Introduction
With the advent of modern pharmacological therapies and advanced interventional strategies, there is growing interest in reassessing the heart's capacity for functional recovery. Understanding the interplay between myocardial damage, therapeutic intervention, and potential reversibility is essential for optimizing long-term outcomes in patients with ischemic heart failure.
Objective
To identify predictors of improving Left ventricular contractility after myocardial infarction.
Method
We conducted a retrospective study including all patients admitted to the Cardiology Department at Hedi Chaker University Hospital between April 1, 2022, and March 31, 2023, with a diagnosis of ST-elevation myocardial infarction (STEMI). Clinical, echocardiographic, and angiographic data were collected and analyzed. Left ventricular ejection fraction (LVEF) was assessed by experienced operators. Left ventricular dysfunction was defined as LVEF < 40%, and improvement was defined as LVEF > 40%. Revascularization indications followed international guidelines.
Results
A total of 342 patients with STEMI were included. The prevalence of LV dysfunction was 28.65%, with 98 patients having an initial LVEF < 40% on admission. Among them, only 25 patients (25.5%) underwent a follow-up echocardiography at 40 days post-STEMI, and 17 of those showed improved LVEF (> 40%). Multivariate analysis identified three independent predictors of improved LVEF: optimal heart failure treatment including the four recommended drug classes (P < 0.001; OR = 2.46), female sex (P = 0.001; OR = 4.61), and good adherence to therapy (P = 0.019; OR = 2.27). Smoking was less common among patients with improved LVEF but was not an independent predictor.
Conclusion
In our study, we evaluated the occurrence of improved ejection fraction in patients who developed heart failure following myocardial infarction. Female sex, adherence to therapy, and being discharged on optimal heart failure medication were associated with improved LVEF. These findings support the potential for recovery of systolic function under appropriate conditions.
随着现代药物治疗和先进介入策略的出现,人们对重新评估心脏功能恢复能力的兴趣越来越大。了解心肌损伤、治疗干预和潜在可逆性之间的相互作用对于优化缺血性心力衰竭患者的长期预后至关重要。目的探讨心肌梗死后左室收缩力改善的预测因素。方法回顾性研究,纳入2022年4月1日至2023年3月31日在Hedi Chaker大学附属医院心内科诊断为st段抬高型心肌梗死(STEMI)的所有患者。收集并分析临床、超声心动图和血管造影资料。由经验丰富的操作人员评估左室射血分数(LVEF)。左心室功能不全定义为LVEF <; 40%,改善定义为LVEF >; 40%。血运重建指征遵循国际指南。结果共纳入342例STEMI患者。左室功能障碍的患病率为28.65%,其中98例患者入院时初始LVEF为40%。其中,仅有25例(25.5%)患者在stemi后40天接受了随访超声心动图检查,其中17例患者LVEF改善(40%)。多变量分析确定了改善LVEF的三个独立预测因素:最佳心力衰竭治疗包括四种推荐的药物类别(P < 0.001; OR = 2.46),女性(P = 0.001; OR = 4.61),以及良好的治疗依从性(P = 0.019; OR = 2.27)。吸烟在LVEF改善的患者中较少见,但不是一个独立的预测因子。结论:在我们的研究中,我们评估了心肌梗死后心力衰竭患者射血分数改善的发生情况。女性、坚持治疗和出院时使用最佳心力衰竭药物与LVEF改善相关。这些发现支持在适当条件下收缩功能恢复的潜力。

Introduction
Risk stratification in patients with known coronary artery disease (CAD) remains a clinical challenge, especially in asymptomatic individuals. While stress cardiac magnetic resonance imaging (MRI) has strong prognostic value, current models do not fully exploit the richness of available clinical and imaging data. Machine learning (ML) offers an opportunity to optimize prediction by capturing complex patterns in high-dimensional datasets.
Objective
To assess the performance of a supervised ML model combining clinical and stress cardiac MRI data for predicting 10-year major adverse cardiovascular events (MACE) in asymptomatic patients with obstructive CAD, compared to logistic regression models.
