The Current State of Coronary Revascularization: Coronary Artery Bypass Graft Surgery Versus Percutaneous Coronary Interventions.

PURPOSE OF REVIEW: The optimal revascularization strategy for coronary artery disease depends on various factors, such as disease complexity, patient characteristics, and preferences. Including a heart team in complex cases is crucial to ensure optimal outcomes. Decision-making between percutaneous coronary intervention and coronary artery bypass grafting must consider each patient's clinical profile and coronary anatomy. While current practice guidelines offer some insight into the optimal revascularization approach for the various phenotypes of coronary artery disease, the evidence to support either strategy continues to evolve and grow. Given the large amount of contemporary data on revascularization, this review aims to comprehensively summarize the literature on coronary artery bypass grafting and percutaneous coronary intervention in patients across the spectrum of coronary artery disease phenotypes. RECENT FINDINGS: Contemporary evidence suggests that for patients with triple vessel disease, coronary artery bypass grafting is preferred over percutaneous coronary intervention due to better long-term outcomes, including lower rates of death, myocardial infarction, and target vessel revascularization. Similarly, for patients with left main coronary artery disease, both percutaneous coronary intervention and coronary artery bypass grafting can be considered, as they have shown similar efficacy in terms of major adverse cardiac events, but there may be a slightly higher risk of death with percutaneous coronary intervention. For proximal left anterior descending artery disease, both percutaneous coronary intervention and coronary artery bypass grafting are viable options, but coronary artery bypass grafting has shown lower rates of repeat revascularization and better relief from angina. The Synergy Between PCI with Taxus and Cardiac Surgery score can help in decision-making by predicting the risk of adverse events and guiding the choice between percutaneous coronary intervention and coronary artery bypass grafting. European and American guidelines both agree with including a heart team that can develop and lay out individualized, optimal treatment options with respect for patient preferences. The debate between coronary artery bypass grafting versus percutaneous coronary intervention in multiple different scenarios will continue to develop as technology and techniques improve for both procedures. Risk factors, pre, peri, and post-procedural complications involved in both revascularization strategies will continue to be mitigated to optimize outcomes for those patients for which coronary artery bypass grafting or percutaneous coronary intervention provide ultimate benefit. Methods to avoid unnecessary revascularization continue to develop as well as percutaneous technology that may allow patients to avoid surgical intervention when possible. With such changes, revascularization guidelines for specific patient populations may change in the coming years, which can serve as a limitation of this time-dated review.

The premise, promise, and perils of artificial intelligence in critical care cardiology.

Artificial intelligence (AI) is an emerging technology with numerous healthcare applications. AI could prove particularly useful in the cardiac intensive care unit (CICU) where its capacity to analyze large datasets in real-time would assist clinicians in making more informed decisions. This systematic review aimed to explore current research on AI as it pertains to the CICU. A PRISMA search strategy was carried out to identify the pertinent literature on topics including vascular access, heart failure care, circulatory support, cardiogenic shock, ultrasound, and mechanical ventilation. Thirty-eight studies were included. Although AI is still in its early stages of development, this review illustrates its potential to yield numerous benefits in the CICU.

Human Papillomavirus as Non-Traditional Cardiovascular Risk Factors: Fact or Fiction? Part 1.

Human papillomavirus (HPV) is the most common sexually transmitted infection in the US and worldwide, with more than 42 million Americans infected with types of HPV that are known to cause disease. While the link between HPV and the development of a variety of cancers has been strongly established, recent literature has demonstrated a potential association between HPV and increased risk of cardiovascular disease. Nevertheless, despite plausible mechanisms for the development of cardiovascular disease with HPV infection, a causative relationship has yet to be firmly established, in part due to potential confounding risk factors between the two. In this 2-part series, we discuss the emerging relationship between HPV and cardiovascular disease. In part 1, we focus on the pathophysiology of HPV infection and potential mechanisms for the development of cardiovascular disease.

More than just teeth: How oral health can affect the heart.

