Abstract

Background
A substantial proportion of ST-segment elevation myocardial infarction (STEMI) patients has no standard modifiable cardiovascular risk factors (SMuRF) at admission. Knowledge on pathogenesis and risk markers of mortality in these patients remain limited.

Aims
We described the characteristics and prognosis of SMuRF-less patients admitted for a first STEMI in the light of recent prognostic biomarkers.

Methods
Baseline characteristics including interleukin (IL)-1β, hs-CRP and serum cholesterol efflux capacity were compared between patients with and without SMuRF. Determinants of 1-year all-cause mortality were assessed using univariable and multivariable Cox regression analyses.

Results
Among the 1604 patients included, 178 (11.1%) were SMuRF-less. SMuRF-less patients were older (66.9 ± 15.3 vs 61.9 ± 13.9, p&lt;0.001), less often men (66.9 vs 75.9%, p&lt;0.001) and had lower body mass index (24.2 ± 3.9 vs 26.0 ± 4.4, p&lt;0.001) compared to patients with ≥1 SMuRFs. SMuRF-less patients presented higher rates of altered LVEF&lt;45% and killip≥2 at admission (31.8% vs 22.8%, p=0.014 and 19 vs 12.9%, respectively, p=0.027) without differences in proportions of late STEMI presenters (symptoms-to-balloon time &gt;360 min) did not differ between groups. SMuRF-less patients had lower rates of revascularization (82 vs 92.3%, p&lt;0.001) and received less guidelines recommended medications (statins, β-blockers or angiotensin-converting enzyme (ACE) inhibitors) at discharge; p&lt;0.001 for all. Compared to patients with SMuRF, SMuRF-less patients had lower serum cholesterol efflux capacity (0.79 ± 0.16 vs 0.83 ± 0.16, respectively, p&lt;0.001), were more often in the highest tertile of IL-1β (28.7% vs 18.9%, respectively, p=0.002) with a trend towards more patients within the highest hs-CRP level tertile (24.7% vs 19.1%, respectively, p=0.077). Crude rates of mortality were more than doubled in the SMuRF-less group (18.5% vs 7.7%, respectively, p&lt;0.001). After multivariable adjustment SMuRF-less status was associated with a higher rate of mortality at one year aHR 1.87 [1.05-2.38], p=0.029) as well as inflammation biomarkers IL-1β (HR 1.81 [1.23-2.66], p=0.003) and high tertiles of hs-CRP (HR 1.87 [1.31-2.66], p&lt;0.001) whereas having a high serum cholesterol efflux capacity was associated with a lower mortality (HR 0.27 [0.09-0.87], p=0.0208).

Conclusion
In STEMI patients, SMuRF-less patients have higher levels of inflammatory biomarkers and more frequent defective serum cholesterol efflux capacity, are undertreated, and have higher rate of mortality than patients with standard modifiable cardiovascular risk factors. Optimized management of such patients is needed.

Abstract

Background
Tricuspid regurgitation (TR) affects 7% of the population, contributing significantly to heart failure-related hospitalizations. Traditional treatments have several limitations, prompting the exploration of innovative interventions.

Purpose
The present study aims to investigate the efficacy of tricuspid valve transcatheter edge-to-edge repair (T-TEER) in real-world patients with severe and symptomatic TR deemed at high surgical risk. Primary objectives focus on assessing T-TEER-induced TR reduction and reverse structural remodeling of the RV. Secondary objectives include assessment of functional status, quality of life, and residual regurgitation during the 12-month follow-up period.

Methods
The TR-Interventional study (TRIS) is a prospective, single-arm study. From January 2021 to December 2023, we enrolled 44 symptomatic patients with at least severe TR referred for TEER. Outcomes included safety and effectiveness along with assessment of clinical status.

