Myocarditis can lead to remodeling and fibrosis that can affect the heart's relaxation-lusitropy and chronotropic function. The current techniques for identifying myocarditis, such as endomyocardial biopsy and imaging, are costly, and intrusive. The current literature aims to identify reliable, accurate, and prognostically educative biomarkers of myocarditis. AREAS COVERED: This review covers the definition, clinical features, diagnostic markers, cardiac imaging, prognosis, and complications of myocarditis. PubMed, Embase, and the Cochrane data bank were searched from inception to 1 January 2024 for relevant articles. EXPERT OPINION: By adopting these diagnostic and prognostic biomarkers, clinicians can have a better comprehension of the progression of the disease and provide early diagnosis and treatment for myocarditis.

Achieving the right balance between bleeding and adequate protection from ischemic events remains an issue of debate and subject to ongoing investigation of various antithrombotic regimens and durations. AREAS COVERED: This review describes the landmark clinical trials comparing TAT to a period of dual antithrombotic therapy (DAT) and subsequent meta-analyses. It also describes the international recommendations that have been derived from this evidence and identifies outstanding issues that could be addressed in upcoming or future trials. EXPERT OPINION: The current recommended default strategy of a short period of TAT with clopidogrel followed by the withdrawal of aspirin faces a challenge from the prospect of more consistent P2Y inhibition provided by ticagrelor and prasugrel. Ticagrelor monotherapy has already been trialed in patients after PCI without an indication for OAC. DAT with ticagrelor or prasugrel immediately post-procedure could emerge as a comparably safe and more efficacious regimen than one involving clopidogrel in the right setting.

Studies have shown that natto reduces the risk of cardiovascular disease (CVD) mortality due to its fibrinolytic and antithrombotic properties. A new field of studies also demonstrates that NK can mitigate molecular pathways related to inflammation and oxidative stress and can be considered an adjuvant strategy for use in many non-communicable diseases (NCDs). This paper is a narrative review of the literature. A search was conducted in PubMed and ScienceDirect up to July 2024. AREAS COVERED: This review discusses the possible effects of NK on mitigating the common complications of NCDs, such as inflammation and oxidative stress. In addition, it provides an update on the most addressed areas related to NK's fibrinolytic and antithrombotic activities. EXPERT OPINION: Due to the fibrinolytic and antithrombotic activity of nattokinase, and more recently added to the anti-inflammatory and antioxidant effects, this enzyme can be used as a new adjuvant therapeutic strategy to mitigate inflammation and oxidative stress in NCDs, including CVD.

The objective of thi...INTRODUCTION: The development of depression after myocardial infarction is associated with a 2- to 2.5-fold increased risk of all-cause mortality, cardiovascular mortality, and cardiovascular events. The objective of this study was to investigate, through a broad search of the literature, whether major depression is associated with worse psychiatric outcomes in middle-aged patients with myocardial ischemia. METHODS: An extensive search for studies on the association between major depression and myocardial ischemia was conducted in the PubMed, Embase, PsycINFO, and Web of Science databases. Randomized clinical trials of middle-aged patients with myocardial ischemia and concomitant depressive symptoms were included. RESULTS: The 14 articles included in this systematic review did not confirm an association between myocardial ischemia and depression with worse psychiatric outcomes in middle-aged patients. However, worse cardiovascular outcomes have been observed in patients with depression after myocardial infarction. CONCLUSIONS: The findings of this study suggest that major depression increases cardiovascular risk in patients after acute myocardial infarction, possibly because of a more pronounced increase in inflammatory markers. REGISTRATION: This systematic review was registered in the International Prospective Registry of Systematic Reviews (PROSPERO) under the number CRD: 511650.

Furtherm...INTRODUCTION: The body of evidence linking cardiorespiratory fitness (CRF) levels with the risk of atrial fibrillation (AF) and stroke - two interconnected cardiovascular conditions - is not entirely consistent. Furthermore, specific CRF thresholds beyond which the risk of AF or stroke might not decrease are not well defined. AREAS COVERED: This review summarizes research evidence on the role of CRF in the development of AF and stroke including dose-response relationships in general population participants, explores the biological mechanisms through which CRF may exert its effects, assesses the potential implications for clinical care and population health, identifies gaps in the current evidence, and suggest directions for future research. MEDLINE and Embase were searched from inception until July 2024 to identify observational longitudinal and interventional studies as well as systematic reviews and meta-analyses related to these study designs. EXPERT OPINION: In the general population, increasing levels of CRF, achieved through consistent physical activity, can significantly reduce the likelihood of developing AF and stroke. The findings also advocate for a tailored approach to exercise prescriptions, acknowledging the plateau in benefits for AF risk beyond certain CRF levels, while advocating for higher intensity or prolonged activity to further reduce stroke risk.

