A Comprehensive Review on the Electrocardiographic Manifestations of Cardiac Sarcoidosis: Patterns and Prognosis.

PURPOSE OF REVIEW: Cardiac sarcoidosis (CS) refers to cardiac involvement in sarcoidosis and is usually associated with worse outcomes. This comprehensive review aims to elucidate the electrocardiographic (ECG) signs and features associated with CS, as well as examine modern techniques and their importance in CS evaluation. RECENT FINDINGS: The exact pathogenesis of CS is still unclear, but it stems from an abnormal immunological response triggered by environmental factors in individuals with genetic predisposition. CS presents with non-cardiac symptoms; however, conduction system abnormalities are common in patients with CS. The most common electrocardiographic (ECG) signs include atrioventricular blocks and ventricular tachyarrhythmia. Distinct patterns, such as fragmented QRS complexes, T-wave alternans, and bundle branch blocks, are critical indicators of myocardial involvement. The application of advanced ECG techniques such as signal-averaged ECG, Holter monitoring, wavelet-transformed ECG, microvolt T-wave alternans, and artificial intelligence-supported analysis holds promising outcomes for opportune detection and monitoring of CS. Timely utilisation of inexpensive and readily available ECG possesses the potential to allow early detection and intervention for CS. The integration of artificial intelligence models into ECG analysis is a promising approach for improving the ECG diagnostic accuracy and further risk stratification of patients with CS.

Use of prostaglandin and cyclophosphamide for pediatric lupus with digital gangrene: Back to safety before hitting the axe!

Digital gangrene is a rare presenting feature of childhood lupus and only a reported incidence of 1.3%. We describe two cases of pediatric onset systemic lupus erythematosus (SLE), both 16 years old, presenting with digital gangrene and the successful salvage of the digits after using intravenous cyclophosphamide for immunosuppression and use of intravenous prostaglandin E1 infusions for limb reperfusion. Both of the patients responded exceptionally to the infusions with resolution of gangrene and near-total preservation of the functionality of toes.

Clinical Outcomes With Once-Weekly Insulin Icodec Versus Once-Daily Insulin Glargine U100 in Insulin-Naïve and Previously Insulin-Treated Individuals With Type 2 Diabetes: A Meta-Analysis of Randomised Controlled Trials.

AIMS: The once-weekly insulin icodec, a new basal insulin analog, may positively support a reduction in injection frequency and improve adherence to therapy in type 2 diabetes (T2D). This study aimed to evaluate the safety and efficacy of insulin icodec compared with those of once-daily glargine U100. METHODS: A comprehensive literature search was conducted using PubMed/MEDLINE, Embase and the Cochrane Library from inception till September 2023. Data about clinical outcomes in both groups were extracted. Forest plots were generated using the random-effects model by pooling odds ratios (ORs) and mean differences (MDs). RESULTS: Five randomised controlled trials and 2019 individuals with T2DM were included. In the pooled analysis, time in range was significantly higher (MD = 4.35; 95% CI: 1.65 to 7.05; p = 0.002) in the icodec group than in the once-daily glargine group. The HbA1c levels were significantly reduced (MD = -0.13; 95% CI: -0.24 to -0.03; p = 0.02) in the weekly icodec group compared with those in the once-daily glargine group. The weight gain was significantly less in the glargine group than in the weekly icodec group (MD = 0.41; 95% CI: 0.04 to 0.78; p = 0.03); however, in the subgroup analysis, this change became statistically insignificant in both insulin-naïve and previously insulin-treated individuals. The results were comparable across two groups for fasting plasma glucose levels, hypoglycaemia alert (Level 1), clinically significant (Level 2) or severe hypoglycaemia (Level 3), and adverse events. CONCLUSION: Insulin icodec was associated with a reduction in glycated haemoglobin levels and higher time in range, with a similar safety profile as compared to insulin glargine U100. However, further evidence is still needed to reach a definitive conclusion.