Results
The study cohort had a mean age of 78.3±7 years, with 77.3% women and a mean TRISCORE of 5.1±1.9. Seventeen patients (38.6%) had massive, 7 (15.9%) had torrential, and 20 (45.5%) patients had severe TR. Etiologies included functional (40.9%), degenerative (13.64%), lead-induced (15.9%), and mixed (29.54%) origin. The primary efficacy endpoint, which assesses the successful implantation and performance of the device at the 30-day mark, was attained in 82.9% of patients. The secondary efficacy endpoint, assessing the stability of TR reduction at the 12-month, was achieved in 82,3% of patients. Post-procedural TR reduction of at least 2 degrees was achieved in 84% of patients. Echocardiographic assessments indicate ongoing beneficial remodeling over the one-year follow-up (Figure 1). Effects on RV remodeling also became apparent at the one-year follow-up, including reductions in the RV end-diastolic basal (p&lt;0.01) and medium (p= 0.04) diameters of the TA septal-lateral diameter (p&lt; 0.01). Significant reduction in vena contracta width (9 mm to 3 mm; p=&lt;0.01), regurgitant volume (58 ml to 30 ml; p&lt;0.01), and effective regurgitant orifice area (EROA) (0.6 cm2 to 0.3 cm2; p&lt;0.01), occurred between baseline and one-year follow-up (Figure 2). The NYHA Functional Class and KCCQ scores were improved from 30 days to 1 year (Figure 2).

Conclusion
TRIS suggests that T-TEER is a durable, effective, and safe therapeutic option for high-risk patients with severe TR. The enduring nature of TR reduction at one year correlates with sustained clinical benefits and reverse structural remodeling of the right ventricle.TR reductionNYHA and functional status
In-hospital outcomes of acute myocardial infarction patients without standard modifiable cardiovascular risk factors across varying body mass index
Authors: Yang Y , Ma X , Gao F , Wang Z 
Published: October 2024

Abstract

Background
Individuals who present with acute myocardial infarction (AMI) in the absence of standard modifiable cardiovascular risk factors (i.e., SMuRF-less) seem to have a significantly increased risk of mortality; however, it remains unclear whether the ‘SMuRF paradox’ would be influenced by patients’ baseline body mass index (BMI) status.

Purpose
To assess the disparities in the prevalence and prognostic implications of SMuRF-less among patients with newly diagnosed AMI across varying body mass index (BMI).

Methods
Using data from the Improving Care for Cardiovascular Disease in China–Acute Coronary Syndrome (CCC–ACS) project, we retrospectively analyzed AMI patients with and without SMuRFs and categorized their baseline BMI as underweight (&lt;18.5kg/m2), normal weight (18.5-24kg/m2), overweight (24-28kg/m2), and obese (&gt;28kg/m2). The primary outcome was in-hospital all-cause mortality. Multivariable logistic regression models were used to estimate BMI-stratified associations between SMuRF-less and each outcome, sequentially adjusting for demographic, clinical characteristics, and prevention strategies.

Results
Between 2014 and 2019, 44,538 adult patients hospitalized for first-presentation AMI were included, of which 4,454 (10.0%) were SMuRF-less. The incidence of SMuRF-less declined from 16.2% to 6.5% as BMI increased by category, and it prevailed more frequently among females and elders regardless of their BMI status. During the median hospital stay of 9 days, SMuRF-less patients had a significant increase in in-hospital mortality than patients with one or more SMuRF (2.1% vs. 1.0%, adjusted odds ratio [OR], 1.750 [95% CI 1.057–2.896], P&lt;0.001). The highest mortality rate was observed in the SMuRF-less underweight group (3.5%). Took ≥1 SMuRF and obese as the reference group as they presented the finest outcome, SMuRF-less underweight group exhibited the highest increase in mortality (3.5% vs 0.5%, adjusted odds ratio [OR], 3.854 [95% CI 2.130–6.973], P&lt;0.001). However, interaction analyses provided no evidence that BMI significantly modifies SMuRF-less’s association with in-hospital mortality (P for interaction=0.247).

Conclusion
Approximately one-tenth of first-presentation AMI patients had no SMuRF, who were more frequently women, elders, and underweight. Compared with those with at least one SMuRF, SMuRF-less patients have a significantly higher risk of in-hospital mortality, especially in those underweight, while in-hospital survival was the most favorable among ≥1 SMuRF and obese patients.

Abstract

Background
Patients with metabolic dysfunction-associated steatotic liver disease (MASLD) are at increased risk of incident cardiovascular disease. However, the clinical characteristics and prognostic importance of MASLD in patients presenting with acute myocardial infarction (AMI) have yet to be examined.

