RESUMO

PURPOSE OF REVIEW: In this review, we outline the impacts of the COVID-19 pandemic on non-communicable diseases around the world. RECENT FINDINGS: The mechanisms of COVID-19's impact on non-communicable diseases are both direct and indirect. The direct mechanisms include direct vascular and myocardial injury as well as pancreatic injury increasing incidence of new-onset diabetes. Indirect effects of the pandemic on non-communicable disease include delayed presentation for acute illness including STEMI and the impact of social distancing and quarantine policies on socialization, mental health, physical activity, and the downstream health impacts of inactivity and deconditioning. International focus has been on disease variants, infection control and management, healthcare system, and resource utilization and infection incidence. However, the impact of this pandemic on non-communicable diseases has been largely overlooked but will manifest itself in the coming years to decades.

RESUMO

PURPOSE OF REVIEW: Media sources, such as the Internet, television, and social media, have become powerful communication tools that have transformed the way medical information is acquired across the world. RECENT FINDINGS: Over 40% of today's patients report that social media affects their healthcare decisions, and approximately 65% of healthcare professionals report using social media for professional activities. These enhanced communication tools have made a substantial impact on the widespread dissemination of medical information. However, as a consequence, popular media platforms have also become purveyors of medical misinformation. In this review, we propose a framework for clinicians on how to effectively and appropriately integrate medical information available via online resources including social media platforms into modern healthcare practices.

RESUMO

PURPOSE OF REVIEW: Omega-3 fatty acids (ω-3 FA) are among the most well-recognized health supplements but their cardiovascular benefits have long been controversial owing to inconsistent results from previous cardiovascular outcomes trials (CVOT). In this article, we provide a short review of existing literature followed by recent randomized clinical trial data, with a discussion of the potential clinical implications of these new findings. RECENT FINDINGS: Data from the randomized, controlled trial REDUCE-IT, when viewed within the context of other recently published trials ASCEND and VITAL, add to a growing body of evidence on the use of ω-3 FA therapies in the treatment of atherosclerotic cardiovascular disease (ASCVD). Given the different formulations, dosages, and patient populations studied, CVOTs of ω-3 FA have provided valuable insight into the use of these agents in cardioprotection. Current data suggest that higher dosages of pure eicosapentaenoic acid ω-3 FA formulations provide additional benefit in reduction of ASCVD events.

RESUMO

BACKGROUND: Outcomes with bivalirudin compare favorably with heparin ± GPIIb/IIIa receptor inhibition (heparin ± GPI) during percutaneous coronary intervention (PCI). Patients with congestive heart failure (CHF) have increased risk for complications. The objective was to investigate clinical and economic outcomes for bivalirudin ± GPI vs. heparin ± GPI among PCI patients with CHF. METHODS: Using the Premier Hospital Database, PCI patients with CHF were stratified by anticoagulant: bivalirudin, bivalirudin ± GPI, heparin and heparin ± GPI. The probability of receiving bivalirudin ± GPI was estimated using individual and hospital variables. Using propensity scores, each bivalirudin ± GPI patient was matched to a heparin ± GPI patient. The primary outcome was in-hospital death. Bleeding rates, transfusion, length of stay and in-hospital cost were ascertained. RESULTS: Overall, 116,313 patients at 315 hospitals received bivalirudin (n = 45,559) bivalirudin + GPI (n = 8,115), heparin (n = 27,972) or heparin + GPI (n = 34,667). Patients had STEMI (21.2%), NSTEMI (29.1%), unstable angina (16.6%), stable angina (5.7%) or other ischemic heart disease (24.2%). Of these, 79.1% of bivalirudin patients matched, resulting in 84,948 analyzed patients. Compared with heparin ± GPI patients, bivalirudin ± GPI patients had fewer deaths (3.3% vs. 3.9%; p < 0.0001), less clinically apparent bleeding (10.2% vs. 11.4%; p < 0.0001), clinically apparent bleeding with transfusion (2.7% vs. 3.2%, p <0.0001), and transfusion (8.5% vs. 9.8%, p < 0.0001). Patients receiving bivalirudin had shorter length of stay (6.3 vs. 6.8 days; p < 0.0001) and lower in-hospital cost (mean $26,706 vs. $27,166 [median $19,414 vs. $19,798]; p < 0.0001). In conclusion, this is the largest retrospective analysis of PCI patients with CHF and demonstrates bivalirudin ± GPI compared with heparin ± GPI is associated with lower inpatient rates of death, bleeding, and cost.