Transcatheter Edge-to-Edge Repair in Valvular Heart Disease: A Comprehensive Exploration of Equipment, Efficacy, Gender, Racial, and Socioeconomic Disparities, and Future Prospects.

The 2 primary components of valvular heart disease are mitral regurgitation (MR) and tricuspid regurgitation (TR). Transcatheter edge-to-edge repair (TEER) is an advanced, minimally invasive procedure that has recently displayed encouraging outcomes in the treatment of these pathologies. TEER offers a nonsurgical alternative for individuals diagnosed with conditions deemed to be high-risk surgical candidates. Currently, the TEER procedure employs devices such as MitraCLIP and TriCLIP, as well as innovative PASCAL (transcatheter valve repair system used for mitral and tricuspid valve repair) and FORMA (repair system used for tricuspid valve repair) repair systems. In the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial enrolling 614 patients to test the efficacy of TEER in MR, a significant reduction in hospitalization due to heart failure was observed at 24 months in the MitraClip + guideline-directed medical therapy (GDMT) group (35.8%) than in the GDMT-alone group (67.9%), HR, 0.53; P < 0.001, lower rate of all-cause mortality at 29.1% compared with 46.1% (P < 0.001), lower risk of cerebrovascular events (P = 0.001), and lower mortality due to cardiovascular events (P < 0.001). In another trial, patients with moderate TR or greater than New York Heart Association Class II or higher underwent TEER using the TriClip for the management of TR. The outcomes were encouraging, with 86% of patients showing a reduction in TR severity of at least one grade. As the technology and research surrounding TEER continue to progress, a more extensive range of patients are expected to qualify for TEER procedures. Our comprehensive review sought to extensively explore the background, equipment used, effectiveness of MR and TR, potential side effects, future prospects, and ongoing trials associated with TEER. We further discuss the existing gender, racial, and socioeconomic disparities in the realm of TEER.

Precision medicine in Myocardial Infarction With Non-obstructive Coronary Disease (MINOCA): A comprehensive review.

Cardiovascular diseases, particularly myocardial infarction (MI), are a significant cause of mortality globally. Traditional MIs are commonly linked to substantial coronary artery blockage. However, a distinct subset of patients experience MI with non-obstructive coronary arteries, known as MINOCA. Imaging techniques, such as invasive coronary angiograms, are employed to diagnose MI or assess predisposition to one. Coronary angiograms help visualize vessel blockages; however, these blockages are absent in MINOCA cases, posing a diagnostic challenge. Precision medicine aims to introduce new diagnostic tools to assist in early diagnosis and further management of MINOCA. As percutaneous coronary intervention (PCI) does not benefit MINOCA patients, medical management tailored to the specific pathophysiological mechanism of MINOCA is employed. For example, if MINOCA is attributed to plaque disruption with or without plaque thrombus formation, the fundamental treatments may include statins, agents that modulate the renin-angiotensin system (RAS), and antiplatelet therapies. On the other hand, if coronary artery spasm is identified as the primary cause, essential intervention involves the use of calcium channel blockers. This approach has been previously utilized in patients with vasospastic angina and could be utilized in MINOCA, although research specific to MINOCA is ongoing. Therefore, the handling of MINOCA underscores the necessity for a tailored therapeutic strategy that corresponds to the underlying physiological mechanism responsible for the patient's clinical symptoms. Ongoing research initiatives are directed at expanding the availability of these treatments, uncovering new biomarkers, creating advanced diagnostic instruments, and establishing a more individualized approach for managing MINOCA patients.

The impact of chronic total occlusion in non-infarct related arteries on patient outcomes following percutaneous coronary intervention for STEMI superimposed with cardiogenic shock: A pilot systematic review and meta-analysis.

