Epidemiology and Prognostic Implications of Coronary Artery Calcium in Asymptomatic Individuals With Prediabetes: A Multicohort Study. Diabetes Care 2024; 47:698-706. [PMID: 38329795 DOI: 10.2337/dc23-1864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Accepted: 01/08/2024] [Indexed: 02/09/2024]
Abstract
OBJECTIVE To describe the epidemiology and prognostic value of coronary artery calcium (CAC) in individuals with prediabetes. RESEARCH DESIGN AND METHODS We pooled participants free of clinical atherosclerotic cardiovascular disease (ASCVD) from four prospective cohorts: the Multi-Ethnic Study of Atherosclerosis, Heinz Nixdorf Recall Study, Framingham Heart Study, and Jackson Heart Study. Two definitions were used for prediabetes: inclusive (fasting plasma glucose [FPG] ≥100 to <126 mg/dL and hemoglobin A1c [HbA1c] ≥5.7% to <6.5%, if available, and no glucose-lowering medications) and restrictive (FPG ≥110 to <126 mg/dL and HbA1c ≥5.7% to <6.5%, if available, among participants not taking glucose-lowering medications). RESULTS The study included 13,376 participants (mean age 58 years; 54% women; 57% White; 27% Black). The proportions with CAC ≥100 were 17%, 22%, and 37% in those with euglycemia, prediabetes, and diabetes, respectively. Over a median (25th-75th percentile) follow-up time of 14.6 (interquartile range 7.8-16.4) years, individuals with prediabetes and CAC ≥100 had a higher unadjusted 10-year incidence of ASCVD (13.4%) than the overall group of those with diabetes (10.6%). In adjusted analyses, using the inclusive definition of prediabetes, compared with euglycemia, the hazard ratios (HRs) for ASCVD were 0.79 (95% CI 0.62, 1.01) for prediabetes and CAC 0, 0.70 (0.54, 0.89) for prediabetes and CAC 1-99, 1.54 (1.27, 1.88) for prediabetes and CAC ≥100, and 1.64 (1.39, 1.93) for diabetes. Using the restrictive definition, the HR for ASCVD was 1.63 (1.29, 2.06) for prediabetes and CAC ≥100. CONCLUSIONS CAC ≥100 is frequent among individuals with prediabetes and identifies a high ASCVD risk subgroup in which the adjusted ASCVD risk is similar to that in individuals with diabetes.

Abstract
Pre-existing coronary artery disease (CAD), and thrombotic, inflammatory, or virus infectivity response phenomena have been associated with COVID-19 disease severity. However, the association of candidate single nucleotide variants (SNVs) related to mechanisms of COVID-19 complications has been seldom analysed. Our aim was to test and validate the effect of candidate SNVs on COVID-19 severity. CARGENCORS (CARdiovascular GENetic risk score for Risk Stratification of patients positive for SARS-CoV-2 [COVID-19] virus) is an age- and sex-matched case-control study with 818 COVID-19 cases hospitalized with hypoxemia, and 1636 controls with COVID-19 treated at home. The association between severity and SNVs related to CAD (n = 32), inflammation (n = 19), thrombosis (n = 14), virus infectivity (n = 11), and two published to be related to COVID-19 severity was tested with adjusted logistic regression models. Two external independent cohorts were used for meta-analysis (SCOURGE and UK Biobank). After adjustment for potential confounders, 14 new SNVs were associated with COVID-19 severity in the CARGENCORS Study. These SNVs were related to CAD (n = 10), thrombosis (n = 2), and inflammation (n = 2). We also confirmed eight SNVs previously related to severe COVID-19 and virus infectivity. The meta-analysis showed five SNVs associated with severe COVID-19 in adjusted analyses (rs11385942, rs1561198, rs6632704, rs6629110, and rs12329760). We identified 14 novel SNVs and confirmed eight previously related to COVID-19 severity in the CARGENCORS data. In the meta-analysis, five SNVs were significantly associated to COVID-19 severity, one of them previously related to CAD.