Patients with cardiogenic shock are at high risk for atrial and ventricular arrhythmias, particularly within the subset of patients with an overlap of cardiogenic shock and cardiac arrest. AREAS COVERED: This review article will explore the prevalence, definition, management, and outcomes of common arrhythmias in patients with cardiogenic shock. This review will describe the pathophysiology of arrhythmia in cardiogenic shock and the impact of inotropic agents on increased arrhythmogenicity. In addition to medical management, focused assessment of mechanical circulatory support, radiofrequency ablation, deep sedation, and stellate ganglion block will be provided. EXPERT OPINION: We will navigate the limited data and describe the prognostic impacts of arrhythmia. Finally, we will conclude the review with a discussion of prevention strategies, research limitations, and future research directions.

We aim to study the incidence and predictors of ACS in patients who underwent TMVR. RESEARCH DESIGN AND METHODS: We queried the U.S. National Readmission Database to identify all cases of TMVR from 2016 to 2019. We further evaluated the incidence of ACS and used multivariable logistic regression to determine independent predictors of ACS in this population. RESULTS: Among 3,742 patients who underwent TMVR, 264 (7.05%) developed ACS. Among ACS patients, 204 (77%) had non-ST-segment elevation ACS and 66 (25%) had ST-segment elevation ACS. Independent predictors of ACS were acute limb ischemia, cardiogenic shock, history of coronary artery disease (CAD), smoking, cardiac arrest, respiratory failure requiring mechanical ventilation, and acute kidney injury. In-hospital mortality among ACS was three times higher in ACS patients than without ACS (16.76% vs. 5.45%, p-value < 0.01). CONCLUSIONS: ACS is not an uncommon complication after TMVR. The occurrence of ACS after TMVR is associated with high in-hospital mortality, longer length of stay, and higher hospital charges. The strongest predictors of ACS in these patients are the development of acute limb ischemia, cardiogenic shock, and a history of CAD.

Gastroprotective agents like proton pump inhibitors (PPI) are often employed to mitigate this risk, despite potential competitive inhibition between P2Y12-receptor inhibitors, NOACs, and VKAs. While the interactions and clinical outcomes of PPIs and DAPT have been frequently explored in literature, not many studies have evaluated the same outcomes for triple therapy. AREAS COVERED: This comprehensive narrative review of three studies on PPIs and triple from the PubMed/MEDLINE database supplemented by 23 other relevant studies aims to use the available literature to analyze the potential interactions between PPIs and triple therapy while shedding light on their mechanisms, clinical implications, and areas for optimization. EXPERT OPINION: If triple therapy is indicated following PCI, then patients at high-risk for bleeding may benefit from transition to apixaban and a PPI to lower the risk of gastrointestinal bleeding. More research is needed to determine the role of PPIs in triple therapies in prevention of gastrointestinal bleeding or potentiation of other adverse outcomes.

Current guideline recommendations are quite liberal on measuring Lp(a) (Class IIa, Level C), and may lead to underuse among (interventional) cardiologists. AREAS COVERED: This case-based narrative review outlines four clinical cases of patients with elevated Lp(a) to illustrate its pathophysiological impact on coronary artery disease (CAD). The expert consensus statements from the American Heart Association (AHA) and European Atherosclerosis Society (EAS) served as the basis of this review. More recent publications, from 2023 to 2024, were accessed through the MEDLINE online library. EXPERT OPINION: We highlighted the importance of routine Lp(a) measurement in identifying patients at high risk for atherosclerosis, necessitating potent risk mitigation. Measuring Lp(a) helps clinicians identify which patients are at highest residual risk, who require potent pharmacological treatment and special attention during catheter interventions. As noninvasive and advanced intravascular imaging modalities evolve, future catheterization laboratories will integrate advanced imaging, diagnostics, and treatment, facilitating tailored patient care. Knowing Lp(a) levels is crucial in this context. While Lp(a)-lowering drugs are currently investigated in clinical trials, it is of paramount importance to know Lp(a) levels and strive toward aggressive management of other modifiable risk factors in patients with elevated Lp(a) and established symptomatic CAD being diagnosed or treated in catheterization laboratories.