INTRODUCTION: Chronic total occlusion (CTO) is defined as a near-total blockage of a coronary artery and often occurs in arteries that are not directly responsible for the event, known as non-infarct-related arteries (NIRA). Cardiogenic shock (CS) is a complication of ST-elevated myocardial infarction (STEMI) that carries significant mortality. We performed a meta-analysis to find an association between mortality in patients undergoing PCI for STEMI that have superimposed CS, with the presence of CTO in the NIRA. MATERIALS AND METHODOLOGY: A comprehensive literature search was conducted using PubMed, EMBASE, Google Scholar and clinicaltrials.gov from inception till October 2023 to retrieve studies that compare the presence of CTO with the absence of CTO in NIRA in STEMI with CS patients undergoing PCI. The primary endpoint was 30-day mortality and the secondary endpoints were risk of all-cause mortality (ACM) and repeat myocardial infarction (MI). Forest plots were generated using the random effects model by pooling odds ratios (ORs) with a 95 % confidence interval. Statistical significance was set at p < 0.05. RESULTS: 5 observational studies with a total of 5186 patients (1031 with CTO in NIRA and 4155 with no CTO in NIRA) were included. The presence of CTO in NIRA was associated with higher odds of 30-day mortality [OR: 3.10; 95 % CI: 1.52, 6.32; p < 0.002], and ACM [OR: 2.37; 95 % CI: 1.83, 3.08; p < 0.00001]. The odds of repeat MI were comparable between the two groups [OR: 1.61, 95 % CI: 0.03, 74.36, p = 0.81]. CONCLUSIONS: The presence of CTO in the NIRA serves as an independent indicator of unfavorable clinical outcomes including increased risk of 30-day mortality and all-cause mortality. The risk of repeat MI was comparable between the two groups. Large-scale, multicenter trials are warranted to identify the most effective management approach for these patients.

Exploring Acute Kidney Injury Following Aortic Dissection: A Comprehensive Review of Machine Learning Models for Predicting Risk, Management Strategies, Complications, and Racial and Gender Disparities.

Both types of aortic dissection (AD), Stanford type A and type B, can result in complications such as acute kidney injury (AKI) and aortic rupture. Renal complications in AD arise from compromised renal perfusion affecting the renal arteries. Understanding the intricate connection between AD and AKI is crucial for navigating the complexities of tailored treatment and formulating specific management plans. Concerning machine learning models, in patients with type A aortic dissection, factors such as decreased platelet count on admission, increased D-dimer level, longer cardiopulmonary bypass duration, elevated white blood cell levels, the need for blood transfusion, longer aortic clamp time, extended surgery duration, advanced age, and an elevated body mass index were positively associated with the development of AKI. For the risk of AKI after type B aortic dissection, elevated Nt-pro brain natriuretic peptide, prolonged activated partial thromboplastin time, elevated admission systolic blood pressure, and a higher contrast agent requirement during operative repair were found to predict the risk. Male gender was associated with a higher risk of AKI, and nonwhite race was linked to a higher risk of AKI, a greater likelihood of requiring more urgent procedures, and lower levels of insurance coverage. The treatment of AKI following AD requires a multifaceted approach. Identifying and addressing the underlying cause, such as low blood pressure, renal artery involvement, or medication-induced injury, is crucial for effective management and preventing further kidney damage. Maintaining proper fluid balance is essential for improving renal perfusion, but careful monitoring is necessary to avoid complications. The evolving landscape of research, particularly in biomarkers and AI programs, reveals a promising role in predicting the risk for and managing AKI post-AD.

Comparison of Outcomes Between Right and Left Upper Extremity Access in Endovascular Aortic Repair for Patients with Thoracoabdominal and Abdominal Aortic Aneurysms: A Systematic Review and Meta-Analysis.