Method
A total of 966 asymptomatic patients with obstructive CAD who underwent vasodilator stress cardiac MRI between 2009 and 2011 in two centres were retrospectively included. The first centre (n = 742) provided a derivation cohort (n = 603) and an internal validation cohort (n = 139), while the second centre (n = 224) served as an external validation cohort. Feature selection was performed using LASSO, XGBoost, Random Forest (RF), and Boruta. A final RF model was trained using five selected variables and compared to a generalized logistic regression model (GLM) using AUROC and PRAUC metrics.
Results
Five key variables were selected: number of ischemic segments, number of late gadolinium enhancement (LGE) segments, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter indexed, and age (Figure 1). Over the 10-year follow-up period, MACE occurred in 28% of patients in the derivation cohort, 30% in the internal validation cohort, and 24% in the external test cohort. The RF model demonstrated the best predictive performance in the derivation cohort (AUROC: 0.99, PRAUC: 0.98). Consistently, the AUROC was 0.98 versus 0.86 for the GLM, and PRAUC was 0.97 versus 0.78 (all p < 0.001) in the internal validation cohort. In the external validation cohort, the RF model achieved an AUROC of 0.92 versus 0.74 for the GLM, and a PRAUC of 0.84 versus 0.58 (all p < 0.001). SHAP analysis confirmed the interpretability of the model and the individual contribution of each variable (Figure 2).
Conclusion
A ML model combining stress cardiac MRI and clinical data significantly outperformed traditional methods in predicting MACE in asymptomatic patients with obstructive CAD.

Introduction
Endothelial dysfunction is an early marker of vascular injury in CAD. While traditional risk factors are known, psychological stress—measured by the Perceived Stress Scale (PSS)—may also impact vascular health, though its role in predicting endothelial dysfunction is not well studied.
Objective
This study explores whether PSS stress scores are linked to endothelial function, assessing perceived stress as a potential early marker of vascular impairment in CAD patients.
Method
This observational study (Jan–Apr 2025) included Chronic Coronary Syndrome patients in follow-up. Stress was measured using the PSS, and endothelial function was evaluated via the Endothelium Quality Index (EQI).
Results
Among 51 CAD patients (mean age 57.86 years; 43 men, 8 women), the prevalence of hypertension, diabetes, and dyslipidemia was 66.6%, 60.78%, and 25.49%, respectively. Endothelial function, assessed by the Endothelial Quality Index (EQI), revealed severe dysfunction (EQI < 1) in 9 patients, moderate dysfunction (1 ≤ EQI < 2) in 21, and normal function (EQI ≥ 2) in 21. Poorly controlled hypertension and diabetes were present in 15% and 23% of patients, respectively. No significant association was found between endothelial dysfunction and traditional risk factors, but higher PSS scores were significantly correlated with worse endothelial function (P = 0.028, r = –0.38) (Fig. 1).
Conclusion
In chronic coronary syndrome patients, traditional risk factors were not significantly linked to endothelial dysfunction, likely due to well-controlled comorbidities. However, higher perceived stress levels were significantly associated with poorer endothelial function, suggesting that psychological stress could be an early marker of vascular impairment. Incorporating stress assessment into routine cardiovascular evaluations may improve early detection and prevention.

Introduction
In the third generation DES era, percutaneous coronary intervention now targets increasingly complex lesions, generating an expanding pool of instent restenosis (ISR). Its ideal treatment is debated. Drug-coated balloons (DCB) deliver metal free anti-proliferative therapy and represent a promising option, yet outcome data from Tunisia, remain scarce.
Objective
To assess immediate procedural success and long term clinical outcomes of DCB angioplasty for coronary IRS, and to identify independent predictors of MACE in an observational cohort of consecutive Tunisian patients treated for ISR lesions.
