2023 AHA/ACC/ACCP/ASPC/NLA/PCNA Guideline for the Management of Patients With Chronic Coronary Disease: A Report of the American Heart Association/American College of Cardiology Joint Committee on Clinical Practice Guidelines.

AIM: The "2023 AHA/ACC/ACCP/ASPC/NLA/PCNA Guideline for the Management of Patients With Chronic Coronary Disease" provides an update to and consolidates new evidence since the "2012 ACCF/AHA/ACP/AATS/PCNA/SCAI/STS Guideline for the Diagnosis and Management of Patients With Stable Ischemic Heart Disease" and the corresponding "2014 ACC/AHA/AATS/PCNA/SCAI/STS Focused Update of the Guideline for the Diagnosis and Management of Patients With Stable Ischemic Heart Disease." METHODS: A comprehensive literature search was conducted from September 2021 to May 2022. Clinical studies, systematic reviews and meta-analyses, and other evidence conducted on human participants were identified that were published in English from MEDLINE (through PubMed), EMBASE, the Cochrane Library, Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline. STRUCTURE: This guideline provides an evidenced-based and patient-centered approach to management of patients with chronic coronary disease, considering social determinants of health and incorporating the principles of shared decision-making and team-based care. Relevant topics include general approaches to treatment decisions, guideline-directed management and therapy to reduce symptoms and future cardiovascular events, decision-making pertaining to revascularization in patients with chronic coronary disease, recommendations for management in special populations, patient follow-up and monitoring, evidence gaps, and areas in need of future research. Where applicable, and based on availability of cost-effectiveness data, cost-value recommendations are also provided for clinicians. Many recommendations from previously published guidelines have been updated with new evidence, and new recommendations have been created when supported by published data.

Chrono-nutrition for hypertension.

Despite the advancement in blood pressure (BP) lowering medications, uncontrolled hypertension persists, underscoring a stagnation of effective clinical strategies. Novel and effective lifestyle therapies are needed to prevent and manage hypertension to mitigate future progression to cardiovascular and chronic kidney diseases. Chrono-nutrition, aligning the timing of eating with environmental cues and internal biological clocks, has emerged as a potential strategy to improve BP in high-risk populations. The aim of this review is to provide an overview of the circadian physiology of BP with an emphasis on renal and vascular circadian biology. The potential of Chrono-nutrition as a lifestyle intervention for hypertension is discussed and current evidence for the efficacy of time-restricted eating is presented.

Effect of pharmacist interventions on the management of overweight and obesity: A systematic review.

BACKGROUND: Pharmacists are underused healthcare professionals who are well positioned to provide weight management interventions; however, a systematic review of the literature supporting the role of pharmacists in weight management is lacking. OBJECTIVES: To conduct a systematic review to assess the body of evidence supporting the role of pharmacists in the management of obesity. METHODS: A literature search of OVID MEDLINE, Embase, Web of Science, and CINAHL was conducted from inception through February 23, 2023, to identify studies involving pharmacist interventions for weight management. Included studies were retrospective or prospective studies reporting a change in body weight, body mass index (BMI), or waist circumference as a primary endpoint; and a weight management intervention involving a pharmacist. Studies were excluded if they did not report the desired outcomes, involved pediatric populations, or lacked a pharmacist in the intervention. RESULTS: Twenty-nine studies met the eligibility criteria. A total of 6,423 study participants were enrolled with a mean BMI of 27 to 46 kg/m2. The included studies were conducted across 8 different countries with 15 from the United States. The primary approach was a prepost/quasi-experimental study design, typically conducted in community pharmacies. The pharmacists' role varied widely but mainly involved educational counseling as the pharmacist made medication recommendations in only 5 studies. Multidisciplinary collaboration was infrequent. All but 3 studies reported a significant improvement in the weight loss outcome of interest, although most study durations were less than 6 months. A critical appraisal of the 29 studies found the overall quality of the available studies to be relatively poor. CONCLUSION: Pharmacist interventions for weight management were mostly effective in reducing body weight; however, more robust clinical trials with a comparator group and for longer duration are warranted. The pharmacist's role in managing weight loss medications also requires further study.