Five-Year Changes in Inflammatory, Metabolic, and Oxidative Biomarkers and 10-Year Cardiovascular Disease Incidence: The REGICOR Cohort Study. Int J Mol Sci 2023; 24:ijms24097934. [PMID: 37175639 PMCID: PMC10178750 DOI: 10.3390/ijms24097934] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 04/18/2023] [Accepted: 04/20/2023] [Indexed: 05/15/2023] Open
Abstract
Ischemic cardiovascular diseases (CVD) originate from an imbalance between atherosclerotic plaque formation, instability, and endothelial healing dynamics. Our aim was to examine the relationship between 5-year changes in inflammatory, metabolic, and oxidative biomarkers and 10-year CVD incidence in a population without previous CVD. This was a prospective cohort study of individuals aged 35-74 years (n = 419) randomly selected from 5263 REGICOR participants without CVD recruited in 2005. Biomarkers were measured at baseline and in 2010. Participants were followed up until 2020 for a composite CVD endpoint including coronary artery disease, stroke, and peripheral artery disease. We used Cox regression to analyze the effect of biomarker levels on the occurrence of the composite endpoint, adjusted for traditional CVD risk factors and baseline levels of each biomarker. Individuals with elevated IL-6 or insulin after 5 years had a higher independent risk of CVD at 10 years, compared to those with lower levels. Each rise of 1 pg/mL of IL-6 or 10 pg/mL of insulin increased the 10-year risk of a CVD event by 32% and 2%, respectively. Compared to a model with traditional CVD risk factors only, the inclusion of IL-6 and insulin improved continuous reclassification by 51%. Elevated serum levels of IL-6 and insulin were associated with a higher risk of CVD at 10 years, independently of traditional CVD risk factors.

Abstract
OBJECTIVES Coronary lithotripsy (CL) works by fracturing the calcified plaque, allowing mean area gain, enhancing vessel compliance, and facilitating stent deployment. This study reports the safety, effectiveness, and durability of the clinical benefit of CL at long-term follow-up of a real-world multicenter registry. METHODS This was a prospective, multicenter, single-arm study that included consecutive patients with calcified lesions undergoing CL from August, 2018 to October, 2020 with a clinical follow-up of 20 months (interquartile range, 14.5-25). Exclusion criteria were a target lesion located in a vessel <2.5 mm and/or the presence of dissection prior to CL. The primary endpoint was the rate of major adverse cardiovascular event (MACE, defined as death or target-lesion revascularization [TLR] or myocardial infarction [MI]) at follow-up. RESULTS This registry included 109 patients (128 lesions). The population was elderly (mean age, 74 years old), with high rates of diabetic patients (58%), renal insufficiency (32%), and multivessel disease (76%). Most of the lesions were predilated with semicompliant/noncompliant balloons (25 with cutting balloon). Rotational atherectomy was used in 20 lesions. On average, CL required the use of 1 balloon delivering a mean of 60 pulses. Twelve patients presented with ST-segment-elevation MI and a culprit calcified coronary lesion undergoing CL. Successful CL was achieved in 99% of cases. There were few procedural complications, with 30-day freedom from MACE rate of 98%. The MACE rate at long-term follow-up was 5.6%. CONCLUSION This is the first real-world, multicenter registry that confirms the safety and long-term efficacy of percutaneous coronary intervention for calcified lesions using CL in an unselected and high-risk population with a low long-term follow-up MACE rate.

Abstract
BACKGROUND This study reports procedural and short-term clinical outcomes from a real-world series with the use of coronary lithotripsy in the context of primary angioplasty in ST-segment elevation myocardial infarction (STEMI). METHODS AND RESULTS This was a prospective registry conducted at 2 hospitals, which included 10 patients who presented a culprit calcified lesion within acute STEMI and underwent coronary lithotripsy during primary angioplasty, between July 2019 and July 2020. Mean age was 69.2 ± 11.8 years, and there was a high proportion of hypertension (70%) and dyslipidemia (60%). All lesions (type B/C) were predilated with a semicompliant balloon. Coronary lithotripsy was performed in all cases once macroscopic thrombus was successfully retrieved by thrombus aspiration catheter. Before lithotripsy, rotational atherectomy was used in 1 case and cutting balloon was used in 2 cases. On average, coronary lithotripsy required the use of 1 lithotripsy balloon (range, 1-2) delivering a mean of 70 pulses. Two lithotripsy balloons were ruptured during lithotripsy therapy without any adverse event. Successful coronary lithotripsy was achieved in 90%. There were no periprocedural cardiac complications. CONCLUSIONS Coronary lithotripsy seems to be a safe and effective technique in patients with STEMI and a culprit calcified lesion undergoing primary angioplasty for calcium modification in the absence of angiographic thrombus, and a suitable option to achieve adequate stent expansion and apposition.