Traditionally, left-sided upper extremity (LUE) access has been preferred in patients undergoing endovascular aortic repair (EVAR) to manage aortic aneurysms and decrease the risk of cerebrovascular adverse events. Recently, right-sided upper extremity access (RUE) has gained popularity owing to its greater maneuverability and ergonomics. However, synthesized data comparing the safety and efficacy of RUE and LUE accesses are limited. A comprehensive literature search was conducted on various databases from inception to September 2023 to retrieve all studies that compared RUE and LUE access in EVAR. Data on stroke, 30-day mortality, technical success, access-site complications, total time required for fluoroscopy, and contrast agent requirement were extracted, pooled, and analyzed. Forest plots were generated using a random-effects model on review manager by pooling the risk ratios (RRs) and standard mean differences (SMDs). Ten observational studies with a total of 3994 patients were included in our analysis with 1186 patients in the RUE and 2808 patients in the LUE access groups. EVAR using RUE access was associated with a significantly lower amount of contrast agent requirement than the LUE access group [SMD, -0.23; 95% confidence interval (CI), -0.45 to -0.02; P = 0.03]. There was no significant difference between the 2 groups in terms of the risk of stroke (RR, 1.62; 95% CI, 0.81-3.22; P = 0.17), 30-day mortality (RR, 1.42; 95% CI, 0.50-4.06; P = 0.51), rate of technical success (RR, 0.98; 95% CI, 0.95-1.01; P = 0.18), risk of access-site complications (RR, 1.00; 95% CI, 0.72-1.39; P = 0.99), and total time required for fluoroscopy (SMD, 0.07; 95% CI, -0.39 to 0.26; P = 0.69). The use of RUE access in EVAR appears to be comparable to LUE access in terms of the risk of stroke, access-related complications, all-cause mortality, technical success rate, and fluoroscopy duration. The RUE group required a lower volume of contrast agent.

Safety and Outcomes with Direct Oral Anticoagulants Versus Vitamin-K Antagonists in Chronic Thromboembolic Pulmonary Hypertension: A Systematic Review, Meta-Analysis, and Meta-Regression.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a subtype of pulmonary hypertension characterized by organized thrombi inside the pulmonary vasculature, leading to an increase in pulmonary artery pressure. CTEPH is seen in about 3-4% of patients with acute pulmonary embolism and is associated with poor outcomes. Apart from surgical intervention, lifelong anticoagulation is the mainstay of CTEPH management. Traditionally, CTEPH is managed with vitamin-K antagonists (VKA); however, direct oral anticoagulants (DOACs) are recently gaining popularity. However, the current literature comparing DOACs versus VKAs in CTEPH has inconsistent results. An electronic search of the major bibliographic databases was performed to retrieve studies comparing DOACs versus VKAs in CTEPH patients. For dichotomous outcomes, the odds ratio (ORs) with 95% confidence intervals (CI) were pooled using the DerSimonian and Laird random-effects model to generate forest plots. Statistical significance was considered at P < 0.05. Ten studies were included with 3936 patients (1269 in the DOAC group and 2667 in the VKA group). Treatment with DOAC was associated with no statistically significant difference in the risk of all-cause mortality (OR, 0.78; 95% CI, 0.35-1.71; P < 0.53), venous thromboembolism (OR, 1.19; 95% CI, 0.59-2.40; P = 0.63), major bleeding (OR, 0.68; 95% CI, 0.38-1.22; P = 0.20), and clinically relevant nonmajor bleeding (OR, 1.22; 95% CI, 0.80-1.86; P = 0.37). Our analysis demonstrates that DOACs are noninferior to VKAs in terms of their safety and outcomes profile in CTEPH. Further trials are needed to evaluate more robust evidence and to compare additional outcomes.

Emergence of Artificial Intelligence and Machine Learning Models in Sudden Cardiac Arrest: A Comprehensive Review of Predictive Performance and Clinical Decision Support.