Job satisfaction among board-certified pharmacists in Virginia.

BACKGROUND: Board certification has been associated with job satisfaction. Identifying factors influencing board-certified pharmacists' job satisfaction can assist employers in recruitment and retention. OBJECTIVES: To identify factors associated with job satisfaction among board-certified pharmacists in Virginia. METHODS: This cross-sectional study utilized data from the 2018 Virginia Pharmacy Workforce Survey and included pharmacists who held an active license in Virginia, were employed within the last year, and held any Board of Pharmacy Specialties certification. Descriptive statistics were used to summarize the data, and bivariate analyses compared job satisfaction across demographics and practice characteristics. Multivariable logistic regression identified factors associated with job satisfaction. RESULTS: Of 15,424 licensed pharmacists, 13,962 completed the survey (90.5%), while 1,284 (9.2%) met the inclusion criteria. Respondents were primarily female (69.4%) with a mean (SD) of 10.5 (9.6) years of work experience. Pharmacists predominantly held one full-time position (81.5%), earned an annual income between $100,000-$149,999 (77.0%), and worked in inpatient health systems (43.9%). Most board-certified pharmacists (93.7%) reported being very/somewhat satisfied with their current job. Job satisfaction was associated with work setting, primary hours worked per week, and paid sick leave benefits in bivariate analyses. In the multivariable logistic regression model, pharmacists working 30-49 versus ≥50 h/wk in their primary job (aOR= 2.91, 95% CI 1.63, 5.20), earning ≥$150,000 versus $100,000-$149,999 (aOR=4.60, 95% CI 1.21, 17.46), and with paid sick leave benefits (aOR= 1.92, 95% CI 1.19, 3.10) were more likely to report higher job satisfaction. Additionally, working in academia (aOR= 5.36, 95% CI 1.45, 19.85), inpatient health system (aOR= 3.13, 95% CI 1.41, 6.94), and outpatient health system (aOR= 4.07, 95% CI 1.33, 12.51) were associated with job satisfaction. CONCLUSION: Board-certified pharmacists in Virginia reported high job satisfaction. Primary hours worked per week, income, paid sick leave, and work setting were positively associated with job satisfaction.

Comparison of Safety and Biological Efficacy of Anakinra (Kineret) Dispensed in Polycarbonate Plastic versus Borosilicate Glass Syringes: A Patient-Level Analysis of VCUART2 and VCUART3 Clinical Trials.

Anakinra is a recombinant human interleukin-1 receptor antagonist approved for the treatment of inflammatory diseases. Kineret is available as a solution prepared in a borosilicate glass syringe. For implementing a placebo-controlled double-blind randomized clinical trial, anakinra is commonly transferred into plastic syringes. However, there is limited data on anakinra's stability in polycarbonate syringes. We described the results of our previous studies on the use of anakinra in glass (VCUART3) versus plastic syringes (VCUART2) compared with placebo. These studies were conducted in patients with ST-segment elevation myocardial infarction (STEMI), and we assessed the anti-inflammatory effects of anakinra versus placebo by comparing the area under the curve for high-sensitivity cardiac reactive protein (AUC-CRP) levels during the first 14 days of STEMI, its clinical effects on heart failure (HF) hospitalization, cardiovascular death, or new diagnosis of HF as well as adverse events profile between groups. The levels of AUC-CRP were 75 (50-255 mg·day/l) for anakinra in plastic syringes versus 255 (116-592 mg·day/l) in placebo and 60 (24-139 mg·day/l) and 86 (43-123 mg·day/l) for anakinra once and twice daily in glass syringes, respectively, compared with placebo 214 (131-394 mg·day/l). The rate of adverse events was also comparable between groups. There were no differences in the rate of HF hospitalization or cardiovascular death in patients who received anakinra in plastic or glass syringes. Fewer cases of new-onset heart failure occurred in patients receiving anakinra in plastic or glass syringes compared with placebo. Anakinra stored in plastic (polycarbonate) syringes provides comparable biologic and clinical effect to glass (borosilicate) syringes. SIGNIFICANCE STATEMENT: Anakinra (Kineret) 100 mg administered subcutaneously in patients with ST-segment elevation myocardial infarction (STEMI) for a duration of up to 14 days appears to have comparable safety and biological efficacy signals when delivered in prefilled glass or transferred into plastic polycarbonate syringes. This may have important implications for the feasibility of designing clinical trials in STEMI and other clinical conditions.