Method
We performed a retrospective single centre cohort at the Military Hospital of Tunis was reviewed over seven years (June 2014–July 2021). Eligible were all angiographically proven instent restenosis (ISR) lesions treated with paclitaxel drug-coated balloons (DCB). Two interventional cardiologists reinterpreted all images. Lesion preparation, DCB size and inflation were chosen after heart team discussion, except in ad hoc cases. Procedural success required residual stenosis ≤ 30%, TIMI3 flow and no in hospital complications. Patients attended follow-up at 1, 3 and 6 months, then biannually; survival, major adverse cardiac events (MACE) and target lesion revascularisation (TLR) were captured. The primary endpoint was MACE at 12 and 36 months, defined by ARC criteria.
Results
Among 68 consecutive patients treated with paclitaxelcoated drug-coated balloons (DCB) for coronary instent restenosis (ISR), mean age was 63 ± 0 years and 69% were diabetic. ACS presentation was common (63%). Immediate procedural success reached 91.2%, with a postdilatation minimal luminal diameter of 2.73 ± 0.4 mm and a median residual stenosis of 6.5%. Per-procedural complications were infrequent—two dissections (2.9%) and one slow flow episode. All lesions were predilated. Cumulative MACE occurred in 8.8% at 12 months and 23.1% at 36 months. TLR accounted for 13.2% of patients, whereas only one cardiovascular death and two definite/probable stent thromboses were recorded. On multivariable analysis, nonfocal ISR independently predicted TLR (hazard ratio 6.24, 95%CI 1.19–32.5; P = 0.03), while diabetes, vessel calibre, and procedural parameters were not significant.
Conclusion
Drug-coated balloon angioplasty achieved high procedural success and acceptable long-term safety. These results support DCB as a viable, metal-free strategy.
在第三代DES时代,经皮冠状动脉介入治疗现在针对越来越复杂的病变,产生了不断扩大的instent再狭窄(ISR)池。其理想的治疗方法备受争议。药物包覆气球(DCB)提供无金属抗增殖治疗,是一种有希望的选择,但来自突尼斯的结果数据仍然很少。目的评估DCB血管成形术治疗冠状动脉内出血的即时手术成功和长期临床结果,并在突尼斯连续治疗ISR病变患者的观察队列中确定MACE的独立预测因素。方法在突尼斯军事医院进行回顾性单中心队列研究,历时7年(2014年6月- 2021年7月)。所有经血管造影证实的血管再狭窄(ISR)病变均采用紫杉醇药物包被球囊(DCB)治疗。两位介入心脏病专家重新解释了所有图像。除特殊病例外,病变准备、DCB大小和膨胀均经心脏科小组讨论后选择。手术成功要求残余狭窄≤30%,TIMI3血流,无院内并发症。患者分别在1个月、3个月和6个月随访,然后每半年随访一次;生存率、主要心脏不良事件(MACE)和靶病变血运重建(TLR)。根据ARC标准,主要终点是12个月和36个月的MACE。结果68例连续应用紫杉醇包被药物包被球囊(DCB)治疗冠脉支架再狭窄(ISR)的患者,平均年龄63±0岁,其中糖尿病患者占69%。ACS表现很常见(63%)。即刻手术成功率为91.2%,扩张后最小管径为2.73±0.4 mm,中位残余狭窄为6.5%。手术前并发症很少- 2例夹层(2.9%)和1例慢血流发作。所有病变均预扩张。12个月时累积MACE发生率为8.8%,36个月时为23.1%。TLR占患者的13.2%,而仅记录了1例心血管死亡和2例明确/可能的支架血栓形成。在多变量分析中,非局灶性ISR独立预测TLR(风险比6.24,95%CI 1.19-32.5; P = 0.03),而糖尿病、血管口径和程序参数无显著性。结论药物包被球囊血管成形术手术成功率高,长期安全性可接受。这些结果支持DCB作为一种可行的无金属策略。

Introduction
Out-of-hospital cardiac arrest (OHCA) remains a major cause of mortality and morbidity, with ischemic heart disease identified as its leading etiology. Early coronary angiography (CAG) is often performed in these patients, yet the prognostic value of initial coronary flow remains poorly explored.