Sudden cardiac death/sudden cardiac arrest (SCD/SCA) is an increasingly prevalent cause of mortality globally, particularly in individuals with preexisting cardiac conditions. The ambiguous premortem warnings and the restricted interventional window related to SCD account for the complexity of the condition. Current reports suggest SCD to be accountable for 20% of all deaths hence accurately predicting SCD risk is an imminent concern. Traditional approaches for predicting SCA, particularly "track-and-trigger" warning systems have demonstrated considerable inadequacies, including low sensitivity, false alarms, decreased diagnostic liability, reliance on clinician involvement, and human errors. Artificial intelligence (AI) and machine learning (ML) models have demonstrated near-perfect accuracy in predicting SCA risk, allowing clinicians to intervene timely. Given the constraints of current diagnostics, exploring the benefits of AI and ML models in enhancing outcomes for SCA/SCD is imperative. This review article aims to investigate the efficacy of AI and ML models in predicting and managing SCD, particularly targeting accuracy in prediction.

Association between psoriasis and atrial fibrillation: A Systematic review and meta-analysis.

INTRODUCTION: Psoriasis is a prevalent inflammatory skin condition characterized by erythematous plaques with scaling. Recent research has demonstrated an increased risk of cardiovascular diseases in patients with psoriasis; however, current evidence on atrial fibrillation (AF) risk in psoriasis is limited. MATERIALS AND METHODS: A systematic literature search was performed on major bibliographic databases to retrieve studies that evaluated AF risk in patients with psoriasis. The DerSimonian and Laird random effects model was used to pool the hazard ratios (HR) with 95 % confidence intervals (CI). Subgroup analysis was conducted by dividing the patients into mild and severe psoriasis groups. Publication bias was assessed by visual inspection and Egger's regression test. Statistical significance was set at p < 0.05. RESULTS: Seven studies were included, with 10,974,668 participants (1,94,230 in the psoriasis group and 10,780,439 in the control group). Patients with psoriasis had a significantly higher risk of AF [Pooled HR: 1.28; 95 % CI: 1.20, 1.36; p < 0.00001]. In subgroup analysis, patients with severe psoriasis [HR: 1.32; 95 % CI: 1.23, 1.42; p < 0.00001] demonstrated a slightly higher risk of AF, although statistically insignificant (p = 0.17), than the mild psoriasis group [HR: 1.21; 95 % CI: 1.10, 1.33; p < 0.0001]. Egger's regression test showed no statistically significant publication bias (p = 0.24). CONCLUSION: Our analysis demonstrated that patients with psoriasis are at a significantly higher risk of AF and hence should be closely monitored for AF. Further large-scale and multicenter randomized trials are warranted to validate the robustness of our findings.

A comprehensive exploration of novel biomarkers for the early diagnosis of aortic dissection.

Aortic dissection (AD) is a catastrophic life-threatening cardiovascular emergency with a 1-2% per hour mortality rate post-diagnosis, characterized physiologically by the separation of aortic wall layers. AD initially presents as intense pain that can then radiate to the back, arms, neck, or jaw along with neurological deficits like difficulty in speaking, and unilateral weakness in some patients. This spectrum of clinical features associated with AD is often confused with acute myocardial infarction, hence leading to a delay in AD diagnosis. Cardiac and vascular biomarkers are structural proteins and microRNAs circulating in the bloodstream that correlate to tissue damage and their levels become detectable even before symptom onset. Timely diagnosis of AD using biomarkers, in combination with advanced imaging diagnostics, will significantly improve prognosis by allowing earlier vascular interventions. This comprehensive review aims to investigate emerging biomarkers in the diagnosis of AD, as well as provide future directives for creating advanced diagnostic tools and imaging techniques.

A clearer vision: insights into juvenile idiopathic arthritis-associated uveitis.