ACE-Inhibitors in Hypertension: A Historical Perspective and Current Insights.

PURPOSE OF REVIEW: This review describes the discovery and development of ACE inhibitors as antihypertensive agents, compares their efficacy, tolerability, and safety to ARBs, and highlights the contemporary issues surrounding ACE inhibitor use for HTN. RECENT FINDINGS: Angiotensin-converting enzyme (ACE) inhibitors are commonly prescribed medications for the management of hypertension (HTN) and other chronic conditions including heart failure and chronic kidney disease. These agents inhibit ACE, the enzyme that is responsible for converting angiotensin (AT) I to AT II. Inhibiting the synthesis of AT II causes arterial and venous vasodilation, natriuresis, and a decrease in sympathetic activity, resulting in the reduction of blood pressure. ACE inhibitors are first-line therapy in HTN management along with thiazide diuretics, calcium channel blockers, and angiotensin receptor blockers (ARB). Along with inhibiting AT II synthesis, inhibition of ACE causes accumulation of bradykinin, increasing the risk of bradykinin-mediated side effects like angioedema and cough. Since ARBs do not work on ACE in the renin-angiotensin system, the risk of angioedema and cough are lower with ARBs. Recent evidence has also suggested ARBs may have neuroprotective effects compared to other antihypertensives, including ACE inhibitors; however, this warrants further study. Currently, ACE inhibitors and ARBs have an equal class of recommendation for first-line treatment for the management of HTN. Recent evidence has shown ARBs to be just as effective as ACE inhibitors for HTN but with improved tolerability.

Oncologists' responsibility, comfort, and knowledge managing hyperglycemia in patients with cancer undergoing chemotherapy: a cross sectional study.

PURPOSE: To assess oncologists' responsibility, comfort, and knowledge managing hyperglycemia in patients undergoing chemotherapy. METHODS: In this cross-sectional study, a questionnaire collected oncologists' perceptions about professionals responsible for managing hyperglycemia during chemotherapy; comfort (score range 12-120); and knowledge (score range 0-16). Descriptive statistics were calculated including Student t-tests and one-way ANOVA for mean score differences. Multivariable linear regression identified predictors of comfort and knowledge scores. RESULTS: Respondents (N = 229) were 67.7% men, 91.3% White and mean age 52.1 years. Oncologists perceived endocrinologists/diabetologists and primary care physicians as those responsible for managing hyperglycemia during chemotherapy, and most frequently referred to these clinicians. Reasons for referral included lack of time to manage hyperglycemia (62.4%), belief that patients would benefit from referral to an alternative provider clinician (54.1%), and not perceiving hyperglycemia management in their scope of practice (52.4%). The top-3 barriers to patient referral were long wait times for primary care (69.9%) and endocrinology (68.1%) visits, and patient's provider outside of the oncologist's institution (52.8%). The top-3 barriers to treating hyperglycemia were lack of knowledge about when to start insulin, how to adjust insulin, and what insulin type works best. Women (ß = 1.67, 95% CI: 0.16, 3.18) and oncologists in suburban areas (ß = 6.98, 95% CI: 2.53, 11.44) had higher comfort scores than their respective counterparts; oncologists working in practices with > 10 oncologists had lower comfort scores (ß = -2.75, 95% CI: -4.96, -0.53) than those in practices with ≤ 10. No significant predictors were identified for knowledge. CONCLUSION: Oncologists expected endocrinology or primary care clinicians to manage hyperglycemia during chemotherapy, but long wait times were among the top barriers cited when referring patients. New models that provide prompt and coordinated care are needed.