Background
Although myocardial infarction (MI) severity trends are systematically measured with mortality rates, MI incidence trends and the precision of its estimation by linkage of anonymized electronic databases are relatively untested. We validated a linked-data method (LDM) to estimate a population MI incidence and case-fatality, and to analyse the 1990-2016 trends in North-Eastern Spain.
Methods
LDM consisted of linking MI hospital discharges (n = 4,533,981) and mortality registry data (n = 40,676) for 2008-2016, selecting key MI diagnostic codes. The prospective REGICOR study, including all MI cases in Girona, 1990-2009, was used as the gold standard for validation purposes. Standardized MI cumulated incidence and 28-day case fatality for population aged 35-74 years was calculated, 1990-2016 trends were analysed by linear and joinpoint regression and annual percentage change (APC).
Results
LDM and REGICOR MI incidence and case-fatality estimates were similar for 2008-09 (Table). LDM MI incidence and case-fatality significantly decreased: APC 1990-2016 [95% CI]) was -1.8 [-2.6;-0.9] in women, and APC 2002-2016 -2.8 [-3.8;-1.8] in men; case-fatality APC 1990-2016 was -4.7% [-5.7;-3.8] in women and APC 1995-2005 -6.5%[-8.5;-4.5] in men.
Conclusions
LDM in population aged 35-74 reliably estimated MI incidence and case-fatality. MI incidence and case-fatality significantly decreased after 1990.

Abstract
The LAmbreTM device is a novel system designed for left atrial appendage closure (LAAC). First registries showed a high rate of device implantation success. However, few mid-term results are available. We present our 1- and 12-month follow-up results for this device. This prospective, single-center registry included consecutive patients with nonvalvular atrial fibrillation who underwent LAAC with the LAmbreTM device. Transesophageal echocardiography (TEE) was performed at 1-month follow-up. In total, 55 patients were included. The population was elderly (75 ± 9.4 years), with a high proportion of comorbidities. The mean CHA2DS2-VASc and HAS-BLED scores were 4.6 ± 1.6 and 3.9 ± 1.0, respectively. Previous history of a major bleeding event was present in 37 patients (67.3%). Procedural success was achieved in 54 patients (98.2%). Device success was achieved in 100% of patients in whom device implantation was attempted (54 patients). Major in-hospital device-related complications included mortality of one patient (1.8%) and pericardial tamponade in two patients (3.6%); the incidence of stroke was 0%. No thrombus or significant leaks (≥5 mm) were observed on 1-month TEE. At 12 months, adverse events were overall death (1.8%), transient ischemic attack/ischemic stroke (1.8%), and major bleeding events (Bleeding Academic Research Consortium (BARC) 3a and 3c; 11%). In this high-risk population, the LAmbreTM device seems to be a safe and effective option for LAAC with a remarkable mid-term performance.

Similar degree of intimal coverage and apposition among drug-eluting stents with persistent, absorbable or without polymer at 1 and 6 months after implantation. Eur Heart J 2020.

Abstract
Abstract
Background
Despite technological advances in drug-eluting stents (DES) design, delayed vascular healing is still a problem, triggered by the polymers among others. This may induce restenosis and thrombosis. The development of biodegradable polymers and DES without polymer is thought to improve the vascular response and enhance earlier neointimal healing. Optical coherence tomography (OCT) is the best intracoronary imaging tool to evaluate endothelial coverage after stent implantation.
Purpose
We aimed to quantitatively assess the differences on intimal coverage between biodegradable-polymer, durable-polymer and without-polymer DES at 1 and 6-month follow-up OCT.
Methods
A total of 94 patients with de novo coronary lesions were treated with DES: 26% were treated with Biolimus A9 (BA9) stent without polymer, 30% were treated with Everolimus DES with biodegradable polymer (EESb) and 44% with Everolimus DES with persistent polymer (EESp). OCT analysis was performed blindly at an independent Core Lab at three stages: implantation, after one month and after six months.
The primary endpoint was to compare neointimal coverage and apposition of these three different types of DES with OCT at one and six months after implantation.
Results
A total of 16034 struts were analysed (24% BA9, 29% EESb and 47% EESp). No significant differences were found among the groups regarding baseline clinical characteristics. When studying the strut coverage, it is remarkable the relatively low percentage of early neointimal coverage with no significant differences among stents one month after implantation (84–87%). After six months, there was better coverage in the three stent groups compared with one month (p<0.001). The stents without polymer had better neointimal coverage at six months compared with the stents with persistent polymer (99% vs 92%, p=0.0002). No significant differences were found in the strut apposition after one or six months among the three stent types. However, the rate of apposition was higher after six months compared with one month in all stent groups (p=0,001). No significant differences were found in the neointimal hyperplasia at one month among the three stent groups. At six months there was a higher hyperplasia in the stent without polymer compared to the stent with persistent polymer (164μm vs 92μm, p=0,003). The degree of hyperplasia after six months was higher compared to one month in all groups (p=0,001).
Conclusions
The new-generation DES with biodegradable-polymer or without polymer showed relatively poor early neointimal coverage and similar to the last generation durable-polymer EES. According to these results, DAPT may not be shortened in any of the three DES types studied.

