Patients with acute myocardial infarction (AMI) and chronic kidney disease (CKD) are at high risk of contrast-induced nephropathy (CIN), which can subsequently worsen the overall prognosis. To evaluate the efficacy of spironolactone for CIN prevention, 410 patients with AMI and CKD receiving percutaneous coronary intervention (PCI) were retrospectively analyzed. Among them, 240 and 170 patients were enrolled in the standard treatment and spironolactone groups (spironolactone was administered 2 days before and 3 days after PCI), respectively...

To expand the scope of genomic editing, a C-to-G transversion-based editor called CGBE has been developed for precise single-nucleotide genomic editing. However, limited editing efficiency and product purity have hindered the development and application of CGBE. In this study, we introduced the Puromycin-Resistance Screening System, referred to as CGBE/ABE-PRSS, to select genetically modified cells via the ABE or CGBE editors. The CGBE/ABE-PRSS system significantly improves the enrichment efficiency of CGBE- or ABE-modified cells, showing enhancements of up to 59...

The term MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries) refers to myocardial infarction cases where coronary arteries exhibit less than 50% stenosis. MINOCA encompasses a diverse range of pathologies with varying etiologies. Diagnosis involves meeting acute myocardial infarction criteria and excluding other causes (myocarditis, takotsubo syndrome). Clinical features often resemble those of traditional myocardial infarction, but MINOCA patients tend to be younger and more frequently female...

This study aimed to explore the relationship between the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and hypersensitive C-reactive protein (hs-CRP) and the prognosis of acute myocardial infarction (AMI) patients after percutaneous coronary intervention (PCI) treatment. A total of 118 early-onset AMI patients who successfully received PCI (in the PCI group, blood samples were collected before PCI, 12, 24, 48 h after PCI, and 90 d follow-up period) and 52 AMI patients who received only cardioangiography (CAG) (in the CAG group, blood samples were collected before CAG, 12, 24, 48 h after CAG, and 90 d follow-up period)...

The superiority of drug-coated balloon (DCB) in treating small vessels, branching lesions, and high-risk bleeding lesions in coronary heart disease patients has been confirmed. However, its safety and efficacy in large vessels are still unclear. We aimed to investigate whether the efficacy of DCB in large vessels is not inferior to that of drug-eluting stent (DES). From November 2019 to April 2022, a total of 88 patients in our hospital who underwent coronary angiography for the first time and decided to receive DCB or DES treatment were selected...

The quantification of carotid plaque has been routinely used to predict cardiovascular risk in cardiovascular disease (CVD) and coronary artery disease (CAD). To determine how well carotid plaque features predict the likelihood of CAD and cardiovascular (CV) events using deep learning (DL) and compare against the machine learning (ML) paradigm. The participants in this study consisted of 459 individuals who had undergone coronary angiography, contrast-enhanced ultrasonography, and focused carotid B-mode ultrasound...

BACKGROUND: Positive remodeling is an integral part of the vascular adaptation process during the development of atherosclerosis, which can be detected by coronary computed tomography angiography (CTA). METHODS: A total of 426 patients who underwent both coronary CTA and optical coherence tomography (OCT) were included. Four machine learning (ML) models, gradient boosting machine (GBM), random forest (RF), deep learning (DL), and support vector machine (SVM), were employed to detect specific plaque features...

OBJECTIVE: Female sex is a risk factor for adverse events after endovascular aortic repair. Sex comparative early and mid term outcomes of fenestrated and branched endovascular aortic arch repair (f/b-Arch) are presented. METHODS: Single centre retrospective sex comparative analysis of consecutive patients managed with f/b-Arch according to STROBE. Primary outcomes were sex comparative technical success, mortality, and cerebrovascular morbidity at 30 days. Kaplan-Meier estimates were used for follow up outcomes...

Hybrid coronary revascularization (HCR) combines a minimally invasive surgical approach with percutaneous coronary intervention (PCI) for the treatment of multi-vessel coronary artery disease. Despite decades of use, widespread acceptance has been limited. In this review, we conduct a comparative assessment of HCR in relation to traditional coronary artery bypass graft surgery and multi-vessel PCI. While large scale randomized data is still lacking, numerous studies have demonstrated that HCR may offer benefits regarding resource utilization and short-term morbidity, while delivering comparable mid- and long-term survival compared to traditional bypass surgery...

Circulating calcitriol may contribute to the risk of cardiovascular disease (CVD), but its regulation in patients with CVD is poorly characterized. We therefore aimed to assess determinants of circulating calcitriol in these patients. We analyzed 2183 independent samples from a large cohort of patients scheduled for coronary angiography and 1727 independent samples from different other cohorts from patients with a wide range of CVDs, including heart transplant candidates, to quantify the association of different parameters with circulating calcitriol...

AIM: To evaluate the relationship of 25-hydroxyvitamin D (25(OH)D), lipoprotein-associated phospholipase A2 (Lp-PLA2), and coronary artery disease (CAD) in type 2 diabetes mellitus (T2DM) patients with no history or symptoms of cardiovascular disease. METHODS: The study identified 66 pairs of T2DM patients with and without CAD using propensity score matching. All subjects performed coronary computed tomography angiography (CCTA). Data on 25(OH)D, Lp-PLA2, and metabolic indexes were collected and analyzed...

Coronary artery dissection (CAD) is the intimal tearing of the coronary arterial wall and can be iatrogenic, spontaneous, or traumatic in origin. CAD is a rare but challenging condition that can cause significant hemodynamic compromise. Management strategies for CAD, such as the use of mechanical circulatory support devices, are available in the clinical setting. However, the incidence, etiology, and optimal management of CAD are not well-defined, emphasizing the need for adequate animal models in preclinical studies...

Acute myocardial infarction continues to account for a growing burden of heart failure worldwide. Despite existing therapies, new approaches for reducing the extent of damage and better managing heart failure progression are urgently needed. Preclinical large animal models are a critical step in the translation of scientific discoveries toward clinical trials and therapeutic application. In this chapter, we detail methods to induce swine models of myocardial infarction through catheter-mediated approaches involving either temporary (ischemia-reperfusion) or permanent (thrombus injection or embolic coil) occlusions...