With Current Safety and Efficacy Data, Should Statins Be Made Available as Nonprescription Over-the-Counter Drugs?

PURPOSE OF REVIEW: Statins inhibit the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase in the liver and reduce atherosclerotic cardiovascular disease (ASCVD) risk by enhancing low-density lipoprotein (LDL) clearance from the circulation. In this review, we discuss their efficacy, safety, and real-world utilization to make a case for reclassifying statins as nonprescription over-the-counter drugs to improve access and availability with the overarching goal of increasing statin utilization in patients most likely to benefit from this class of therapy. RECENT FINDINGS: Statin efficacy for reducing risk in primary and secondary ASCVD prevention populations as well as their safety and tolerability has been thoroughly investigated in large-scale clinical trials over the past 3 decades. Despite the overwhelming scientific evidence, statins are underutilized even among those at the highest ASCVD risk. We propose a nuanced approach to use statins as nonprescription drugs that leverages a multi-disciplinary clinical model. It integrates lessons learned from experiences outside the USA with a proposed Food and Drug Administration rule change that allows nonprescription drug products with an additional condition for nonprescription use.

Select drug-drug interactions with colchicine and cardiovascular medications: A review.

Several randomized clinical trials have demonstrated the clinical utility of colchicine in the prevention and management of various cardiovascular conditions, including secondary prevention of atherosclerotic cardiovascular disease, acute and chronic pericarditis, and atrial fibrillation. As a result, it is reasonable to anticipate increased use of colchicine within the cardiovascular specialty. However, colchicine is metabolized by cytochrome P450 3A4 (CYP3A4) and a substrate of the efflux transporter, P-glycoprotein (P-gp), creating the potential for clinically significant drug-drug interactions (DDIs). Therefore, when colchicine is administered concomitantly with other cardiovascular agents that inhibit CYP3A4 or P-gp, there is an increased risk of significant DDIs, potentially leading to negative sequelae. This article summarizes the evidence supporting the use of colchicine for cardiovascular disease, describes the mechanisms behind DDIs with select cardiovascular medications, and provides suggestions regarding colchicine dosing and management of DDIs to minimize the risk of poor tolerability and colchicine toxicity.

Factors associated with antihypertensive monotherapy among US adults with treated hypertension and uncontrolled blood pressure overall and by race/ethnicity, National Health and Nutrition Examination Survey 2013-2018.

BACKGROUND: Treating hypertension with antihypertensive medications combinations, rather than one medication (ie, monotherapy), is underused in the United States, particularly in certain race/ethnic groups. Identifying factors associated with monotherapy use despite uncontrolled blood pressure (BP) overall and within race/ethnic groups may elucidate intervention targets in under-treated populations. METHODS: Cross-sectional analysis of National Health and Nutrition Examination Surveys (NHANES; 2013-2014 through 2017-2018). We included participants age ≥20 years with hypertension, taking at least one antihypertensive medication, and uncontrolled BP (systolic BP [SBP] ≥ 140 mmHg or diastolic BP [DBP] ≥ 90 mmHg). Demographic, clinical, and healthcare-access factors associated with antihypertensive monotherapy were determined using multivariable-adjusted Poisson regression. RESULTS: Among 1,597 participants with hypertension and uncontrolled BP, age- and sex- adjusted prevalence of monotherapy was 42.6% overall, 45.4% among non-Hispanic White, 31.9% among non-Hispanic Black, 39.6% among Hispanic, and 50.9% among non-Hispanic Asian adults. Overall, higher SBP was associated with higher monotherapy use, while older age, having a healthcare visit in the previous year, higher body mass index, and having heart failure were associated with lower monotherapy use. CONCLUSION: Clinical and healthcare-access factors, including a healthcare visit within the previous year and co-morbid conditions were associated with a higher likelihood of combination antihypertensive therapy.

Rationale and design of interleukin-1 blockade in recently decompensated heart failure (REDHART2): a randomized, double blind, placebo controlled, single center, phase 2 study.