The aim of this narrative review is to synthesize existing evidence-based knowledge on juvenile idiopathic arthritis-associated uveitis (JIA-U). We highlight epidemiology, pathophysiology, causes and genetics, risk factors, clinical features, diagnosis and screening, laboratory biomarkers, treatment options, trials with recent advances, and research challenges pertaining to JIA-U. The prevalence of JIA-U varies with different JIA subtypes, most frequently associated with the oligoarticular subtype. The risk factors involved in the development of JIA-U include younger age, antinuclear antibody (ANA) positivity, and the oligoarticular subtype of JIA, along with some specific major histocompatibility complex genes. Certain laboratory biomarkers, such as ANA, rheumatoid factor, interferon-λ, erythrocyte sedimentation rate, and transthyretin, have been used in JIA-U diagnosis, progress monitoring, and prognostication. Clinical features of JIA-U can range from asymptomatic to ophthalmic symptoms like redness, blurred vision, decreased visual acuity, hypopyon, and posterior uveitis, which can lead to retinal detachment and macular edema. The management protocol involves topical and systemic steroids, cycloplegics, disease-modifying antirheumatic drugs, biologic drugs, and surgical options. Early detection combined with prompt treatment is crucial to preventing irreversible vision loss in JIA-U.

The role of renal denervation in cardiology and beyond: An updated comprehensive review and future directives.

Renal denervation (RDN) is a minimally invasive intervention performed by denervation of the nervous fibers in the renal plexus, which decreases sympathetic activity. These sympathetic nerves influence various physiological functions that regulate blood pressure (BP), including intravascular volume, electrolyte composition, and vascular tone. Although proven effective in some trials, controversial trials, such as the Controlled Trial of Renal Denervation for Resistant Hypertension (SYMPLICITY-HTN3), have demonstrated contradictory results for the effectiveness of RDN in resistant hypertension (HTN). In the treatment of HTN, individuals with primary HTN are expected to experience greater benefits compared to those with secondary HTN due to the diverse underlying causes of secondary HTN. Beyond its application for HTN, RDN has also found utility in addressing cardiac arrhythmias, such as atrial fibrillation, and managing cases of heart failure. Non-cardiogenic applications of RDN include reducing the intensity of obstructive sleep apnea (OSA), overcoming insulin resistance, and in chronic kidney disease (CKD) patients. This article aims to provide a comprehensive review of RDN and its uses in cardiology and beyond, along with providing future directions and perspectives.

Association Between Fluoroquinolones and Major Adverse Cardiovascular Events: A Systematic Review.

Fluoroquinolones (FQs) are routinely administered antibiotics that have demonstrated an increased propensity to cause major adverse cardiovascular events (MACE). We conducted a systematic review aimed to investigate the association between FQ usage and the risk of MACE. A comprehensive literature search was conducted using PubMed, Scopus, and the Cochrane Library from inception to September 2023 to retrieve studies comparing FQ administration with placebo and reporting the occurrence of MACE. Relevant studies that explored the occurrence of MACE, defined as "acute myocardial infarction, stroke, cardiovascular mortality, arrhythmia, or heart failure" with FQ usage were eligible for inclusion. Four studies with a total of 42,808 patients were included. Levofloxacin, moxifloxacin, and gatifloxacin were observed to have an increased propensity to cause MACE, particularly arrhythmias, whereas ciprofloxacin was associated with the lowest risk of causing MACE. Despite the methodological diversity in the included studies, this systematic review uncovered a consistent trend of heightened likelihood of MACE with FQ administration across studies, suggesting that elevated serum concentrations of some FQs may correlate with higher risks of MACE development. This systematic review emphasizes the need for cautious administration of FQs, particularly in patients with a preexisting cardiovascular condition. Routine cardiac monitoring using electrocardiograms is warranted for patients on high doses of FQs to preemptively detect the development of MACE, particularly arrhythmias.

The role of exercise training and dietary sodium restriction in heart failure rehabilitation: A systematic review.