Abstract
OBJECTIVE Relationship between STEMI time of presentation, its circadian pattern and cardiovascular outcomes is unclear. Our objective is to analyze clinical outcomes of STEMI according to time of presentation and circadian pattern. METHODS We analyzed data from patients treated within the regional STEMI Network from January 2010 to December 2015. On-hour group included patients treated between 8:00 h and 19:59 h on weekdays, the rest were catalogued as off-hour group. The primary endpoint was 1-year all-cause mortality. Secondary endpoints were 30-day all-cause mortality and in-hospital complications. RESULTS A total of 8608 patients were included, 44.1% in the on-hour group and 55.9% in the off-hour group. We observed a shorter patient delay and longer system delay in the off-hour group compared to on-hour group with no difference in total ischemic time. At 30-day and 1-year follow-up there were no differences in adjusted all-cause mortality between groups [OR 0.91 (CI95%: 0.73-1.12; p = 0.35) and OR 0.99 (CI95%: 0.83-1.17; p = 0.87), respectively]. A circadian pattern was observed between 9:00 am and 12:30 pm, with no differences in 30-day and 1-year mortality between patients included in this time interval [OR 1.02 (IC95%: 0.81-1.30; p = 0.85) and OR 1.12 (IC95%: 0.92-1.36; p = 0.25) respectively]. CONCLUSIONS Off-hour STEMI presentation was associated with a shorter patient delay and longer system delay without an increase in total ischemic time. The off-hour presentation was not related to an increase in 1-year all-cause mortality when compared to on-hour. A circadian pattern was found, without differences in 30-day and 1-year mortality.

Abstract
AIM Primary percutaneous coronary intervention with stent implantation is the recommended treatment for patients with ST elevation myocardial infarction (STEMI). Data from randomised trials showed good performance by a titanium-nitric-oxide coated stent in this context. The aim of this study was to confirm these data. METHODS A multicentre registry was compiled in 23 hospitals in Spain in an all-comers population. We selected patients with STEMI from a global Titan AMI registry that included patients with acute coronary syndrome. Primary endpoint was the composite of cardiac death, non-fatal myocardial infarction, stent thrombosis and target lesion revascularisation, at 12-month follow-up. RESULTS The study included 893 patients with STEMI. We included all possibilities for PCI: 86.6% primary, 5% facilitated after successful fibrinolysis and 8.4% rescue PCI after failed fibrinolysis. The primary endpoint was reached in 8.4% of the patients: cardiac death 2.7%, reinfarction 3.4%, target lesion revascularisation 3.5% and definite or probable stent thrombosis 2.8%. The majority of stent thromboses presented in the first 30 days after PCI. CONCLUSION A bioactive stent (titanium-nitric-oxide coated stent) is a possible alternative for the treatment of patients with STEMI. One-year follow-up showed better results than those presented by a regular bare-metal stent or first-generation drug-eluting stent in terms of stent thrombosis.

Abstract
BACKGROUND Late-presenting ST-elevation myocardial infarction (STEMI) patients possess larger, more organized coronary thrombus leading to greater ventricular remodeling and arrhythmia despite angioplasty and pharmacological therapies. We hypothesized that myocardial injury would be reduced in late STEMI by proximal embolic protection (PEP). METHODS 31 patients with first STEMI 12-24 hr after pain onset and TIMI 0-1 flow were treated with or without PEP (cohort design matched for age, gender, and infarct-related artery). Contrast-enhanced magnetic resonance determined myocardial function, area at risk, necrosis, salvaged myocardium, and arrythmogenic peri-infarct region. Clinical follow-up was performed. RESULTS Pain to balloon time was 18 hr (95% CI 15.5-21.2 h), and Q waves were present in 87%. Angioplasty was performed with PEP in 15 and without in 16. Left ventricular (LV) volumes and ejection fraction were similar (EF 46.9% vs. 49.0% without PEP, P = 0.9). Although myocardial necrosis was similar (32.5 vs. 37.3% of LV, P = 0.3), PEP improved microvascular obstruction (8.7 vs. 11.2% of LV, P = 0.02) salvaged myocardium (39.6% vs. 29.6% of area at risk, P = 0.001), and the peri-infarct region (20.9 vs. 29.6% of infarct, P < 0.0001). On multivariate analysis, the use of PEP was an independent predictor of decreased arrythmogenic peri-infarct region and greater myocardial salvage. CONCLUSION In this pilot study, PEP improved myocardial salvage and the arrythmogenic peri-infarct region in late-presentation STEMI. Randomized trials are required to assess the clinical impact of improving salvaged myocardium and the peri-infarct region with PEP.