BACKGROUND: Heart failure (HF) is a global leading cause of mortality despite implementation of guideline directed therapy which warrants a need for novel treatment strategies. Proof-of-concept clinical trials of anakinra, a recombinant human Interleukin-1 (IL-1) receptor antagonist, have shown promising results in patients with HF. METHOD: We designed a single center, randomized, placebo controlled, double-blind phase II randomized clinical trial. One hundred and two adult patients hospitalized within 2 weeks of discharge due to acute decompensated HF with reduced ejection fraction (HFrEF) and systemic inflammation (high sensitivity of C-reactive protein > 2 mg/L) will be randomized in 2:1 ratio to receive anakinra or placebo for 24 weeks. The primary objective is to determine the effect of anakinra on peak oxygen consumption (VO2) measured at cardiopulmonary exercise testing (CPX) after 24 weeks of treatment, with placebo-corrected changes in peak VO2 at CPX after 24 weeks (or longest available follow up). Secondary exploratory endpoints will assess the effects of anakinra on additional CPX parameters, structural and functional echocardiographic data, noninvasive hemodynamic, quality of life questionnaires, biomarkers, and HF outcomes. DISCUSSION: The current trial will assess the effects of IL-1 blockade with anakinra for 24 weeks on cardiorespiratory fitness in patients with recent hospitalization due to acute decompensated HFrEF. TRIAL REGISTRATION: The trial was registered prospectively with ClinicalTrials.gov on Jan 8, 2019, identifier NCT03797001.

Survey of CDC-recognized community pharmacies providing the National Diabetes Prevention Program and impact of the COVID-19 pandemic on program delivery.

BACKGROUND: The Centers for Disease Control and Prevention (CDC) established the National Diabetes Prevention Program (NDPP) to prevent type 2 diabetes using an evidence-based lifestyle intervention program provided by community- and health care-based organizations, including community pharmacies. OBJECTIVES: This study aimed to characterize CDC-recognized community pharmacies offering NDPP and determine the impact of the coronavirus disease 2019 (COVID-19) pandemic on program delivery. METHODS: A list of CDC-recognized community pharmacies offering NDPP was obtained from the CDC Registry of Recognized Programs on September 19, 2020. A 23-question cross-sectional survey was created to obtain information about program inception, delivery, recruitment, enrollment, program evaluation, reimbursement, and the impact of the COVID-19 pandemic. Each pharmacy was contacted via telephone using a standardized script and invited to complete the survey over the phone or online. A follow-up e-mail was then sent approximately 2 weeks later to pharmacies that had not responded. RESULTS: A total of 73 community pharmacies were identified in the CDC registry. Of the 64 eligible community pharmacies, 42% (n = 27) completed the survey. Most community pharmacies offering NDPP were in the Southeastern (41%) and Midwestern (22%) regions of the United States. A majority were independent pharmacies (78%) and had "pending" CDC recognition status (74%). Program delivery primarily occurred in the pharmacy (48%) or in a hybrid model (26%). Most programs were not submitting reimbursement claims (74%) and did not charge participants (82%). Nearly two-thirds of pharmacies (63%) strongly agreed that COVID-19 had significantly affected their programs, yet most (67%) continued to offer NDPP during the pandemic. CONCLUSION: To our knowledge, this is the first characterization of CDC-recognized community pharmacies providing NDPP. Best practices for implementing NDPP at community pharmacies warrant further exploration and models to ensure long-term sustainability. COVID-19 affected most community pharmacies providing NDPP, but the majority continued to offer NDPP during the pandemic.

Effect of Canagliflozin Compared With Sitagliptin on Serum Lipids in Patients with Type 2 Diabetes Mellitus and Heart Failure with Reduced Ejection Fraction: A Post-Hoc Analysis of the CANA-HF Study.