Heart failure (HF) rehabilitation seeks to enhance the entire well-being and quality of life of those with HF by focusing on both physical and mental health. Non-pharmacological measures, particularly exercise training, and dietary salt reduction, are essential components of heart failure rehabilitation. This study examines the impact of these components on the recovery of patients with heart failure. By conducting a comprehensive analysis of research articles published from 2010 to 2024, we examined seven relevant studies collected from sources that include PubMed and Cochrane reviews. Our findings indicate that engaging in physical activity leads to favorable modifications in the heart, including improved heart contractility, vasodilation, and cardiac output. These alterations enhance the delivery of oxygen to the peripheral tissues and reduce symptoms of heart failure, such as fatigue and difficulty breathing. Nevertheless, decreasing the consumption of salt in one's diet to less than 1500 mg per day did not have a substantial impact on the frequency of hospitalizations, visits to the emergency room, or overall mortality when compared to conventional treatment. The combination of sodium restriction and exercise training can have synergistic effects due to their complementary modes of action. Exercise improves cardiovascular health and skeletal muscle metabolism, while sodium restriction increases fluid balance and activates neurohormonal pathways. Therefore, the simultaneous usage of both applications may result in more significant enhancements in HF symptoms and clinical outcomes compared to using each program alone.

Optical coherence tomography-guided versus angiography-guided percutaneous coronary intervention: A meta-analysis of randomized controlled trials.

Background: Optical Coherence Tomography (OCT), a high-resolution imaging modality, guides stent implantation during percutaneous coronary intervention (PCI). However, OCT-guided PCI safety and efficacy data is limited. Methods: MEDLINE, Embase, and Cochrane Central were searched for randomized controlled trials (RCTs) comparing OCT-guided PCI to Angiography-guided PCI from inception to August 2023. A random-effects model was used to pool risk ratios (RRs), mean differences (MDs), and 95% confidence intervals (CIs) for clinical endpoints. Results: Our analysis included 5,139 patients from 11 studies. OCT-guided PCI resulted in a higher minimum stent area (MD = 0.35 [95 % CI, 0.21-0.49]; p < 0.00001), significantly reduced risk of cardiovascular mortality (RR = 0.56 [95 % CI, = 0.32-0.99]; p = 0.04), stent thrombosis (RR = 0.56 [95 % CI, 0.32-0.96]; p = 0.04), stent malapposition RR = 0.79 [95 % CI, 0.71-0.88]; p = < 0.0001) and major edge dissection (RR = 0.47 [95 % CI, 0.34-0.65]; p = <0.00001). However, no statistically significant difference was observed for all-cause mortality (RR = 0.71; p = 0.06), major adverse cardiovascular events (MACE) [RR = 0.80; p = 0.10], myocardial infarction (MI) [RR = 0.84; p = 0.16], target lesion revascularization (TLR) [RR = 0.94; p = 0.68], and target vessel revascularization (TVR) [RR = 0.91; p = 0.52]. Conclusion: OCT-guided PCI led to an increased MSA and decreased cardiovascular mortality, stent thrombosis, stent malapposition, and major edge dissection. The incidence of all-cause mortality, MACE, MI, TLR, and TVR remained comparable across the two groups.

Insights into calcific aortic valve stenosis: a comprehensive overview of the disease and advancing treatment strategies.

Aortic valve stenosis is a disease characterized by thickening and narrowing of the aortic valve (AV), most commonly due to calcification, which leads to left ventricular outflow obstruction called calcific aortic valve disease (CAVD). CAVD presents as a progressive clinical syndrome with cardiorespiratory symptoms, often with rapid deterioration. The modern-day pathophysiology of CAVD involves a complex interplay of genetic factors, chronic inflammation, lipid deposition, and valve calcification, with early CAVD stages resembling atherosclerosis. Various imaging modalities have been used to evaluate CAVD, with a recent trend of using advanced imaging to measure numerous AV parameters, such as peak jet velocity. Significant improvements in mortality have been achieved with transcatheter AV repair, but numerous therapeutics and modalities are being researched to delay the progression of CAVD. This article aims to provide a comprehensive review of CAVD, explore recent developments, and provide insights into future treatments with various novel modalities.