Objective
To evaluate the prognostic impact of preprocedural TIMI flow in OHCA survivors and identify predictors of reduced flow.
Method
We conducted a retrospective single-center study using the PROCAT registry. We included 330 patients admitted to the ICU at Cochin Hospital between 2016 and 2022 who underwent early CAG after successful resuscitation from OHCA of presumed cardiac origin. Patients were classified into non-ischemic OHCA and ischemic OHCA, the latter further stratified by TIMI flow: preserved (TIMI flow 2–3) vs. reduced (TIMI flow 0–1). The primary endpoint was 1-year mortality.
Results
One-year mortality was significantly higher in non-ischemic OHCA (66.7%) versus ischemic OHCA groups (34.5% for TIMI 2–3 and 36.7% for TIMI 0–1). Neurological outcomes were similarly poorer in non-ischemic OHCA. Among ischemic OHCA, reduced TIMI flow was associated with younger age, ST elevation, obesity, and elevated troponin. In multivariate analysis, reduced TIMI flow was independently associated with 1-year mortality (alongside age, low-flow duration, and non-shockable rhythm).
Conclusion
In ischemic OHCA, reduced initial coronary flow prior to PCI is an independent predictor of mortality at one year. These findings support early coronary evaluation and revascularization when appropriate, and call for larger prospective studies to refine risk stratification and management strategies.

Introduction
Cardiovascular disease (CVD) is highly prevalent and remains a cause of great morbi-mortality worldwide. Growing evidence suggests clonal hematopoiesis of indeterminate potential (CHIP) as an independent cardiovascular risk factor worsening overall survival (OS). However, actual data either comes from large population databases with heterogeneous and/or poorly defined CVD or from smaller better-defined populations but with limited follow-up.
Objective
We aimed to thoroughly characterize the extent and severity of coronary artery disease (CAD) and OS in CHIP-positive patients using the COROL (COROonary disease clinico-biological determinants study) cohort which included patients undergoing coronarography and for which we now have up to 24 years of follow-up. We also evaluated if OS in CHIP-positive patients was similar depending on CAD treatment.
Method
We retrospectively analyzed data from the 2050 COROL patients included between 2000–2001 at CHU de Lille in France (Mean age: 61 years ± 12). Our primary focus was CAD lesions (% of stenosis) by coronarography, treatment (medical, angioplasty or surgery), CHIP (variant allele frequency (VAF) ≥ 2%, determined using a 70-gene NGS panel) and OS. Patients with no significant coronary lesion (<50%) served as controls. Statistical analysis included log-rank and Student analysis.
Results
Of the 1976/2050 patients that met inclusion criteria, CHIP was found in 28.5% (n = 478). DNMT3a, TET2 and ASXL1 accounted for two-third of the mutated genes. Preliminary results in 1466/1976 patients showed reduced median OS in CHIP-negative patients with ≥ 50% lesions compared to those with < 50% lesions. Median OS was worse in both CHIP-positive groups with no difference according to CAD status (Table 1). Moreover, no CAD treatment could reverse CHIP effect (Fig. 1).
Conclusion
Our study is the first to provide detailed information on CAD extent and treatment in CHIP-positive patients while offering more 20 years of follow-up. It shows an independent negative effect of CHIP on OS, which raises concerns about CHIP identification and CAD patients management.