ABSTRACT: The sodium glucose co-transporter 2 inhibitors have demonstrated favorable effects on cardiovascular and renal disease; however, they may also increase low-density lipoprotein cholesterol (LDL-C). There are limited data directly comparing the effects of sodium glucose co-transporter 2inhibitors on serum lipids to other antihyperglycemic therapies. In this post-hoc analysis of the CANA-HF trial, we sought to compare the effects of canagliflozin to sitagliptin in patients with type 2 diabetes mellitus (T2DM) and heart failure and reduced ejection fraction (HFrEF). The CANA-HF trial was a prospective, randomized controlled study that compared the effects of canagliflozin 100 mg daily to sitagliptin 100 mg daily on cardiorespiratory fitness in patients with HFrEF and T2DM. Of the 36 patients enrolled in CANA-HF, 35 patients had both baseline and 12-weeks serum lipids obtained via venipuncture. The change in LDL-C from baseline to 12 weeks was 5 (-12.5 to 19.5) mg/dL versus -8 (-19 to -1) mg/dL (P = 0.82) and triglyceride levels was -4 (-26 to 9) mg/dL and -10.5 (-50 to 29.3) mg/dL (P = 0.52) for canagliflozin and sitagliptin, respectively. No significant differences were found between canagliflozin and sitagliptin for total cholesterol, high-density lipoprotein cholesterol or non-HDL-C (P > 0.5 for all). These data suggest that compared with sitagliptin, canagliflozin may not increase LDL-C in patients with T2DM and HFrEF.

Time of eating and cardiorespiratory fitness in patients with heart failure with preserved ejection fraction and obesity.

BACKGROUND AND AIMS: Our objective was to examine the impact of caloric intake before or after the mean time of evening meal on cardiorespiratory fitness (CRF) in patients with heart failure with preserved ejection fraction (HFpEF) and obesity. METHODS AND RESULTS: Twelve patients with HFpEF and obesity completed a cardiorespiratory exercise test to measure CRF, defined as peak oxygen consumption (VO2). Three five-pass 24-h dietary recalls were performed for each participant and mean evening meal time was determined for each participant individually as well as the group. Participants were divided into those who ate before (Group I) and after (Group II) the mean time of evening meal, 7:25 PM. Peak VO2 and exercise time were significantly greater in Group II compared to Group I, moreover, delaying time of evening meal was associated with greater peak VO2. CONCLUSION: Caloric intake after the mean time of evening meal was associated with better CRF in patients with HFpEF and concomitant obesity. Later nutrient intake may help prevent fasting related stress associated with cardiac metabolic disturbances present in HFpEF. Based on these findings, prospective trials aimed at examining the effects of later evening meal times in patients with HFpEF and obesity are warranted.

Pharmacist-administered long-acting injectable PCSK9 service: A solution to improve patient access and adherence.

In 2015, 2 proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, alirocumab and evolocumab, were approved by Food and Drug Administration (FDA). Both therapies reduce low-density lipoprotein cholesterol (LDL-C) by approximately 60% and reduce atherosclerotic cardiovascular disease (ASCVD) risk in patients with established ASCVD when added to background statin therapy. The initial cost of these medications was approximately $15,000 per year, which made them largely cost-prohibitive for many patients and the overall health care system. In recent years, the cost of both agents has been reduced by 60%, and they are no longer only available through specialty pharmacies. In addition, a third PCSK9-modulating therapy, inclisiran, is nearing FDA approval. Ongoing inclisiran therapy only requires biannual subcutaneous administration and achieves LDL-C reductions of approximately 50%. As the use of PCSK9-modulating therapies increases, models that improve adherence and persistence over time will be critical to ensure patient access and maximize their value. Community pharmacists can play an important role helping patients not only obtain access to these therapies by navigating previous authorization requests but also adhere to therapy by offering administration. Community pharmacists can also provide therapeutic monitoring using point-of-care lipid testing to ensure efficacy over time. Such a service could potentially be sustained through reimbursement for administration and point-of-care lipid testing. Given the cost of these therapies, innovative models involving community pharmacists will be necessary to ensure patient access to these preventive therapies and minimize overall costs to the health care system.

Patiromer and Sodium Zirconium Cyclosilicate in Treatment of Hyperkalemia: A Systematic Review and Meta-Analysis.

