RESUMO

BACKGROUND: Regular physical activity (PA) is a component of cardiovascular health and is associated with a lower risk of cardiovascular disease (CVD). However, only about half of US adults achieved the current PA recommendations. OBJECTIVE: The study purpose was to implement PA counseling using a clinical decision support tool in a preventive cardiology clinic and to assess changes in CVD risk factors in a sample of patients enrolled over 12 weeks of PA monitoring. METHODS: This intervention, piloted for 1 year, had 3 components embedded in the electronic health record: assessment of patients' PA, an electronic prompt for providers to counsel patients reporting low PA, and patient monitoring using a Fitbit. Cardiovascular disease risk factors included PA (self-report and Fitbit), body mass index, blood pressure, lipids, and cardiorespiratory fitness assessed with the 6-minute walk test. Depression and quality of life were also assessed. Paired t tests assessed changes in CVD risk. RESULTS: The sample who enrolled in the remote patient monitoring (n = 59) were primarily female (51%), White adults (76%) with a mean age of 61.13 ± 11.6 years. Self-reported PA significantly improved over 12 weeks (P = .005), but not Fitbit steps (P = .07). There was a significant improvement in cardiorespiratory fitness (469 ± 108 vs 494 ± 132 m, P = .0034), and 23 participants (42%) improved at least 25 m, signifying a clinically meaningful improvement. Only 4 participants were lost to follow-up over 12 weeks of monitoring. CONCLUSIONS: Patients may need more frequent reminders to be active after an initial counseling session, perhaps getting automated messages based on their step counts syncing to their electronic health record.

RESUMO

PURPOSE OF REVIEW: Treatment of diabetic dyslipidemia is necessary because of its impact on cardiovascular disease, which is the leading cause of death in patients with diabetes. In the past, standard treatment of diabetic dyslipidemia focused only on correcting lipids. Although this remains the mainstay of treatment, because new antihyperglycemic treatments reduce cardiovascular events with minimal effect on dyslipidemia, a new approach is both timely and relevant. RECENT FINDINGS: LDL-lowering remains the focus of treatment for diabetic dyslipidemia, especially in patients with both diabetes and cardiovascular disease (CVD). Higher intensity statin therapy or lower LDL cholesterol goals are recommended in these patients. Combination therapy, especially with ezetimibe, fibrates, bile acid sequestrants, PCSK9 inhibitors and omega 3 fatty acids should be considered along with selected new agents to reduce glycemia. SUMMARY: As diabetic dyslipidemia plays a key role in CVD, aggressive treatment is indicated. New research targets include apo-CIII and lipoprotein(a) [Lp(a)]. In addition, new antihyperglycemic therapy is changing diabetes care and altering treatment guidelines. The most recent American Diabetes Association Standards of Care has expanded its recommendations for people with CVD and diabetes, suggesting that medications validated to improve cardiac health should be strongly considered.

RESUMO

BACKGROUND: Patients undergoing cardiovascular (CV) procedures often have suboptimal CV risk factor control and may benefit from strategies targeting healthy lifestyle behaviors and education. Implementation of prevention strategies may be particularly effective at this point of heightened motivation. METHODS: A prospective, randomized, pilot study was conducted in 400 patients undergoing a nonurgent CV procedure (cardiac catheterization ± revascularization) to evaluate the impact of different prevention strategies. Patients were randomized in a 1:1:1 fashion to usual care (UC; group A, n = 134), in-hospital CV prevention consult (PC; group B, n = 130), or PC plus behavioral intervention program (telephone-based motivational interviewing and optional tailored text messages) (group C, n = 133). The primary end point was the Δ change in non-high-density lipoprotein cholesterol (non-HDL-C) from baseline to 6 month. RESULTS: The mean age was 64.6 ± 10.8 years, 23.7% were female, and 31.5% were nonwhite. After 6 months, the absolute difference in non-HDL-C for all participants was -19.8 mg/dL (95% CI -24.1 to -15.6, P < .001). There were no between-group differences in the primary end point for the combined PC groups (B and C) versus UC, with a Δ adjusted between group difference of -5.5 mg/dL (95% CI -13.1 to 2.1, P = .16). Patients in the PC groups were more likely to be on high-intensity statins at 6 months (52.9% vs 38.1%, P = .01). After excluding participants with baseline non-HDL-C <100 mg/dL (initial exclusion criterion), Δ non-HDL-C and Δ low-density lipoprotein cholesterol were improved in the PC groups compared to UC (non-HDL-C -8.13 mg/dL [-16.00 to -0.27], P = .04; low-density lipoprotein cholesterol -7.87mg/dL [-15.10 to -0.64], P = .03). CONCLUSIONS: Although non-HDL-C reduction at 6 months following a nonurgent CV procedure was not significant in the overall cohort, an increased uptake in high-potency statins may translate into improved long-term health outcomes and cost reductions.