Most hypertensive patients can be controlled with standard medication combinations, but some may not respond adequately to ≥3 or even to ≥5 antihypertensive agents. AREAS COVERED: In this review, we summarize the recent literature on difficult-to-treat hypertension identified by a Medline search, and we discuss the options for fourth line and subsequent therapy. EXPERT OPINION: It is essential to confirm resistant hypertension with out-of-office blood pressure measurements and to consider lifestyle factors, adherence to medication and secondary causes of hypertension. When true resistant hypertension is confirmed and blood pressure is not controlled with an optimal triple combination, preferably as a fixed dose combination tablet, spironolactone is usually recommended as the fourth medication. Comorbid conditions should be treated as appropriate with sodium-glucose-cotransporter 2 inhibitors, glucagon-like peptide-1 receptor agonists, sacubitril-valsartan or finerenone. Renal denervation appears to be a useful addition to overcome some of the problems of medication adherence. The endothelin antagonist aprocitentan may be a final option in some countries. Of the drugs in development, the RNA based therapeutics that inhibit angiotensinogen synthesis appear to be some of the most promising.

Catheter ablation is a successful rhythm control strategy in paroxysmal AF, but it has demonstrated dramatically lower AF-free survival rates in patients with persistent AF. In recent years, myriad novel rhythm control strategies have been developed, each with the promise of improved persistent AF ablation success. AREAS COVERED: This review discusses multiple novel techniques and approaches to persistent AF. Authors identified relevant papers by searching PubMed and Google Scholar databases and considered all papers identified, regardless of publication date. It begins by discussing recent advances in electrogram analysis that yielded improved AF-free survival following persistent AF catheter ablation. Next, it discusses several trials revealing the shortcomings of MRI in guiding persistent AF ablation. Finally, it discusses one nascent technique (Vein of Marshall ablation) and technology (AI-assisted electrogram analysis) who have shown promise in improving persistent AF ablation. EXPERT OPINION: In the authors' expert opinions, upcoming persistent AF ablations will utilize a stepwise approach of (1) ensuring PV isolation, (2) Vein of Marshall ablation and (3) AI-assisted ablation to optimize future persistent AF ablation outcomes. This approach systematically addresses arrhythmogenic sources beyond the pulmonary veins, the historical treatment target.

AREAS COVERED: Herein we detail: (1) the low rates of LDL-C goal attainment; (2) despite guidelines clearly outlining indications of use, there is suboptimal initiation, intensification, and persistence of lipid lowering therapy, especially combination therapy; (3) key clinician-related factors contributing to this gap include inconsistent risk assessments, clinical inertia, and barriers to health access; (4) LDL-C reduction is associated with reductions in risk for cardiovascular events. Increasing LDL-C goal attainment rates should be a high public health priority. EXPERT OPINION: There is an urgent need to rethink dyslipidemia management. Opportunities exist to overcome LDL-C goal attainment barriers, which necessitates a concerted effort from patients, clinicians, health systems, payors, pharmaceutical companies, and public health advocates. LDL-C measurement should be a performance metric for health systems. In addition, upfront use of combination therapy and polypill formulations should be encouraged. Engaging pharmacists to support drug therapy and adherence is crucial. Leveraging telehealth and electronic medical record (EMR) functionalities can enhance these efforts and ensure more effective implementation.

AREAS COVERED: Reliable and valid psychological assessment tools are reviewed, including those specifically designed for ICD patient populations. EXPERT OPINION: Psychological assessment, in combination with cardiologic standard of care, can help overcome many barriers associated with poor implantable cardioverter-defibrillator (ICD) management and related cardiovascular outcomes. Earlier identification and treatment of mood concerns in ICD patients has been shown to improve quality of life (QOL) and patient outcomes. At this time, however, logistical challenges and time restraints, in addition to knowledge of appropriate treatment plans or referral options, remain central barriers to providing integrated, patient-centered care. Ultimately, all cardiology clinics would benefit from a collaborative care team that includes a mental health consultant or in-house psychologists who can provide consultations or referral services. Additionally, all patients that come to the clinics should complete proactive screening measures as routine component of care to assess the presence of mood concerns to improve patient outcomes and aid in treatment planning.

While information on this selected group of patients is limited, closer inspection reveals that this is a challenging patient population with certain risk factors for IHCA following treatment of STEMI. AREAS COVERED: In this review article, strategies for prevention of IHCA post STEMI are reviewed, as well as best-practices for the care of STEMI patients post-IHCA. EXPERT OPINION: Early and successful reperfusion is key for the prevention of IHCA and has a significant impact on in-hospital mortality. A number of pharmacological treatments have also been studied that can impact the progression to IHCA. Development of cardiogenic shock post-STEMI increases mortality and raises the risk of cardiac arrest. The treatment of IHCA follows the ACLS algorithm with some notable exceptions.