BACKGROUND: Patiromer and sodium zirconium cyclosilicate (SZC) are newer options for hyperkalemia treatment. This systematic review and meta-analysis were conducted to assess the safety and side effect profile of patiromer and SZC compared with placebo or other standards of care in the management of hyperkalemia. METHODS: We searched electronic databases for relevant articles. The screening was performed independently and data were extracted among the selected studies. We performed a statistical analysis on Revman 5.4 software. The odds ratio (OR) was used for outcome estimation with a 95% CI. RESULTS: Patiromer had lower rates of hyperkalemia (OR = 0.44; 95% CI, 0.22-0.89) compared with standard of care. The analysis showed no significant differences between the 2 groups in terms of overall adverse effects, any serious/specific adverse effects, or treatment discontinuation as a result of adverse effects. Comparing the SZC-10 group with standard of care showed no significant differences in the occurrence of hyperkalemia during treatment, overall adverse effects, any serious/specific adverse effects, or treatment discontinuation as a result of adverse effects but showed a higher rate of edema in the treatment group (OR = 6.77; 95% CI, 1.03-44.25). Similarly, no significant differences were seen between the 2 SZC doses for the occurrence of any adverse effects, hyperkalemia, constipation, diarrhea, or urinary tract infection, whereas edema was higher among patients receiving SZC-10 (OR = 3.13; 95% CI, 1.19-8.27). CONCLUSIONS: In patients with acute hyperkalemia, SZC is the drug of choice due to its more rapid reduction of serum potassium level, whereas in patients with chronic hyperkalemia, patiromer appears to be the drug of choice because SZC is associated with an increase in edema, likely due to an increase in sodium absorption, which could have important adverse consequences in patients with chronic kidney disease and or heart failure. Thus, both drugs were found to be safe while treating hyperkalemia. (Curr Ther Res Clin Exp. 2021; 82:XXX-XXX).

The effects of canagliflozin compared to sitagliptin on cardiorespiratory fitness in type 2 diabetes mellitus and heart failure with reduced ejection fraction: The CANA-HF study.

BACKGROUND: Canagliflozin reduces hospitalizations for heart failure (HF) in type 2 diabetes mellitus (T2DM). Its effect on cardiorespiratory fitness and cardiac function in patients with established HF with reduced ejection fraction (HFrEF) is unknown. METHODS: We conducted a double-blind randomized controlled trial of canagliflozin 100 mg or sitagliptin 100 mg daily for 12 weeks in 88 patients, and measured peak oxygen consumption (VO2 ) and minute ventilation/carbon dioxide production (VE/VCO2 ) slope (co-primary endpoints for repeated measure ANOVA time_x_group interaction), lean peak VO2 , ventilatory anaerobic threshold (VAT), cardiac function and quality of life (ie, Minnesota Living with Heart Failure Questionnaire [MLHFQ]), at baseline and 12-week follow-up. RESULTS: The study was terminated early due to the new guidelines recommending canagliflozin over sitagliptin in HF: 17 patients were assigned to canagliflozin and 19 to sitagliptin, total of 36 patients. There were no significant changes in peak VO2 and VE/VCO2 slope between the two groups (P = .083 and P = .98, respectively). Canagliflozin improved lean peak VO2 (+2.4 mL kgLM-1 min-1 , P = .036), VAT (+1.5 mL kg-1 min-1 , P = .012) and VO2 matched for respiratory exchange ratio (+2.4 mL Kg-1 min-1 , P = .002) compared to sitagliptin. Canagliflozin also reduced MLHFQ score (-12.1, P = .018). CONCLUSIONS: In this small and short-term study of patients with T2DM and HFrEF, interrupted early after only 36 patients, canagliflozin did not improve the primary endpoints of peak VO2 or VE/VCO2 slope compared to sitagliptin, while showing favourable trends observed on several additional surrogate endpoints such as lean peak VO2 , VAT and quality of life.

Impact of Different Doses of Omega-3 Fatty Acids on Cardiovascular Outcomes: a Pairwise and Network Meta-analysis.