RESUMO

BACKGROUND: Lipoprotein(a) [Lp(a)] is an emerging risk factor for cardiovascular disease. Currently, there are few available therapies to lower Lp(a). We sought to evaluate the impact of AMG145, a monoclonal antibody against proprotein convertase subtilisin kexin type 9 (PCSK9), on Lp(a). METHODS AND RESULTS: As part of the LDL-C Assessment With PCSK9 Monoclonal Antibody Inhibition Combined With Statin Therapy (LAPLACE)-Thrombolysis in Myocardial Infarction (TIMI) 57 trial, 631 patients with hypercholesterolemia receiving statin therapy were randomized to receive AMG145 at 1 of 3 different doses every 2 weeks or 1 of 3 different doses every 4 weeks versus placebo. Lp(a) and other lipid parameters were measured at baseline and at week 12. Compared with placebo, AMG145 70 mg, 105 mg, and 140 mg every 2 weeks reduced Lp(a) at 12 weeks by 18%, 32%, and 32%, respectively (P<0.001 for each dose versus placebo). Likewise, AMG145 280 mg, 350 mg, and 420 mg every 4 weeks reduced Lp(a) by 18%, 23%, and 23%, respectively (P<0.001 for each dose versus placebo). The reduction in Lp(a) correlated with the reduction in low-density lipoprotein cholesterol (ρ=0.33, P<0.001). The effect of AMG145 on Lp(a) was consistent regardless of age, sex, race, history of diabetes mellitus, and background statin regimen. Patients with higher levels of Lp(a) at baseline had larger absolute reductions but comparatively smaller percent reductions in Lp(a) with AMG145 compared with those with lower baseline Lp(a) values. CONCLUSIONS: AMG145 significantly reduces Lp(a), by up to 32%, among subjects with hypercholesterolemia receiving statin therapy, offering an additional, complementary benefit beyond robust low-density lipoprotein cholesterol reduction with regard to a patient's atherogenic lipid profile.

RESUMO

BACKGROUND: We sought to evaluate the effect of potent platelet inhibition after acute coronary syndrome on total (ie, first and recurrent) occurrences of any of the primary outcome events (e.g., cardiovascular death, myocardial infarction, and stroke) as well as on other ischemic events, such as urgent revascularization, (severe) recurrent ischemia, transient ischemic attacks, and arterial thrombotic events. METHODS AND RESULTS: In the PLATelet inhibition and patient Outcomes (PLATO) study, 18 624 patients presenting with acute coronary syndromes randomly received ticagrelor (n=9333) or clopidogrel (n=9291). Cox proportional hazard models were used to calculate time to first event and hazard ratios. Total events were compared using a Poisson regression model, and time to second event or death was calculated with the Wei Lin Weissfeld method. Patients randomized to ticagrelor had 1057 total primary end point events versus 1225 for patients on clopidogrel (rate ratio, 0.86; 95% confidence interval, 0.79-0.93; P=0.003). The number of additional events was numerically lower for ticagrelor (189 versus 205; P=0.40), resulting in a hazard for time to second event/death of 0.80 (95% confidence interval, 0.70-0.90; P<0.001) and a number needed to treat of 54. For cardiovascular death/myocardial infarction/stroke/(severe) recurrent ischemia/transient ischemic attack/arterial thrombotic events, total events were fewer with ticagrelor (2030 versus 2290; rate ratio, 0.88; 95% confidence interval, 0.82-0.95; P<0.001), with fewer recurrent events with ticagrelor (740 versus 834; P=0.01) and a highly significant concurrent reduction in hazard for time to second event or death of 0.83 (95% confidence interval, 0.75-0.91; P<0.001). Recurrent PLATO major or Thrombolysis in Myocardial Infarction (TIMI) major non-coronary artery bypass graft bleeding events were infrequent and not different between the two therapies (P=0.96 and 0.38, respectively). CONCLUSIONS: In PLATO, treatment with ticagrelor compared with clopidogrel resulted in a reduction in total events, including first and subsequent recurrent cardiovascular events, when compared with clopidogrel. These types of analyses demonstrate an even greater absolute benefit of ticagrelor over clopidogrel than previously reported. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov/.

RESUMO

Following the publication of results from multiple landmark cardiovascular outcome trials of antihyperglycemic medications over the past 8 years, there has been a major shift in the focus of care for people with type 2 diabetes, from control of hyperglycemia to managing cardiovascular risk. Multiple international cardiology and diabetes society guidelines and recommendations now endorse sodium-glucose cotransporter-2 inhibitors and glucagon-like protein-1 receptor agonists as first-line therapies to mitigate cardiovascular risk. The most recent publication is the 2023 European Society of Cardiology guideline on the management of cardiovascular disease in those with type 2 diabetes that, for the first time, recommends use of both classes of medications for the mitigation of cardiovascular risk for those with or at high risk for atherosclerotic cardiovascular disease, heart failure, and chronic kidney disease. Here, we review the evidence behind contemporary society guidelines and recommendations for the management of type 2 diabetes and cardiovascular risk.