心血管疾病(CVD)在世界范围内非常普遍,并且仍然是高发病率和高死亡率的原因之一。越来越多的证据表明,克隆造血潜能不确定(CHIP)是一个独立的心血管危险因素,会恶化总生存期(OS)。然而,实际数据要么来自具有异构和/或不明确CVD的大型人群数据库,要么来自较小的定义较好的人群,但随访有限。目的:我们旨在通过冠状动脉疾病临床生物学决定因素研究(COROL)队列,全面表征chip阳性患者冠状动脉疾病(CAD)和OS的程度和严重程度,其中包括接受冠状动脉造影的患者,我们现在有长达24年的随访。我们还评估了chip阳性患者的OS是否因CAD治疗而相似。方法回顾性分析法国CHU de Lille医院2000-2001年间的2050例COROL患者的资料(平均年龄:61岁±12岁)。我们的主要焦点是冠心病病变(狭窄的百分比),冠状造影,治疗(药物,血管成形术或手术),CHIP(变异等位基因频率(VAF)≥2%,使用70个基因NGS面板确定)和OS。无明显冠状动脉病变的患者(50%)作为对照组。统计分析包括log-rank和Student分析。结果在符合纳入标准的1976/2050例患者中,28.5% (n = 478)发现CHIP。DNMT3a、TET2和ASXL1占突变基因的三分之二。1466/1976患者的初步结果显示,与病变<; 50%的患者相比,≥50%的chip阴性患者的中位OS降低。两个chip阳性组的中位OS较差,但CAD状态无差异(表1)。此外,CAD治疗无法逆转CHIP效应(图1)。结论本研究首次提供了chip阳性患者冠心病程度和治疗的详细信息,并提供了超过20年的随访。这表明CHIP对OS有独立的负面影响,这引起了对CHIP识别和CAD患者管理的关注。

Introduction
After acute coronary syndrome (ACS), recurrence of ischemic events remains higher in patients with diabetes mellitus (DM) or aspirin resistance despite optimal antithrombotic treatment. Once-daily aspirin may not provide stable inhibition of platelet aggregation in patients with DM or aspirin resistance, leading to the recovery of platelet cyclooxygenase activity before the next dose. Aspirin twice a day (b. i.d.) offers a better cyclooxygenase-1 inhibition during 24 hours.
Objective
To determine if aspirin b.i.d. decreases major adverse cardiovascular events (MACE) compared to aspirin once a day in patients with DM or aspirin resistance after ACS.
Method
In this prospective multicenter trial, patients with ACS and DM or aspirin resistance defined as: (i) index event occurring under aspirin; (ii) body mass index ≥ 27 kg/m2); (iii) increased waist circumference were randomly assigned to aspirin once daily (100 mg) or b.i.d (100 mg morning and 100 mg evening). The primary objective was to demonstrate the superiority of aspirin b.i.d to reduce MACE (death, myocardial infarction, stroke, urgent coronary revascularization, acute arterial thrombotic event) after a follow-up of 18 months. The main secondary objective was the occurrence of BARC type 3 to 5 bleeding (Fig. 1).
Results
We enrolled 2485 participants in the study (mean age 62 ± 11 years, 77.2% of DM, 55.5% of ST-elevation segment myocardial infarction). A total of 2260 patients (90.9%) were treated with more potent P2Y12 inhibitors (i.e. ticagrelor; 73.7% or prasugrel; 17,2%) at the time of randomization and 94.4% of the population underwent coronary revascularization. Follow-up at 18 months for all patients and data monitoring in all centers are completed. A blinded adjudication of the primary endpoint and the safety endpoint has been performed. We anticipate a primary endpoint incidence of 22.5% among patients treated by aspirin once a day and 17.7% among patients treated by aspirin once daily with a significant reduction of MACE after a median follow-up of 18 months. No significant difference in BARC type 3 to 5 bleeding is expected between the two groups. Results will be expected at th end of the year 2025.
Conclusion
The ANDAMAN trial will fill this gap by evaluating whether the improved antiplatelet effect of aspirin b.i.d. translates into better clinical outcomes for patients with diabetes mellitus or aspirin resistance after acute coronary syndrome.

Introduction
Percutaneous coronary interventions (PCI) for chronic total occlusions (CTO) remain challenging procedures with controversial long-term clinical benefits.
Objective
We aimed to describe clinical outcomes in a retrospective cohort of patients who have undergone PCI, and evaluate the impact of a successful CTO-PCI on long-term major cardiovascular events (MACE), survival, rehospitalizations, symptoms, LVEF and myocardial ischemia up-to-8-years follow-up.