RESUMO

Diabetes mellitus (diabetes) is associated with significantly increased risk of peripheral vascular disease. Diabetes is classified as a coronary heart disease (CHD) risk equivalent, but it is unknown whether diabetes is a CHD risk equivalent for peripheral vascular disease. The objective was to evaluate the odds of peripheral arterial disease (PAD) or carotid artery stenosis (CAS) among participants with diabetes, CHD, or both, compared with participants without diabetes or CHD, in a nationwide vascular screening database. We hypothesized that diabetes and CHD would confer similar odds of PAD and CAS. METHODS: A cross-sectional analysis of all eligible Life Line Screening Inc participants age 30 to 90 years with ankle brachial indices for PAD (ankle brachial index <0.9 in either leg) and carotid artery duplex ultrasonographic imaging for CAS (internal CAS ≥50%) was performed (N=3,522,890). RESULTS: Diabetes and CHD were present in 372,330 (10.7%) and 182,760 (5.8%) of participants, respectively; PAD and CAS were present in 155,000 (4.4%) and 130,347 (3.7%) of participants. After multivariable adjustment, PAD odds were 1.56 (95% CI 1.54-1.59) and 1.69 (95% CI 1.65-1.73) for participants with diabetes or CHD, respectively. Participants with both diabetes and CHD had 2.75-fold increased odds of PAD (95% CI 2.66-2.85). Findings were similar for CAS; compared with no diabetes or CHD, CAS odds increased for participants with diabetes alone (1.53, 95% CI 1.50-1.56), CHD alone (1.72, 95% CI 1.68-1.76), and both diabetes and CHD (2.57, 95% CI 2.49-2.66). Findings were consistent for women and men. CONCLUSION: In a large database of more than 3.5 million self-referred participants, diabetes was a CHD risk equivalent for PAD and CAS, and participants with comorbid diabetes and CHD had an especially robust association with PAD and CAS. Counseling regarding screening and prevention of peripheral vascular disease may be useful for patients with diabetes.

RESUMO

BACKGROUND: Diabetes mellitus (DM) and metabolic syndrome are important targets for secondary prevention in cardiovascular disease. However, the prevalence in patients undergoing elective percutaneous coronary intervention is not well defined. We aimed to analyse the prevalence and characteristics of patients undergoing percutaneous coronary intervention with previously unrecognized prediabetes, diabetes and metabolic syndrome. METHODS: Data were collected from 740 patients undergoing elective percutaneous coronary intervention between November 2010 and March 2013 at a tertiary referral center. Prevalence of DM and prediabetes was evaluated using Haemoglobin A1c (A1c ≥ 6.5% for DM, A1c 5.7-6.4% for prediabetes). A modified definition was used for metabolic syndrome [three or more of the following criteria: body mass index ≥30 kg/m2; triglycerides ≥ 150 mg/dL; high density lipoprotein <40 mg/dL in men and <50 mg/dL in women; systolic blood pressure ≥ 130 mmHg and/or diastolic ≥ 85 mmHg; and A1c ≥ 5.7% or on therapy]. RESULTS: Mean age was 67 years, median body mass index was 28.2 kg/m(2) and 39% had known DM. Of those without known DM, 8.3% and 58.5% met A1c criteria for DM and for prediabetes at time of percutaneous coronary intervention. Overall, 54.9% met criteria for metabolic syndrome (69.2% of patients with DM and 45.8% of patients without DM). CONCLUSION: Among patients undergoing elective percutaneous coronary intervention, a substantial number were identified with a new DM, prediabetes, and/or metabolic syndrome. Routine screening for an abnormal glucometabolic state at the time of revascularization may be useful for identifying patients who may benefit from additional targeting of modifiable risk factors.