Epidemiological evidence has revealed a potential relationship between periodontal disease and cardiovascular disease (CVD). Consensus regarding a link between these pathologies remains elusive, however, largely secondary to the considerable overlap between risk factors and comorbidities common to both disease processes. This review article aims to update the evidence for an association by summarizing the evidence for causality between periodontitis and comorbidities linked to CVD, including endocarditis, hypertension (HTN), atrial fibrillation (AF), coronary artery disease (CAD), diabetes mellitus (DM) and hyperlipidemia (HLD). This article additionally discusses the role for periodontal therapy to improved management of the comorbidities, with the larger goal of examining the value of periodontal therapy on reduction of CVD risk. In doing so, we endeavor to further the understanding of the commonality between periodontitis, and CVD.

National Trends, Mortality and Outcomes in Intravascular Imaging-Guided Versus Angiography-Guided Percutaneous Coronary Intervention in the United States.

Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have become increasingly utilized in patients undergoing percutaneous coronary intervention (PCI). Despite these purported advantages, prior reports regarding the use of IVUS and OCT have indicated that contemporary use of intravascular imaging remains low with significant regional variation. Here, we present the findings of an updated contemporary analysis regarding the use of IVUS/OCT guided PCI vs. angiography-guided PCI in the United States. We also evaluated in-hospital mortality and clinical outcomes between IVUS/OCT-guided PCI versus angiography-guided PCI-only over million patients in the United States. There has been a significant decrease in the number of PCIs performed, while there has been increasing in trend of IVUS/OCT-guided PCI over this period. Most importantly, we found that IVUS/OCT guided PCI were associated with better clinical outcomes in terms of in-hospital mortality, compare with angiography guided PCI.

Autoimmune Rheumatic Diseases and Outcomes Following Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis.

Autoimmune Rheumatic Diseases (AIRDs) are associated with increased cardiovascular mortality. However, the post-percutaneous coronary intervention (PCI) outcomes in this population present a research gap, given the limited and discordant findings in existing studies. We conducted a systematic review and meta-analysis to assess the relationship between AIRDs and clinical outcomes after PCI; 9 studies with 7,027,270 patients (126,914 with AIRD, 6,900,356 without AIRD) were included. The AIRD cohort was characterized by an older age, a predominantly female demographic, and a greater prevalence of hypertension and diabetes mellitus. Over a mean follow-up period of 4.6 ± 3.5 years, AIRD patients demonstrated significantly higher odds of all-cause mortality (odds ratio (OR) 1.45, 95% CI: 1.25-1.78, P < .001) and major adverse cardiovascular events (MACE) (OR 1.63, 95% CI: 1.01-2.62, P = .04) compared with non-AIRD patients. Sensitivity analysis using adjusted estimates, confirmed the higher all-cause mortality (hazard ratio 1.32, 95% CI: 1.05-1.64, P = .01). Patients with rheumatoid arthritis had a significantly elevated odds of all-cause mortality (OR 1.50, 95% CI: 1.27-1.77) and MACE (OR 1.18, 95% CI: 1.14-1.21). Our study demonstrated an association between AIRDs and suboptimal long-term outcomes post-PCI. Prospective studies are warranted to explore the risk factors of unfavorable prognoses in patients with AIRDs.

Coronary Microvascular Dysfunction: A Guide for Clinicians.

Dysfunction of the coronary microvasculature has become increasingly recognized as an important mechanism of myocardial ischemia in patients without obstructive coronary artery disease. The causes and management of coronary microvascular dysfunction remain poorly understood and are still largely based on extrapolation of epicardial coronary artery disease data. Quantification of myocardial blood flow and flow reserve have improved diagnosis, though important questions remain. In this review, we explain current understanding of the spectrum of pathophysiology of coronary microvascular dysfunction, summarize current diagnostic techniques to assess for coronary microvascular dysfunction, and appraise the limited data on management options specifically for patients with coronary microvascular dysfunction.

Pharmacotherapy for Coronary Artery Disease and Acute Coronary Syndrome in the Aging Population.