Method
We conducted an observational monocentric study including consecutive patients who underwent PCI for CTO by experienced operators in a French University hospital between January 2015 and December 2022. All patients had symptoms and/or proved myocardial ischemia. Patients were divided into two groups based on PCI success or failure. The primary endpoint was the occurrence of MACE, defined as the composite of cardiac death, non-fatal myocardial infarction, and target vessel revascularization up to 8 years follow-up.
Results
Of the 448 patients who underwent a CTO-PCI, 401 (89.5%) had a successful procedure, while 47 (10.5%) experienced a failed intervention. During a mean follow-up of 3.7 years, MACE occurred in 71 patients (15.8%), including 12 patients (25.5%) in the failed group and 59 patients (14.7%) in the successful group (HR 2.68 [1.42; 5.06]; P < 0.01) (Fig. 1). While both groups had similar baseline clinical risk profiles, the successful CTO-PCI group had higher overall survival rate (88.8% vs. 74.5%; HR 2.23 [1.17; 4.27]; P = 0.02) and significant improvements in left ventricular ejection fraction (LVEF) (P < 0.01) and NYHA class (P < 0.01). The J-CTO score was the only predictor of procedural failure (1.96 [1.44; 2.67]; P < 0.01).
Conclusion
Successful CTO-PCI, achieved in nearly 90% of patients in experienced hands, was associated with significant long-term benefits, including reduced MACE, improved survival, LVEF, and NYHA class, supporting the pursuit of this procedure in selected cases.
慢性全闭塞(CTO)的经皮冠状动脉介入治疗(PCI)仍然是具有挑战性的手术,长期临床疗效存在争议。目的:我们旨在描述一组接受PCI治疗的患者的临床结果,并评估成功的CTO-PCI治疗对长期主要心血管事件(MACE)、生存率、再住院率、症状、LVEF和心肌缺血的影响。方法:我们进行了一项观察性单中心研究,包括2015年1月至2022年12月在法国大学医院由经验丰富的操作员连续接受CTO PCI治疗的患者。所有患者均有症状和/或证实心肌缺血。根据PCI的成功与否将患者分为两组。主要终点是MACE的发生,定义为心脏性死亡、非致死性心肌梗死和靶血管重建术的复合,随访8年。结果448例接受CTO-PCI的患者中,401例(89.5%)手术成功,47例(10.5%)手术失败。在平均3.7年的随访中,MACE发生71例(15.8%),其中失败组12例(25.5%),成功组59例(14.7%)(HR 2.68 [1.42; 5.06]; P < 0.01)(图1)。虽然两组的基线临床风险相似,但成功的CTO-PCI组的总生存率更高(88.8% vs. 74.5%; HR 2.23 [1.17; 4.27]; P = 0.02),左心室射血分数(LVEF) (P < 0.01)和NYHA分级(P < 0.01)均有显著改善。J-CTO评分是手术失败的唯一预测因子(1.96 [1.44;2.67];P < 0.01)。结论:在经验丰富的患者中,近90%的患者获得了CTO-PCI的成功,这与显著的长期获益相关,包括降低MACE、提高生存率、LVEF和NYHA等级,支持在特定病例中采用该手术。

Introduction
Fragmented QRS complexes (fQRS), electrocardiographic markers of myocardial scarring/conduction abnormalities, are under investigation for prognostic value in heart failure (HF) with reduced left ventricular ejection fraction (LVEF).
Objective
To assess the association of fQRS with clinical outcomes in systolic HF (LVEF < 50%).
Method
Retrospective analysis of HF patients (LVEF < 50%). fQRS was defined by notching in R/S waves (≥ 2 contiguous leads; narrow/wide QRS criteria). Outcomes were analyzed using Cox models adjusted for clinical covariates.
