Future Cardiology

Leadless permanent pacemakers represent an important innovation in cardiac device developments. Although transvenous permanent pacemakers have become indispensable in managing bradyarrhythmia and saving numerous lives, the use of transvenous systems comes with notable risks tied to intravascular leads and subcutaneous pockets. This drawback has spurred the creation of leadless cardiac pacemakers. Within this analysis, we compile existing clinical literature and proceed to evaluate the efficacy and safety of the Micra Transcatheter Pacing System...

Aim: Limited knowledge exists on the pathophysiological cascade beyond serum lactate's association with myocardial injury. Method: Assessed the prognostic value of lactate index on periprocedural variables and its impact on 30-day major adverse cardiovascular events (MACE) in 300 prospective ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). Results: Significant correlations were observed between admission lactate and Killip class, periprocedural time intervals, postprocedure thrombolysis in myocardial infarction (TIMI) flow and myocardial blush grade (MBG; p < 0...

WHAT IS THIS STUDY ABOUT?: The EMPEROR-Preserved study looked at the effects of empagliflozin in participants with heart failure with a preserved ejection fraction (HFpEF). This is when the lower left part of the heart (left ventricle) squeezes normally or near normally but does not fill with enough blood between heartbeats. Therefore, not enough blood is pumped around the body. For this study, HFpEF was defined as a condition in which more than 40% of blood in the left ventricle was pumped around the body...

WHAT IS THIS SUMMARY ABOUT?: This summary describes a study of a new pill for treating chronic heart failure called empagliflozin (brand name Jardiance® ). The study is called EMPEROR-Preserved and was published in the New England Journal of Medicine . Chronic heart failure is a condition where the heart does not pump blood around the body properly. Heart failure causes symptoms such as shortness of breath, tiredness and build-up of too much water in the body (fluid retention). These symptoms often need hospital treatment and increase the risk of early death...

Percutaneous coronary intervention (PCI) has transformed the management of ST-elevation myocardial infarction (STEMI) due to a reduction in early mortality and need for repeat revascularization. However, the conventional revascularization strategy, combined with state-of-the-art anti-thrombotic and antiplatelet therapies, can still be associated with poor clinical outcome in some patients, because of reperfusion injury and microvascular obstruction (MVO) contributing to the infarct size. To address this important therapeutic need, a broad-range of device-based treatments have been introduced...

The heart is susceptible to proinflammatory and profibrotic responses after myocardial injury, leading to further worsening of cardiac dysfunction. Important developments in the management of heart failure with reduced ejection fraction have reduced morbidity and mortality; however, these therapies focus on optimizing cardiac function through hemodynamic and neurohormonal pathways and not by repairing the underlying cardiac injury. The potential of cell-based therapy to reverse cardiac injury has received substantial attention...

Recently, prognosis and survival of cancer patients has improved due to progression and refinement of cancer therapies; however, cardiovascular sequelae in this population augmented and now represent the second cause of death in oncological patients. Initially, the main issue was represented by heart failure and coronary artery disease, but a growing body of evidence has now shed light on the increased arrhythmic risk of this population, atrial fibrillation being the most frequently encountered. Awareness of arrhythmic complications of cancer and its treatments may help oncologists and cardiologists to develop targeted approaches for the management of arrhythmias in this population...

Aim: The study objectives were to explore how IC services could be optimized. Methods: We adopted multiple methods, including policy analysis, literature review and interviews. Results: The most prominent themes were medical devices and service integration and management. IC Consultant interviews suggest the need to balance supply and demand, implement standards of practice and establish centres of excellence...

The management of patients with suspected acute coronary syndrome, especially in prehospital settings, is challenging. This Special Report focuses on studies in emergency medical services concerning chest pain patients' triage and risk stratification. In addition, it emphasizes advancements in point-of-care cardiac troponin testing. These developments are compared with in-hospital guidelines, proposing an initial framework for a new acute care pathway. This pathway integrates a risk stratification tool with high-sensitivity cardiac troponin testing, aiming to deliver optimal care and collaboration within the acute care chain...

Aim: We assessed self-reported efficacy in cardiovascular prevention practice among internal medicine, family medicine, endocrinology and cardiology clinicians. Patients & methods: We emailed a 21-item questionnaire to 956 physicians, nurse practitioners, physician assistants and pharmacists. Results: 264 clinicians responded (median age: 39 years, 55% women, 47.9% specialists). Most expressed high self-efficacy in lifestyle counselling, prescribing statins, metformin, and aspirin in primary prevention, but low self-efficacy in managing specialized conditions like elevated lipoprotein(a)...

Aim: To investigate the incidence and prevalence rates of coronary artery disease (CAD) in women with and without rheumatoid arthritis (RA).

Oral anticoagulants, including warfarin and direct oral anticoagulants, are the standard of care for thrombosis prevention and treatment; however, concerns of bleeding often dictate treatment decisions. Inhibition of the intrinsic coagulation system via factor XIa may allow for selective inhibition of the coagulation cascade without significantly impacting hemostasis after injury. Asundexian is an oral small molecule factor XIa inhibitor that, via this novel mechanism, may prove to be a safe and effective option compared with available anticoagulants...

Climate change has a particularly detrimental effect on the cardiovascular system, which is highly vulnerable to harmful impacts. The accumulation of particulate matter (PM) and greenhouse gasses in the environment negatively impacts the cardiovascular system through several mechanisms. The burden of climate change-related diseases falls disproportionately on vulnerable populations, including the elderly, the poor, and those with pre-existing health conditions. A key component of addressing the complex interplay between climate change and cardiovascular diseases is acknowledging health disparities among vulnerable populations resulting from climate change, familiarizing themselves with strategies for adapting to changing conditions, educating patients about climate-related cardiovascular risks, and advocating for policies that promote cleaner environments and sustainable practices...