Anisodamine for the prevention of contrast-induced nephropathy in patients with acute coronary syndrome: a pilot systematic review and meta-analysis of randomized controlled trials.

Introduction: Contrast-induced nephropathy (CIN) is a common post-procedural complication of percutaneous coronary intervention for acute myocardial infarction (AMI). Anisodamine hydrobromide is an alkaloid that has demonstrated efficacy in improving microcirculation. This meta-analysis aims to evaluate the reno-protective effects of Anisodamine in patients undergoing percutaneous coronary intervention (PCI) for AMI. Methods: PubMed, Embase, Cochrane Library, Scopus, and clinicaltrials.gov were searched from inception to January 2024 for randomized controlled trials (RCTs) comparing the efficacy of Anisodamine in preventing the development of CIN. Outcomes of interest included the incidence of CIN, serum creatinine levels, and estimated glomerular filtration rate (eGFR). A random-effects model was used for pooling standard mean differences (SMDs) and odds ratios (ORs) with a 95% CI. Statistical significance was considered at a P less than 0.05. Results: Three RCTs involving 563 patients were included. Anisodamine was associated with a reduction in the incidence of CIN [OR: 0.44; 95% CI: 0.28, 0.69; P=0.0003], a reduction in serum creatinine levels at 48 [SMD: -6.78; 95% CI: -10.54,-3.02; P=0.0004] and 72 h [SMD: -6.74; 95% CI: -13.33,-0.15; P=0.03], and a higher eGFR at 24 [SMD: 5.77; 95% CI: 0.39, 11.14; P=0.03], and 48 h [SMD: 4.70; 95% CI: 2.03,7.38; P=0.0006]. The levels of serum creatinine at 24 h and eGFR value at 72 h were comparable between both groups. Conclusions: Anisodamine has demonstrated clinical efficacy in ameliorating the development of CIN post-PCI in AMI patients. Large, multi-centric RCTs are warranted to evaluate the robustness of these findings.

Pre- and post-surgery: advancements in artificial intelligence and machine learning models for enhancing patient management in infective endocarditis.

Infective endocarditis (IE) is a severe infection of the inner lining of the heart, known as the endocardium. It is characterized by a range of symptoms and has a complicated pattern of occurrence, leading to a significant number of deaths. IE poses significant diagnostic and treatment difficulties. This evaluation examines the utilization of artificial intelligence (AI) and machine learning (ML) models in addressing information extraction (IE) management. It focuses on the most recent advancements and possible applications. Through this paper, we observe that AI/ML can significantly enhance and outperform traditional diagnostic methods leading to more accurate risk stratification, personalized therapies as well and real-time monitoring facilities. For example, early postsurgical mortality prediction models like SYSUPMIE achieved 'very good' area under the curve (AUROC) values exceeding 0.81. Additionally, AI/ML has improved diagnostic accuracy for prosthetic valve endocarditis, with PET-ML models increasing sensitivity from 59% to 72% when integrated into ESC criteria and reaching a high specificity of 83%. Furthermore, inflammatory biomarkers such as IL-15 and CCL4 have been identified as predictive markers, showing 91% accuracy in forecasting mortality, and identifying high-risk patients with specific CRP, IL-15, and CCL4 levels. Even simpler ML models, like Naïve Bayes, demonstrated an excellent accuracy of 92.30% in death rate prediction following valvular surgery for IE patients. Furthermore, this review provides a vital assessment of the advantages and disadvantages of such AI/ML models, such as better-quality decision support approaches like adaptive response systems on one hand, and data privacy threats or ethical concerns on the other hand. In conclusion, Al and ML must continue, through multi-centric and validated research, to advance cardiovascular medicine, and overcome implementation challenges to boost patient outcomes and healthcare delivery.