RESUMO

BACKGROUND: The 2023 Multisociety Guideline for the Management of Chronic Coronary Disease (CCD) updates recommendations for CCD, formerly known as "stable ischemic heart disease." This condition encompasses a spectrum of coronary vascular pathologies from subclinical to clinical ischemic heart disease. HYPOTHESIS: The new "ABC" mnemonic offers clinicians a streamlined framework for applying Class One Recommendations (COR1) and integrating recent updates into CCD management. METHODS: A critical analysis of the 2023 CCD guidelines was conducted, with this review highlighting key elements. RESULTS: The review outlines crucial changes, including novel recommendations supported by current clinical evidence. The focus is on these developments, clarifying their importance for day-to-day clinical practice. CONCLUSIONS: The review encourages a synergistic approach between primary healthcare providers and cardiologists to develop comprehensive strategies for lifestyle modification and medication therapy in CCD care. Furthermore, it suggests that utilizing comprehensive risk assessment tools can refine medical decision-making, ultimately enhancing patient care and clinical outcomes.

RESUMO

The 2023 American Heart Association/American College of Cardiology Multisociety Guideline for the Management of Patients with Chronic Coronary Disease provides updated recommendations for the management of chronic coronary disease. The term "chronic coronary disease" reflects the lifelong nature of the disease and diverse disease etiologies that come under the chronic coronary disease umbrella, beyond the presence of epicardial coronary stenosis, which require targeted lifestyle recommendations, serial optimization of medications, and involvement of multiple care team members. In this review, we highlight several areas where a collaborative approach between cardiologists, primary care clinicians, and internists is essential to optimize the care of patients with chronic coronary disease.

RESUMO

Cumulative exposure to low-density lipoprotein cholesterol (LDL-C) is a key driver of atherosclerotic cardiovascular disease (ASCVD) risk. An armamentarium of therapies to achieve robust and sustained reduction in LDL-C can reduce ASCVD risk. The gold standard for LDL-C assessment is ultracentrifugation but in routine clinical practice LDL-C is usually calculated and the most accurate calculation is the Martin/Hopkins equation. For primary prevention, consideration of estimated ASCVD risk frames decision making regarding use of statins and other therapies, and tools such as risk enhancing factors and coronary artery calcium enable tailoring of risk assessment and decision making. In patients with diabetes, lipid lowering therapy is recommended in most patients to reduce ASCVD risk with an opportunity to tailor therapy based on other risk factors. Patients with primary hypercholesterolemia and familial hypercholesterolemia (FH) with baseline LDL-C greater than or equal to 190 mg/dL are at elevated risk, and LDL-C lowering with high-intensity statin therapy is often combined with non-statin therapies to prevent ASCVD. Secondary prevention of ASCVD, including in patients with prior myocardial infarction or stroke, requires intensive lipid lowering therapy and lifestyle modification approaches. There is no established LDL-C level below which benefit ceases or safety concerns arise. When further LDL-C lowering is required beyond lifestyle modifications and statin therapy, additional medications include oral ezetimibe and bempedoic acid, or injectables such as PCSK9 monoclonal antibodies or siRNA therapy. A novel agent that acts independently of hepatic LDL receptors is evinacumab, which is approved for patients with homozygous FH. Other emerging agents are targeted at Lp(a) and CETP. In light of the expanding lipid treatment landscape, this manuscript reviews the importance of early, intensive, and sustained LDL-C-lowering for primary and secondary prevention of ASCVD.