RESUMO

Testosterone therapy is recommended for men with symptomatic androgen deficiency and unequivocally low testosterone levels. Although the prevalence of hypogonadism seems relatively constant, studies of prescribing patterns in both the United States and the United Kingdom show a dramatic increase in testosterone prescription in recent years, possibly due to increased marketing and inappropriate therapy. Concurrent with this, there has been growing concern regarding the potential adverse effects of testosterone therapy, particularly its cardiovascular risks. In this review, we present our current understanding of the implications of testosterone deficiency, as well as the conflicting evidence surrounding the cardiovascular effects of testosterone replacement therapy. Although there is a lack of adequate data, based on the current evidence, we conclude that testosterone therapy can be safely considered in men with appropriately diagnosed clinical androgen deficiency and increased cardiovascular risk after a thorough discussion of potential risks and with guideline recommended safety monitoring.

RESUMO

BACKGROUND: The American Heart Association recommends targeting 7 cardiovascular (CV) health metrics to reduce morbidity and mortality. Control of these targets in patients undergoing CV intervention is uncertain. METHODS: We prospectively studied patients undergoing elective percutaneous coronary or peripheral intervention from November 2010 to May 2012. We recorded data on patient demographics, clinical characteristics, and social history. Risk factor control was categorized as ideal, intermediate, or poor according to the 7 American Heart Association-defined CV health metrics (smoking status, body mass index, physical activity, diet, cholesterol, blood pressure, and metabolic control). Linear regression model was used to evaluate the association between baseline characteristics and poor CV health. RESULTS: Among 830 consecutive patients enrolled, mean age is 67.3 ± 10.8 years, 74.2% are male, and 62.1% are white. The adequacy of achievement of ideal CV health is suboptimal in our cohort; the mean number of ideal CV metrics is 2.15 ± 1.06. Less than 1 in 10 (9.7%) met ≥4 ideal CV health metrics. After multivariate analysis, male sex (P = .04), nonwhite race (P = .01), prior coronary artery disease (P < .01), prior peripheral arterial disease (P < .01), and history of depression (P = .01) were significantly associated with poor CV health. CONCLUSIONS: Among patients referred for elective CV intervention, achievement of ideal CV health is poor. Elective interventions represent an opportunity to identify and target CV health for risk factor control and secondary prevention.

RESUMO

The ability for statins to reduce major cardiovascular events and mortality has lead to this drug class being the most commonly prescribed in the world. In particular, the benefit of these drugs in type 2 diabetes (T2D) is well established. In February 2012, the Food and Drug Administration released changes to statin safety label to include that statins have been associated with increases in hemoglobin A1C and fasting serum glucose levels. This has stirred much debate in the medical community. Estimate for new onset diabetes from statin treatment is approximately one in 255 patients over four years. The number needed to treat for statin benefit is estimated at one in 40 depending on the population. The mechanism of this link remains unknown. Statins may accelerate progression to diabetes via molecular mechanisms that impact insulin resistance and cellular metabolism of carbohydrates. It remains clear that the benefit of statin therapy outweighs the risk of developing diabetes.

RESUMO

Almost one third of annual worldwide mortality is attributed to cardiovascular disease (CVD), making it the leading cause of global death. Dyslipidemia is a well-established risk factor for CVD and plays a pivotal role in the pathogenesis of atherosclerosis. Statins, which inhibit 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase and lower low-density lipoprotein cholesterol, have emerged as the most effective therapy to date against atherothrombotic CVD. Although their role in secondary prevention of CVD is undisputed, it remains a topic for debate as to how widely they should be used for primary prevention. The Framingham Risk Score and the National Cholesterol Education Program Adult Treatment Panel III guidelines are the cornerstones for the current guidelines for primary prevention statin therapy. Although these guidelines serve as help to evaluate cardiovascular risk and effectively identify many patients who will benefit from statin therapy, there is a growing population of "intermediate-risk" patients who may be undertreated. Additional noninvasive tests may complement the traditional risk scores, potentially expanding the indications for statins.