PURPOSE OF REVIEW: Omega-3 fatty acid (O3FA) supplementation has shown conflicting evidence regarding its benefit in cardiovascular events. We performed a pairwise and network meta-analysis to elucidate the benefit of different doses of O3FA supplementation in cardiovascular prevention. RECENT FINDINGS: Fourteen studies were identified providing data on 125,763 patients. A prespecified cut-off value of < 1 g per day was set for low-dose (LD) O3FA and > 1 g per day for high-dose (HD) O3FA. The efficacy outcomes of interest were total death, cardiac death, sudden cardiac death, myocardial infarction, stroke, coronary revascularization, unstable angina, and major vascular events. Safety outcomes of interest were bleeding, gastrointestinal disturbances, and atrial fibrillation events. HD treatment was associated with a lower risk of cardiac death (IRR 0.79, 95% CI [0.65-0.96], p = 0.03 versus control), myocardial infarction (0.71 [0.62-0.82], p < 0.0001 versus control and 0.79 [0.67-0.92], p = 0.003 versus LD), coronary revascularization (0.74 [0.66-0.83], p < 0.0001 versus control and 0.74 [0.66-0.84], p < 0.0001 versus LD), unstable angina (0.73 [0.62-0.86], p = 0.0001 versus control and 0.74 [0.62-0.89], p = 0.002 versus LD), and major vascular events (0.78 [0.71-0.85], p < 0.0001 versus control and 0.79 [0.72-0.88], p < 0.0001 versus LD). HD treatment was associated with increased risk for bleeding events (1.49 [1.2-1.84], p = 0.0002 versus control and 1.63 [1.16-2.3], p = 0.005 versus LD) and increased atrial fibrillation events compared to control (1.35 [1.1-1.66], p = 0.004). HD O3FA treatment was associated with lower cardiovascular events compared to LD and to control, but increased risk for bleeding and atrial fibrillation events.

PCSK9 Inhibitors in Secondary Prevention-An Opportunity for Personalized Therapy.

Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of death worldwide. Low-density lipoprotein cholesterol (LDL-C) is the primary cause of ASCVD and reducing LDL-C levels with statin therapy significantly reduces ASCVD risk; however, significant residual risk remains. Two monoclonal antibodies (mAbs), alirocumab and evolocumab, that target proprotein convertase subtilisin/kexin-type 9 (PCSK9), reduce LDL-C levels by up to 60% when used in combination with statins and significantly reduce the risk of recurrent ASCVD events in both stable secondary prevention and acute coronary syndrome populations. Prespecified analyses of recent randomized controlled trials have shed light on how best to prioritize these therapies to maximize their value in select high-risk groups. These data have also informed recent clinical practice guidelines and scientific statements resulting in an expanded role for PCSK9-mAbs compared with previous guidelines, albeit there are notable differences between these recommendations. Ongoing research is exploring the long-term safety of PCSK9-mAbs and their role in the acute setting and patients without prior myocardial infarction or stroke. Novel therapies that inhibit PCSK9 synthesis via small interfering RNA, such as inclisiran, are also in development and may reduce LDL-C levels similar to PCSK9-mAbs, but with less frequent administration. Nonetheless, the PCSK9-mAbs are a breakthrough therapy and warrant consideration in very high-risk patients who are most likely to benefit. Such a personalized approach can help to ensure cost-effectiveness and maximize their value.

Cardiovascular Considerations in Treating Patients With Coronavirus Disease 2019 (COVID-19).

A novel betacoronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread rapidly across the globe since December 2019. Coronavirus disease 2019 (COVID-19) has a significantly higher mortality rate than seasonal influenza and has disproportionately affected older adults, especially those with cardiovascular disease and related risk factors. Adverse cardiovascular sequelae, such as myocarditis, acute myocardial infarction, and heart failure, have been reported in patients with COVID-19. No established treatment is currently available; however, several therapies, including remdesivir, hydroxychloroquine and chloroquine, and interleukin (IL)-6 inhibitors, are being used off-label and evaluated in ongoing clinical trials. Considering these therapies are not familiar to cardiovascular clinicians managing these patients, this review describes the pharmacology of these therapies in the context of their use in patients with cardiovascular-related conditions.