PURPOSE OF REVIEW: To provide a comprehensive summary of relevant studies and evidence concerning the utilization of different pharmacotherapeutic and revascularization strategies in managing coronary artery disease and acute coronary syndrome specifically in the older adult population. RECENT FINDINGS: Approximately 30% to 40% of hospitalized patients with acute coronary syndrome are older adults, among whom the majority of cardiovascular-related deaths occur. When compared to younger patients, these individuals generally experience inferior clinical outcomes. Most clinical trials assessing the efficacy and safety of various therapeutics have primarily enrolled patients under the age of 75, in addition to excluding those with geriatric complexities. In this review, we emphasize the need for a personalized and comprehensive approach to pharmacotherapy for coronary heart disease and acute coronary syndrome in older adults, considering concomitant geriatric syndromes and age-related factors to optimize treatment outcomes while minimizing potential risks and complications. In the realm of clinical practice, cardiovascular and geriatric risks are closely intertwined, with both being significant factors in determining treatments aimed at reducing negative outcomes and attaining health conditions most valued by older adults.

Structural and functional cardiac parameters across occupations: a cross-sectional study in differing work environments.

Previous investigations have highlighted notable variations in cardiovascular risk indicators associated with various professional categories. However, only a few studies have examined structural and functional cardiac parameters using echocardiography within distinct occupational groups. Hence, this study endeavored to assess cardiac structural and functional parameters in three additional occupations: firefighters (FFs), police officers (POs), and office workers (OWs). This prospective study encompassed 197 male participants (97 FFs, 54 POs, and 46 OWs) from Germany. All participants underwent 2D and Doppler echocardiography in resting conditions; standard parasternal and apical axis views were employed to evaluate structural (diastolic and systolic) and functional (systolic and diastolic function, and strain) cardiac parameters. All three occupational groups exhibited a tendency towards septal hypertrophy. Notably, OWs exhibited the largest diastolic interventricular septum diameter (IVSd), at 1.33 ± 0.25 cm. IVSd significantly varied between POs and OWs (p = 0.000) and between POs and FFs (p = 0.025). Additionally, during diastole a substantially larger left ventricular posterior wall diameter (LVPWd) was observed in OWs compared to FFs (p = 0.001) and POs (p = 0.013). The left ventricular diastolic cavity diameter (LVIDd) and the left ventricular systolic cavity diameter (LVIDs) were significantly higher in POs than they were in FFs (LVIDd: p = 0.001; LVIDs: p = 0.009), and the LVIDd was notably higher in FFs (p = 0.015) and POs compared to OWs (p = 0.000). FFs exhibited significantly better diastolic function, indicated by higher diastolic peak velocity ratios (MV E/A ratio) and E/E' ratios, compared to POs (E/A ratio: p = 0.025; E/E' ratio: p = 0.014). No significant difference in diastolic performance was found between OWs and FFs. Significantly higher E'(lateral) values were noted in POs compared to FFs (p = 0.003) and OWs (p = 0.004). Ejection fraction did not significantly differ among FFs, POs, and OWs (p > 0.6). The left ventricular mass (LV Mass) was notably higher in POs than it was in FFs (p = 0.039) and OWs (p = 0.033). Strain parameter differences were notably improved in two- (p = 0.006) and four-chamber (p = 0.018) views for FFs compared to POs. Concentric remodeling was the predominant change observed in all three occupational groups. Significant differences in the presence of various forms of hypertrophy were observed in FFs, POs, and OWs (exact Fisher test p-values: FFs vs. OWs = 0.021, POs vs. OWs = 0.002). OWs demonstrated notably higher rates of concentric remodeling than FFs did (71.77% vs. 47.9%). This study underscores disparities in both functional and structural parameters in diverse occupational groups. Larger prospective studies are warranted to investigate and delineate differences in structural and functional cardiac parameters across occupational groups, and to discern their associated effects and risks on the cardiovascular health of these distinct professional cohorts.

Role of Colchicine in Cardiovascular Disorders.