RESUMO

BACKGROUND: LDL cholesterol (LDL-C) is a well established risk factor for cardiovascular disease. Proprotein convertase subtilisin/kexin type 9 (PCSK9) binds LDL receptors, targeting them for degradation. We therefore assessed the efficacy, safety, and tolerability of AMG 145, a human monoclonal IgG2 antibody against PCSK9, in stable patients with hypercholesterolemia on a statin. METHODS: In a phase 2, dose-ranging study done in 78 centres in the USA, Canada, Denmark, Hungary, and Czech Republic, patients (aged 18-80 years) with LDL-C greater than 2·2 mmol/L on a stable dose of statin (with or without ezetimibe), were randomly assigned equally, through an interactive voice response system, to subcutaneous injections of AMG 145 70 mg, 105 mg, or 140 mg, or matching placebo every 2 weeks; or subcutaneous injections of AMG 145 280 mg, 350 mg, or 420 mg, or matching placebo every 4 weeks. Everyone was masked to treatment assignment within the every 2 weeks and every 4 weeks schedules. The primary endpoint was the percentage change in LDL-C concentration from baseline after 12 weeks. Analysis was by modified intention to treat. This study is registered with ClinicalTrials.gov, number NCT01380730. FINDINGS: 631 patients with hypercholesterolaemia were randomly assigned to AMG 145 70 mg (n=79), 105 mg (n=79), or 140 mg (n=78), or matching placebo (n=78) every 2 weeks; or AMG 145 280 mg (n=79), 350 mg (n=79), and 420 mg (n=80), and matching placebo (n=79) every 4 weeks. At the end of the dosing interval at week 12, the mean LDL-C concentrations were reduced generally dose dependently by AMG 145 every 2 weeks (ranging from 41·8% to 66·1%; p<0·0001 for each dose vs placebo) and AMG 145 every 4 weeks (ranging from 41·8% to 50·3%; p<0·0001). No treatment-related serious adverse events occurred. The frequencies of treatment-related adverse events were similar in the AMG 145 and placebo groups (39 [8%] of 474 vs 11 [7%] of 155); none of these events were severe or life-threatening. INTERPRETATION: The results suggest that PCSK9 inhibition could be a new model in lipid management. Inhibition of PCSK9 warrants assessment in phase 3 clinical trials. FUNDING: Amgen.

RESUMO

OBJECTIVE: We investigated the prognostic performance of ST2 with respect to cardiovascular death (CVD) and heart failure (HF) in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) in a large multinational trial. BACKGROUND: Myocytes that are subjected to mechanical stress secrete ST2, a soluble interleukin-1 receptor family member that is associated with HF after STE-ACS. METHODS: We measured ST2 with a high-sensitivity assay in all available baseline samples (N=4426) in patients enrolled in the Metabolic Efficiency With Ranolazine for Less Ischemia in the Non-ST-Elevation Acute Coronary Syndrome Thrombolysis in Myocardial Infarction 36 (MERLIN-TIMI 36), a placebo-controlled trial of ranolazine in NSTE-ACS. All events, including cardiovascular death and new or worsening HF, were adjudicated by an independent events committee. RESULTS: Patients with ST2 concentrations in the top quartile (>35 µg/L) were more likely to be older and male and have diabetes and renal dysfunction. ST2 was only weakly correlated with troponin and B-type natriuretic peptide. High ST2 was associated with increased risk for CVD/HF at 30 days (6.6% vs 1.6%, P<0.0001) and 1 year (12.2% vs 5.2%, P<0.0001). The risk associated with ST2 was significant after adjustment for clinical covariates and biomarkers (adjusted hazard ratio CVD/HF 1.90, 95% CI 1.15-3.13 at 30 days, P=0.012; 1.51, 95% CI 1.15-1.98 at 1 year, P=0.003), with a significant integrated discrimination improvement (P<0.0001). No significant interaction was found between ST2 and ranolazine (Pinteraction=0.15). CONCLUSIONS: ST2 correlates weakly with biomarkers of acute injury and hemodynamic stress but is strongly associated with the risk of HF after NSTE-ACS. This biomarker and related pathway merit further investigation as potential therapeutic targets for patients with ACS at risk for cardiac remodeling.

RESUMO

AIMS: Prediabetes (PreDM) is a metabolically heterogeneous condition, differing in degree of insulin resistance and risk of type 2 diabetes mellitus and coronary heart disease (CHD). This study was initiated to evaluate the hypothesis that a fasting plasma triglyceride (TG) concentration ⩾1.7mmol/L can aid in identifying the subset of individuals with PreDM who are most insulin resistant and at greatest risk to develop CHD as well as type 2 diabetes mellitus. METHODS: In this cross-sectional study, measurements were made of: (1) steady-state plasma glucose (SSPG) concentration during the insulin suppression test to ascertain degree of insulin resistance and (2) conventional CHD risk factors in 587 apparently healthy individuals with normal fasting plasma glucose (NFG, n=370) or PreDM (n=217). RESULTS: Subjects with PreDM were significantly (P<0.001) more insulin resistant (higher SSPG concentrations) and had a more adverse CHD risk profile than those with NFG. A TG concentration ⩾1.7mmol/L identified a subset of individuals with PreDM (38%) who had a higher mean SSPG concentration (11.3±3.5mmol/L vs. 9.3±3.9mmol/L, P<0.001), were more likely to be insulin resistant (66% vs. 39%, P<0.001), and had a more adverse CHD risk factor profile. CONCLUSIONS: Measurement of fasting TG concentration in individuals with PreDM may provide a simple clinical approach to identify those who are insulin resistant, at enhanced risk of CHD, and more likely to develop type 2 diabetes mellitus.
