: 4.10, p<0.001, respectively). Patients without these risk factors had a low incidence of clinical events (3.8%). In conclusion, almost one in five supposedly stable HF patients in NYHA I experience clinical progression in short-term follow-up. Simple electrocardiographic and echocardiographic predictors may be useful for risk stratification and could help to improve individual HF patient management and outcomes.

Atrial cholangiocarcinoma diagnosed by cardiac magnetic resonance imaging.

In this rare case of intrahepatic cholangiocarcinoma (ICC) tumor thrombus with right atrial (RA) invasion, we describe its diagnostic workup based on cardiac magnetic resonance imaging (cMRI). An 85-year-old man underwent transthoracic echocardiography due to dyspnea, revealing a RA mass. Comprehensive cMRI evaluation, including cine bright blood, T1- and T2-weighed, fat-suppressed, and contrast-enhanced imaging, was performed and diagnosis of ICC tumor thrombus with RA invasion was made. This first description of cMRI-guided diagnosis of RA invasion by ICC tumor thrombus points out the usefulness of cMRI for the diagnostic approach of RA masses suggestive of tumor thrombus.

Clinical risk factors for the prediction of acute kidney injury post cardiac resynchronization therapy in an elderly population.

BACKGROUND: Data on the occurrence of acute kidney injury (AKI) in patients undergoing cardiac resynchronization therapy (CRT) implantation is limited and no previous studies investigated its impact in an elderly population. CRT implantation requires a relatively low quantity of contrast medium. Previous studies, however, focused primarily on contrast medium as etiological factor for AKI, reporting a high incidence (8-14%). The high incidence of AKI in absence of use of substantial amounts of contrast volume, suggests the existence of other factors that contribute to AKI. OBJECTIVES: To determine the predictive value of patient and procedure-related risk factors for the occurrence of AKI post CRT, as well as the AKIs impact on length of in-hospital stay (LOS) and 1-year mortality. METHODS: Retrospective observational study, including consecutive patients that underwent CRT implantation in a single center. RESULTS: 60 patients with a mean age of 77 ± 8.4 years were included in the study and Twelve (20%) developed AKI. Prior renal insufficiency (p = 0.03; OR = 15.4), larger procedure time (p = 0.02; OR = 1.03), intra-operative hypotension (p < 0.01; OR = 1.72) and bleeding (p = 0.01 (OR = 7.86), showed to predict AKI significantly. AKI associated a significantly longer LOS (12 vs 3 days, p < 0.01). No significant differences regarding 1-year mortality were observed (p = 0.19; HR = 2.7 for patients with AKI). CONCLUSIONS: AKI is a frequent complication of CRT implantation with an important impact on in-hospital stay, especially in the elderly. In addition to contrast administration, clinical factors could play a significant role in the occurrence of AKI.

Impact of Anemia on the Risk of Bleeding Following Percutaneous Coronary Interventions in Patients ≥75 Years of Age.

Bleeding risk stratification is an unresolved issue in older adults. Anemia may reflect subclinical blood losses that can be exacerbated after percutaneous coronary intervention . We sought to prospectively determine the contribution of anemia to the risk of bleeding in 448 consecutive patients aged 75 or more years, treated by percutaneous coronary interventions without concomitant indication for oral anticoagulation. We evaluated the effect of WHO-defined anemia on the incidence of 1-year nonaccess site-related major bleeding. The prevalence of anemia was 39%, and 13.1% of anemic and 5.2% of nonanemic patients suffered a bleeding event (hazard ratio 2.75, 95% confidence interval 1.37 to 5.54, p = 0.004). Neither PRECISE-DAPT nor CRUSADE scores were superior to hemoglobin for the prediction of bleeding. In conclusion, anemia is a powerful predictor of bleeding with potential utility for simplifying tailoring therapies.