RESUMO

OPINION STATEMENT: The pathogenesis of cardiovascular disease is a complex and dynamic process. The renin-angiotensin-aldosterone system (RAAS) is a potent and powerful mediator in the homeostasis of the cardiovascular and renal systems. RAAS blockade via angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) has been consistently proven to be an effective and safe strategy for the primary and secondary prevention of cardiovascular disease in patients across a wide spectrum of risk. Although the beneficial effects of RAAS blockade may be due to its effects on central and peripheral blood pressure, there are many additional mechanisms to consider that may contribute additional protection. While a combination of ACE inhibitors and ARBs has not yielded significantly positive results, the newer class of direct renin inhibitors (DRIs) may offer a novel and effective strategy for monotherapy as well as in combination.

RESUMO

INTRODUCTION: Sodium-glucose cotransporter-2 [SGLT2] inhibitors reduce cardiovascular events and mortality in patients with diabetes, particularly patients with established cardiovascular disease. Euglycemic diabetic ketoacidosis [euDKA], a complication of SGLT2 therapy, can be exacerbated by a low carbohydrate diet. CASE REPORT: A 61-year-old man with a history of type 2 diabetes, taking an SGLT2 inhibitor empagliflozin 10 mg orally daily, presented to the emergency room with a 2-day history of nausea and chest pain. A week prior to presentation, he had started a ketogenic diet. He was initially admitted with a diagnosis of acute coronary syndrome. On initial assessment in the emergency room, his cardiac enzymes were normal and there were no ischemic changes in his ECG. As there was concern for unstable angina, he underwent cardiac catheterization, which showed a known total occlusion with collaterals and arteries with a non-obstructive disease without any evidence of acute plaque rupture. His baseline laboratory assessments revealed an elevated anion gap of 17, increased urinary and plasma ketones, and metabolic acidosis. His plasma glucose level was 84 mg/dL. The diagnosis of euDKA was made, and treatment with intravenous fluids and insulin was initiated. His chest pain and nausea subsequently resolved. CONCLUSION: We present a case of euDKA triggered by a ketogenic diet while on SGLT2 inhibitor therapy presenting as chest pain. The recognition of euDKA is important in the context of increased SGLT2 use for the management of cardiovascular risk for patients with diabetes.

RESUMO

Given the intersection between diabetes mellitus and cardiovascular disease (CVD), pharmacologic agents used to treat type 2 diabetes mellitus must show cardiovascular safety. Comorbid conditions, including heart failure and chronic kidney disease, are increasingly prevalent in patients with diabetes; therefore, they also play a large role in drug safety. Although biguanides, sulfonylurea, glitazones, and dipeptidyl peptidase 4 inhibitors have variable effects on cardiovascular events, sodium glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists have consistently shown safety and reduction in cardiovascular events in patients with established CVD. These medications are becoming essential tools for cardioprotection for patients with diabetes and CVD. They may also have roles in primary prevention and renal protection. This paper will review the cardiovascular impact, adverse effects, and possible mechanisms of action of pharmacologic agents used to treat patients with type 2 diabetes.