Inflammation has played a pivotal role in atherosclerosis and other cardiovascular disorders, prompting the exploration of anti-inflammatory therapies to improve cardiovascular outcomes. Colchicine, a well-established agent in conditions such as gout and familial Mediterranean fever, has emerged as a promising novel anti-inflammatory agent in the realm of cardiovascular diseases. Its ability to target both traditional risk factors and residual inflammatory risk marks a significant advancement in cardiovascular prevention strategies, indicating a new era in cardiovascular care. Landmark trials have supported the efficacy and safety of low-dose colchicine in reducing major adverse cardiovascular events when combined with standard therapies. In addition, its endorsement by major cardiovascular societies underscores its significance as the first targeted anti-inflammatory therapy for cardiovascular disease. However, careful monitoring for drug interactions and adverse effects, particularly on kidney and liver function, is essential for safe use. In this review, we aim to comprehensively summarize the mechanisms of action of colchicine, its molecular and biochemical targets in various cardiovascular conditions, and its pharmacokinetics, and delve deeply into the existing evidence on its safety and efficacy in the treatment of cardiovascular disorders, including coronary artery disease, pericarditis, atrial fibrillation, and heart failure.

Trends in Transcatheter Aortic Valve Implantation Utilization, Outcomes, and Healthcare Resource Use in Patients with Liver Cirrhosis: A Decade of Insights (2011-2020).

It is well known that individuals with liver cirrhosis are considered high risk for cardiac surgery, with an increased risk for morbidity and mortality as the liver disease progresses. In the last decade, there have been considerable advances in transcatheter aortic valve implantation (TAVI) as an alternative to surgical aortic valve replacement (SAVR) in individuals deemed to high risk for surgery. However, research surrounding TAVI in the setting of liver cirrhosis has not been as widely studied. In this national population-based cohort study, we evaluated the trends of mortality, complications, and healthcare utilization in liver cirrhotic patients undergoing TAVI, as well as analyze the basic demographics of these individuals. We found that from 2011-2020, the amount of TAVI procedures conducted in cirrhotic patients was increasing annually while the mortality, procedural complications, and healthcare utilization trends in these cirrhotic patients undergoing TAVI decreased. Overall, TAVI does seem to be a reasonable management for aortic stenosis patients with liver cirrhosis who need aortic valve replacement.

Revascularization Strategies for Acute and Chronic Mesenteric Ischemia: A Narrative Review.

Mesenteric ischemia is a challenging condition characterized by insufficient blood perfusion to the mesentery and, consequently, intestinal tissues that continues to perplex clinicians. Despite its low prevalence, the condition's variable clinical presentation and elusive radiographic diagnosis can delay life-saving interventions in the acute setting and deteriorate the quality of life of patients when left undiagnosed or misdiagnosed. PURPOSE: Review and summarize recent diagnostic updates and emergent intervention strategies for acute and chronic mesenteric ischemia. METHODS: A narrative review of all relevant studies from January 2022 through September 2023. RESULTS: A total of 11 studies from MEDLINE, supplemented with 44 studies from Google Scholar, were included in the review. CONCLUSIONS: Both acute and chronic mesenteric ischemia propose diagnostic and therapeutic challenges for interventionalists. Computed tomographic angiography remains the diagnostic modality of choice for both. Open surgical intervention remains the gold standard for acute mesenteric ischemia, while endovascular techniques are preferred for chronic mesenteric ischemia.

Opportunities and Limitations of Renal Denervation: Where Do We Stand?

Hypertension is a primary contributor to cardiovascular disease, and the leading risk factor for loss of quality adjusted life years. Up to 50% of the cases of hypertension in the United States remain uncontrolled. Additionally, 8%-18% of the hypertensive population have resistant hypertension; uncontrolled pressure despite 3 different antihypertensive agents. Recently, catheter-based percutaneous renal denervation emerged as a method for ablating renal sympathetic nerves for difficult-to-control hypertension. Initial randomized (non-sham) trials and registry analyses showed impressive benefit, but the first sham-controlled randomized controlled trial using monopolar radiofrequency ablation showed limited benefit. With refinement of techniques to include multipolar radiofrequency, ultrasound denervation, and direct ethanol injection, randomized controlled trials demonstrated significant blood pressure improvement, leading to US Food and Drug Administration approval of radiofrequency- and ultrasound-based denervation technologies. In this review article, we summarize the major randomized sham-controlled trials and societal guidelines regarding the efficacy and safety of renal artery denervation for the treatment of uncontrolled hypertension.