Methods
This study compared the characteristics, and outcomes of patients with and without MASLD presenting with AMI at a tertiary centre in Singapore. MASLD was defined as hepatic steatosis, with at least one of five metabolic criteria. Hepatic steatosis was determined using the Hepatic Steatosis Index. Propensity score matching was performed to adjust for age and sex. Kaplan-Meier curve was constructed for long-term all-cause mortality. Cox regression analysis was used to investigate independent predictors of long-term all-cause mortality.

Results
In this study of 4446 patients with AMI, 2223 patients with MASLD were matched with patients without MASLD using propensity scores. The mean follow-up duration was 3.4 ± 24 years. The MASLD group had higher rates of obesity, diabetes, and chronic kidney disease than their counterparts. Patients with MASLD had early excess all-cause mortality (6.8% vs 3.6%, p&lt;0.001) at 30 days, with unfavorable mortality rates sustained in the long-term (18.3% vs 14.5%, p=0.001) compared to those without MASLD. After adjustment, MASLD remained independently associated with higher long-term all-cause mortality (HR 1.338, 95% CI 1.115-1.604).

Conclusion
MASLD embodies a higher burden of metabolic dysfunction and is an independent predictor of long-term mortality in the AMI population. Its early identification may be beneficial for risk stratification and provide therapeutic targets for secondary preventive strategies in AMI.Kaplan Meier curve of long-term all-caus

Abstract

Introduction
Atrial fibrillation (AF) is a common cardiac arrhythmia associated with coronary artery disease (CAD) and myocardial infarction (MI). The prevalence of AF in patients following acute MI varies, with conflicting evidence on its impact on outcomes. Concomitant atrial fibrillation is associated with an adverse prognosis in patients with acute myocardial infarction (MI). However, it remains unclear whether this is due to a causal effect of AF, or whether AF acts as a surrogate marker for comorbidities in this population Also, there are limited data on whether coronary artery disease distribution impacts the risk of developing AF.

Purpose
This large cohort study aims to determine the prevalence of AF in acute MI patients treated with PCI, assess its independent prognostic value for MACCE, investigate the association of AF with CAD distribution patterns, and provide insights into the long-term outcomes of AF in this patient population.

Methods
A cohort of 1000 consecutive MI patients treated with PCI was retrospectively analyzed. Data on demographics, medical history, presentation, treatment, and outcomes was collected. Propensity score matching was used to adjust for baseline differences between AF and non-AF groups. CAD distribution, major adverse events, and MACCE were assessed using statistical analyses.

Results
Amongst the studied population, 6.5% people had AF (65/1000) and it was noted that those with AF had a worse outcome. However, on statistical analyses (both on multivariable cox and propensity matching) accounting for risk factors, outcomes were not significantly different between those with and without AF. Hence, this negated key baseline differences between AF and non-AF groups, with no significant differences in demographics or presentation.
Patients with AF had a higher prevalence of severe CAD in the left main stem (LMS) and left circumflex artery (LCx). The association of AF with MACCE was not significant in the matched groups. Long-term follow-up revealed similar rates of MACCE between AF and non-AF groups.

Discussion
AF in acute MI patients undergoing PCI is associated with a higher prevalence of severe CAD in the LMS and LCx. AF appears to be a surrogate marker of other risk factors, rather than an independent risk factor for MACCE. The study highlights the need for tailored aggressive treatment for risk factor modification in AF patients with MI.

Conclusions
AF is associated with an increased risk of MACCE in acute MI patients undergoing PCI. However, this association is primarily driven by the burden of comorbidities associated with AF, emphasizing the importance of tailored treatment strategies for AF patients. Prospective studies with routine ambulatory monitoring are recommended to validate these findings and guide future practice.

Abstract

Background
To identify anatomical and morphological plaque features predictors of percutaneous coronary intervention (PCI) and create a multiparametric score to increase the predictive yield. Moreover, we assessed the incremental predictive value of FFRCT (Fractional Flow Reserve derived from CCTA) trans-lesion gradient (ΔFFRCT) when integrated into the score.