RESUMO

Morbidity and mortality associated with cardiovascular disease can be significantly modified through lifestyle interventions, yet there is little emphasis on nutrition and lifestyle in medical education. Improving nutrition education for future physicians would likely lead to improved preparedness to counsel patients on lifestyle interventions. An online anonymous survey of medical residents, cardiology fellows, and faculty in Internal Medicine and Cardiology was conducted at New York University Langone Health assessing basic nutritional knowledge, self-reported attitudes and practices. A total of 248 physicians responded (26.7% response rate). Nutrition knowledge was fair, but few (13.5%) felt adequately trained to discuss nutrition with patients. A majority (78.4%) agreed that additional training in nutrition would allow them to provide better clinical care. Based on survey responses, a dedicated continuing medical education (CME) conference was developed to improve knowledge and lifestyle counseling skills of healthcare providers. In postconference evaluations, attendees reported improved knowledge of evidence-based lifestyle interventions. Most noted that they would prescribe a Mediterranean or plant-based diet and would make changes to their practice based on the conference. An annual CME conference on diet and lifestyle can effectively help interested providers overcome barriers to lifestyle change in clinical practice through improved nutrition knowledge.

RESUMO

OBJECTIVES: We evaluated the effect of metabolic syndrome (a risk factor for the development of coronary artery disease) on survival in patients with established coronary artery disease. METHODS: Survival was determined for 2886 patients with coronary artery disease diagnosed by cardiac catheterization performed between 1990 and 2005 at a Department of Veterans Affairs hospital. Variables obtained from the computerized medical record were evaluated in multivariate analysis by Cox regression. The analysis was performed for the entire population; separate analyses were performed for patient cohorts treated with percutaneous coronary intervention and medication (n=1274), coronary artery bypass grafting and medication (n=1096), or medication alone (n=516). RESULTS: Although age (odds ratio 0.948; P<0.000), left ventricular function (odds ratio 0.701; P<0.000), serum creatinine (odds ratio 0.841; P<0.000), and smoking (odds ratio 0.873; P=0.019) were all strong predictors of mortality. Metabolic syndrome had no independent effect irrespective of diabetic status. CONCLUSION: Metabolic syndrome does not impact survival patients with coronary artery disease treated by revascularization and/or medical therapy.

RESUMO

This article is designed for the general cardiologist, endocrinologist, and internist caring for patients with diabetes and coronary artery disease. Despite the burden of coronary disease in diabetics, little is known about the impact of commonly used oral hypoglycemic agents on cardiovascular outcomes. As the untoward effects of insulin resistance (IR) are increasingly recognized, there is interest in targeting this defect. Insulin resistance contributes to dyslipidemia, hypertension, inflammation, hypercoagulability, and endothelial dysfunction. The aggregate impact of this process is progression of systemic atherosclerosis and an increased risk of adverse cardiovascular outcomes. As such, much attention has been paid to the peroxisome-proliferator-activated receptor gamma (PPARg) agonists rosiglitazone and pioglitazone (thiazolidinediones [TZDs]). Many studies have demonstrated a beneficial effect on the atherosclerotic process; specifically, these agents have been shown to reduce markers of inflammation, retard progression of carotid intimal thickness, prevent restenosis after coronary stenting, and prevent cardiovascular death and myocardial infarction in 1 large trial. Such benefits come at the risk of fluid retention and heart failure (HF) exacerbation, and the net effect on plasma lipids is still poorly understood. Thus, the aggregate risk-benefit ratio is poorly defined. A recent meta-analysis has raised significant concerns regarding the overall cardiovascular safety of 1 particular PPARg agonist (rosiglitazone), prompting international debate and regulatory changes. This review scrutinizes the clinical evidence regarding the cardiovascular risks and benefits of PPARg agonists. Future studies of PPARg agonists, and other emerging drugs that treat IR and diabetes, must be designed to look at cardiovascular outcomes.

RESUMO

Type 2 diabetes mellitus (T2D) is a major risk factor for cardiovascular disease (CVD), the most common cause of death in T2D. Despite improved risk factor control, however, adults with T2D continue to experience substantial excess CVD risk. Until recently, however, improved glycemic control has not been associated with robust macrovascular benefit. The advent of 2 new classes of antihyperglycemic agents, the sodium-glucose cotransporter-2 inhibitors and the glucagon-like peptide-1 receptor agonists, and their respective large cardiovascular outcome trials, has led to a paradigm shift in how cardiologists and heath care practitioners conceptualize T2D treatment. Herein, the authors review the recent trial evidence, the potential mechanisms of action of the sodium-glucose cotransporter-2 inhibitors and the glucagon-like peptide-1 receptor agonists, safety concerns, and their use for the primary prevention of CVD as well as in diabetic patients with impaired renal function and heart failure.