Results
A total of 187 patients were enrolled, those with fQRS (34.8%) exhibited higher all-cause mortality vs. non-fQRS (unadjusted HR: 2.855, 95% CI 1.641–4.966, P = 0.0001; adjusted HR: 4.130, 95% CI 2.109–8.088, P = 0.0001) (Table 1). No significant associations with heart failure-related readmissions (HR: 1.084, P = 0.755), all-cause rehospitalizations (HR: 1.237, P = 0.357), or arrhythmic events (HR: 1.527, P = 0.717) were observed.
Conclusion
fQRS independently predicts mortality but not readmissions or arrhythmias in systolic HF, supporting its role in risk stratification.

Introduction
Inferior myocardial infarction (IMI), typically resulting from right coronary artery occlusion, may extend to the right ventricle (RV), increasing morbidity due to impaired cardiac output. Detecting RV involvement remains challenging, as clinical signs and standard ECG changes often lack diagnostic precision.
Objective
The aim of this study was to evaluate the utility of RV strain analysis in detecting RV involvement in patients with IMI and to assess its correlation with conventional echocardiographic parameters.
Method
This cross-sectional observational study was conducted in the Cardiology Department of Charles Nicolle Hospital. It included patients admitted to the intensive care unit for acute inferior myocardial infarction between January 2022 and December 2024.
Results
During the 24-month study period, 50 patients were enrolled. The mean age was 61.86 years (range: 31–83 years). The population included 42 men (84%) and 8 women (16%), with a sex ratio of 5.25.
Patients with RV infarction showed significantly reduced conventional echocardiographic parameters of RV systolic function, along with impaired strain values, compared to those without RV involvement (Table 1).
A very strong, statistically significant positive correlation was observed between right ventricular free lateral wall strain (FWLS-RV) and RV infarction (r = 0.921, P = 0.001), suggesting its potential as a reliable marker of RV myocardial damage.
FWLS-RV also demonstrated significant correlations with traditional RV systolic function. A moderate correlation was found with RV fractional shortening (r = 0.471, P < 0.001), and a strong correlation with tricuspid annular plane systolic excursion (TAPSE) (r = 0.72, P < 0.001), supporting FWLS-RV as a sensitive marker of RV function.
Conclusion
RV strain analysis is a valuable echocardiographic parameter for detecting RV involvement in IMI. It correlates well with conventional measures of RV systolic function, thereby enhancing diagnostic accuracy and guiding targeted clinical care.
下段心肌梗死(IMI)通常由右冠状动脉闭塞引起,可扩展至右心室(RV),由于心输出量受损而增加发病率。由于临床体征和标准心电图变化往往缺乏诊断准确性,因此检测右心室受累仍然具有挑战性。目的评价左室应变分析在检测左室累及IMI患者中的作用,并评价其与常规超声心动图参数的相关性。方法本横断面观察研究在Charles Nicolle医院心内科进行。它包括在2022年1月至2024年12月期间因急性下壁心肌梗死而入住重症监护病房的患者。结果在24个月的研究期间,50例患者入组。平均年龄61.86岁(范围:31 ~ 83岁)。人口中男性42人(84%),女性8人(16%),性别比为5.25。与没有右心室受累的患者相比,右心室梗死患者右心室收缩功能的常规超声心动图参数显著降低,应变值也明显受损(表1)。右心室游离外壁应变(FWLS-RV)与右心室梗死呈极显著正相关(r = 0.921, P = 0.001),提示其有可能作为右心室心肌损伤的可靠标志。FWLS-RV与传统右心室收缩功能也有显著相关性。与右心室分数缩短有中度相关性(r = 0.471, P < 0.001),与三尖瓣环状平面收缩偏移(TAPSE)有强相关性(r = 0.72, P < 0.001),支持FWLS-RV作为右心室功能的敏感标志物。结论左室应变分析是检测左室累及IMI的超声心动图参数。它与常规右室收缩功能指标具有良好的相关性,从而提高了诊断的准确性,指导有针对性的临床护理。