With recently published pivotal trials and multiple cohort studies reporting new data, there is a need to re-calibrate available statistical evidence. METHODS: A systematic literature search was conducted across databases from inception till February 2023. Dichotomous outcomes were pooled using Odds Ratio (OR), while continuous outcomes were pooled using Standardized Mean Difference (SMD) along with 95% corresponding intervals (95% CIs). RESULTS: Data was included from 17 studies (7 RCTs, 10 cohorts, = 155,829). Use of CEPD was associated with significantly reduced odds of stroke (OR = 0.60, 95% CI = 0.43-0.85, = 0.003). There was no significant difference in disabling stroke ( = 0.25), non-disabling stroke ( = 0.72), and 30-day mortality ( = 0.10) between the two groups. There were no significant differences between the two groups for Diffusion-Weighted Magnetic Resonance Imaging (DW-MRI) findings, acute kidney injury, risk of pacemaker implantation life-threatening bleed, major bleed, minor bleed, worsening National Institute of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS) and vascular complications ( > 0.05). CONCLUSIONS: The use of CEPD during TAVR reduced the incidence of all-stroke ( = 0.003); however, there were no significant differences in any of the other pooled outcomes ( > 0.05). REGISTRATION: The protocol of this meta-analysis was registered with the Open Science framework [https://doi.org/10.17605/OSF.IO/7W564] before data acquisition was started.

Meta-analysis of the long-term outcomes from the first-generation Absorb bioresorbable vascular scaffold (BVS) showed that this period of excess risk ended at 3 years. Therefore, current attention has been focused on improving early outcomes by increasing the scaffold's tensile strength and reducing strut thickness. AREAS COVERED: This review summaries the lessons learned from the first-generation BRS. It updates the long-term clinical outcomes of trials evaluating the ABSORB BVS and metallic alloy-based BRS. In addition, it reviews the next-generation BRSs manufactured in Asia. EXPERT OPINION: Critical areas to improve the performance and safety of biodegradable scaffolds include further development in material science, surface modification, delivery systems, and long-term follow-up studies.

It is therefore important to explore factors that contribute to this, as perceived by health-care professionals (HCPs). RESEARCH DESIGN AND METHODS: This was a qualitative study using in-depth interviews that enrolled 18 HCPs (i.e. six each of physicians, physiotherapists, and nurses; mean experience in CR: 17.9 ± 11.8 yrs) working in cardiovascular care, and CR across private and government hospitals (both teaching and non-teaching) in India. RESULTS: The main challenges were related to lack of referrals, perceived lack of benefit from CR, poor infrastructure within hospitals and health systems, and differences in practice. The perceived inadequacies were lack of competencies in CR, limited task sharing strategies, and ineffective utilization of existing human resources. Devising strategies to improve awareness and competencies, facilitating task sharing, and remodeling holistic care with an active CR component may be beneficial to facilitate greater implementation of CR in India. CONCLUSIONS: Challenges, inadequacies, and solutions to implementing CR have been explored by involving various HCPs commonly involved in delivering CR across different health systems in a LMIC.

Accurate motion correction, image registration, and reconstruction are critical for high-quality imaging, but this can be technically challenging and has traditionally relied on expert manual processing. With accurate processing, there is a rich variety of clinical, stress, functional, and anatomic data that can be integrated to guide patient management. AREAS COVERED: PubMed and Google Scholar were reviewed for articles related to artificial intelligence in nuclear cardiology published between 2020 and 2024. We will outline the prominent roles for artificial intelligence (AI) solutions to provide motion correction, image registration, and reconstruction. We will review the role for AI in extracting anatomic data for hybrid MPI which is otherwise neglected. Lastly, we will discuss AI methods to integrate the wealth of data to improve disease diagnosis or risk stratification. EXPERT OPINION: There is growing evidence that AI will transform the performance of MPI by automating and improving on aspects of image acquisition and reconstruction. Physicians and researchers will need to understand the potential strengths of AI in order to benefit from the full clinical utility of MPI.

To address these needs, many technological advancements have been developed. Myval and the new generation Myval Octacor (Meril Life Sciences Pvt. Ltd) are novel balloon-expandable (BE) transcatheter heart valve (THV) systems designed for the treatment of severe aortic stenosis. AREAS COVERED: This review aims to illustrate the design features of these novel THVs and the main evidence from available studies. Furthermore, we provide evidence of these THVs' performance in challenging scenarios such as extra-large aortic annuli, bicuspid aortic valves, and valve-in-valve/valve-in-ring procedures. EXPERT OPINION: Myval and Myval Octacor have demonstrated comparable early safety and clinical efficacy to the leading contemporary THVs, exhibiting remarkably low rates of moderate to severe paravalvular leak (PVL) and permanent pacemaker implantation (PPI). The wide range of sizes offered by the Myval family may minimize the risk of under-/oversizing, potentially explaining the lower rates of the aforementioned phenomena. Moreover, the presence of both internal skirt and external reinforced cuff may also explain the low rate of moderate to severe PVL.