RESUMO

Patients with diabetes mellitus have increased rates of atherosclerotic cardiovascular disease (CVD) and heart failure (HF). This increase occurs despite optimal lipid-lowering therapies. We reviewed clinical trials of diabetes treatments and their effects on circulating plasma lipoproteins and CVD. Several earlier studies failed to demonstrate clear CVD benefit from diabetes therapies. In addition, triglyceride-reducing agents did not reduce overall CVD in large clinical trials although these trials were not conducted in cohorts selected as hypertriglyceridemic. Specific classes such as the thiazolidinediones increased HF. After Food and Drug Administration mandates for more rigorous safety data, recent studies have not only demonstrated CVD safety for many diabetes mellitus agents, but have also shown that certain newer medications such as empagliflozin, canagliflozin, liraglutide, and semaglutide reduce CVD. Moreover, pioglitazone use in insulin-resistant patients has resulted in decreased cerebrovascular and cardiovascular events, suggesting a protective vascular effect of this agent. Benefits from these newer classes of medications are unlikely to be because of improved lipoprotein profiles. These disparities in diabetes medication effects on CVD are likely attributable to each drug or drug class' cardiometabolic effects. Selecting medications based solely on their potential to lower hemoglobin A1C is an outdated therapeutic approach. We propose a new algorithm for treatment of patients with type II diabetes such that medication selection is based on the presence or risk of coronary artery disease and/or HF.

RESUMO

BACKGROUND: Lipoprotein(a) [Lp(a)] is an inherited atherogenic lipoprotein and an independent risk factor for atherosclerotic cardiovascular disease; however, its clinical role remains limited. OBJECTIVE: We hypothesized that Lp(a) screening in high cardiovascular risk patients could provide insight into disease pathogenesis and modify physician behavior for treatment intensification targeting traditional risk factors when Lp(a)-related risk was identified. METHODS: We screened 113 patients presenting electively for percutaneous coronary intervention (PCI) for Lp(a) who met any of the following criteria: (1) premature coronary artery disease (male age <55 years, female age <65 years); (2) family history of premature coronary artery disease; (3) progression to PCI despite well-controlled traditional risk factors (blood pressure <140/90 mm Hg, and low-density lipoprotein cholesterol <100 mg/dL, and HbA1c <7%, and nonsmoker); or (4) progression to PCI despite at least moderate intensity statin use (simvastatin 40, atorvastatin 40-80, or rosuvastatin 20-40 mg daily). RESULTS: In this high-risk cohort, Lp(a) was elevated in nearly half of all subjects, including those with seemingly well-controlled lipids by prior guidelines, suggesting a role for Lp(a) in conferring residual cardiovascular risk. In our cohort, when screened positive, knowledge of an elevated Lp(a) did not influence referring physicians' treatment intensification targeting traditional modifiable cardiovascular risk factors (P = .18). CONCLUSION: When screened judiciously, elevated levels of Lp(a) are highly prevalent in high cardiovascular risk patients, including at a young age, presenting for PCI and may contribute to previously unappreciated residual cardiovascular risk.

RESUMO

Type 2 diabetes mellitus (T2D) is a major risk factor for cardiovascular disease (CVD), the most common cause of death in T2D. Yet, <50% of U.S. adults with T2D meet recommended guidelines for CVD prevention. The burden of T2D is increasing: by 2050, approximately 1 in 3 U.S. individuals may have T2D, and patients with T2D will comprise an increasingly large proportion of the CVD population. The authors believe it is imperative that we expand the use of therapies proven to reduce CVD risk in patients with T2D. The authors summarize evidence and guidelines for lifestyle (exercise, nutrition, and weight management) and CVD risk factor (blood pressure, cholesterol and blood lipids, glycemic control, and the use of aspirin) management for the prevention of CVD among patients with T2D. The authors believe appropriate lifestyle and CVD risk factor management has the potential to significantly reduce the burden of CVD among patients with T2D.