Methods
Observational cohort study including patients undergoing CCTA for suspected coronary artery disease, with FFRCT available, referred to invasive coronary angiogram and assessment of fractional flow reserve. Plaque analysis was performed using validated semi-automated software. Logistic regression was performed to identify anatomical and morphological plaque features predictive of PCI. Optimal thresholds were defined by area under the receiver-operating characteristics curve (AUC) analysis. A scoring system was developed in a derivation cohort (70% of the study population) and tested in a validation cohort (30% of patients).

Results
The overall study population included 340 patients (455 vessels), among which 238 patients (320 vessels) were included in the derivation cohort. At multivariate logistic regression analysis, absence of left main disease, diameter stenosis (DS), non-calcified plaque (NCP) volume, and percent atheroma volume (PAV) were independent predictors of PCI. Optimal thresholds were: DS³50%, volume of NCP&gt;113 mm3 and PAV&gt;17%. A weighted score (CT-PCI Score) ranging from 0 to 11 was obtained. The AUC of the score was 0.80 (95%CI 0.74-0.86). The integration of ΔFFRCT in the CT-PCI score led to a mild albeit not significant increase in the AUC (0.82, 95%CI 0.77-0.87, p=0.328).

Conclusions
Plaque anatomy and morphology derived from CCTA could aid in identifying patients amenable to PCI.Central IllustrationPredictive accuracy of the CT-PCI score

Abstract

Background
Development of coronary artery disease (CAD) and risk of acute cardiac events differ between women and men during the life span. The aim of this study was therefore to characterize sex differences in coronary artery plaque phenotype among patients with symptomatic non-obstructive CAD in different age groups.

Methods
Advanced coronary artery plaque phenotyping by coronary computed tomography angiography was performed in 606 patients (31% women) with symptomatic non-obstructive CAD from the Norwegian Registry of Invasive Cardiology. A 1:1 sex-matched study design ensured equal distribution of the sexes in the different age groups. We assessed total plaque burden adjusted for vessel volume and plaque composition consisting of dense calcium, fibrous, fibro-fatty, and necrotic core. Patients were further stratified into age groups of ≤50, 51-64, and ≥65 years to explore the relationship between age and sex on coronary artery plaque phenotype.

Results
In the study population, patients ≥65 years had a higher prevalence of hypertension, higher calcium score, coronary artery segment involvement score and total plaque burden, whereas the prevalence of obesity was lower compared to patients aged 51-64 and ≤50 years (all p&lt;0.05). The prevalence of smoking, diabetes and statin treatment was similar between groups. A two-way analysis of variance demonstrated an interaction between sex and age group on total plaque burden (F [2, 600] =3.431, p=0.33), where women aged 51-64 and ≥65 years had a higher total plaque burden compared to men (p=0.002 and p&lt;0.001, respectively, Figure 1). Plaque composition in women ≥65 years was characterized by an increased proportion of stable dense calcified plaques compared to men and younger women (all p&lt;0.05), whereas men ≥65 years had a higher proportion of vulnerable necrotic core plaque phenotype (p&lt;0.001). Women showed consistently lower proportions of more vulnerable fibro-fatty plaques compared to men across all age groups (all p&lt;0.05, Figure 2).

Conclusions
In non-obstructive CAD, higher total plaque burden was associated with older age and female sex. Women had a lower proportion of vulnerable fibro-fatty plaques across all age groups and a higher proportion of stable dense calcified plaques at an older age compared to men. Future longitudinal studies on coronary artery plaque phenotype during the life span will increase the understanding of sex differences in CAD development and may contribute to customise risk stratification in women and men.Figure 1.Total plaque burdenFigure 2.Compositional plaque burden
Prognostic implication of computational angiography-derived fractional flow reserve in patients with non-obstructive coronary artery disease

Abstract

Background
Non-obstructive coronary artery disease (NOCAD) is proved to have high association with rate of major adverse cardiovascular events (MACE) in recent studies, yet risk stratification of symptomatic Non-Obstructive Coronary Artery Disease (NOCAD) patients remains uncertain.

Objectives
Our study assessed clinical value of single-vessel, multi-vessel, and three-vessel computational angiography-derived fractional flow reserve (caFFR) measurement in NOCAD patients.

Methods
We enrolled patients with ≤ 50% stenosis with a caFFR value ≥ 0.8 in all three coronary arteries on coronary angiography. The sum of caFFR values in the three vessels was computed for each patient. Patient stratification was based on median value of the following criteria: single vessel analysis, multi-vessel analysis, 3-vessel (3V) analysis. The primary endpoint of this study was major adverse cardiac events (MACE) at 5 years, defined as a composite of cardiac death, myocardial infarction, and ischemia-driven revascularization.

Results
A total of 490 patients were included (mean age 64.39 ± 11.16, 55.5% male). The 5-year MACE rates in single-vessel analysis were statistically insignificant between low and high caFFR groups (Left anterior descending artery (P=0.163); Left circumflex artery (P=0.797); Right coronary artery (P=0.127)). In multi-vessel analysis, patients in multiple-vessel low-caFFR group (with 2-3 vessels lower than median value of all coronary arteries) show an increased risk of 5-year MACE than patients in single-vessel low-caFFR group (0-1 vessel) (hazard ratio [HR] 2.648, 95% confidence interval [CI] 1.141 - 6.145, P = 0.023). In 3-vessel analysis, patients in the low 3V-caFFR group demonstrated a greater 5-year MACE risk than the high 3V-caFFR group ([HR] 2.43, 95% 95%[CI] 1.087 - 5.433, P = 0.031).

Conclusion
In patients with NOCAD, the higher count of vessels exhibiting with low caFFR values and the low 3V-caFFR values have been found to be associated with increased rate of MACE over a 5-year period. We demonstrated that both multiple-vessel and 3V-caFFR measurements serve as valuable prognostic indicators for risk assessment in NOCAD patients.
Comparison of vessel-Fractional Flow Reserve (vFFR) and Quantitative Flow Ratio (QFR) using instantaneous wave-Free Ratio (iFR) or Resting Full-cycle Ratio (RFR) as reference

Abstract

Background
Angiography-based functional assessment remains the state of the art to assess the hemodynamic relevance of intermediate coronary stenoses. In addition to fractional flow reserve (FFR), adenosin free indices like instantaneous wave-free ratio (iFR) or resting full-cycle ratio (RFR) are widely used for the invasive evaluation. Although these methods are widely accepted, they are underused in clinical routine due to costs, their invasive nature, longer procedural times, and lack of availability. Vessel-fractional flow reserve (vFFR) and quantitative flow ratio (QFR) are new software-based methods for the evaluation of coronary-physiology. The aim of this study is to compare vFFR and QFR with the established invasive methods iFR or RFR.

Methods
We prospectively analyzed 95 Patients in our QFR-Registry vFFR- and QFR-computation was performed three-times by two certified, blinded, and independent experts using the QAngio XA 3D 3.2- and CAAS-software, respectively.
Results: 101 main epicardial coronary arteries (52 LAD; 19 LCx; 30 RCA) were analyzed using vFFR, QFR and iFR or RFR. vFFR showed a good correlation with adenosine-free indices in all 3 measurements (AUC 0.883 with r=0.672, p&lt;0.001; AUC 0.841 with r=0.618 p&lt;0.001; AUC 0.840 with r=0.592, p&lt;0.001 respectively). The diagnostic accuracy between the three vFFR-measurements and iFR/RFR was 83%; 81% and 79% respectively. QFR-computations showed a similar correlation with iFR/RFR (AUC 0.899 with r=0.720, p&lt;0.001; AUC 0.919 with r=0.649, p&lt;0.001; AUC 0.930 with r=0.703, p&lt;0.001 respectively) with a diagnostic accuracy 88%, 89% and 88% respectively. The intra- and inter-observer reliability for vFFR (intra: mean difference 0.002±0.0568; inter: 0.024±0.054) and QFR (intra: mean difference 0.018±0.071; inter: 0.016±0.075) analyzed in a Bland-Altman Blot showed a good correlation between virtual assessments and invasive measurements with iFR/RFR.

Conclusion
The data show a good diagnostic agreement between vFFR and QFR and adenosine free invasive assessments. vFFR and QFR appear reasonable alternative approaches for the evaluation of intermediate stenoses. These data provide the rational to prospectively test for a clinical noninferiority of the non-invasive flow measurements.Diagnostic performance of vFFR/cQFR
