RESUMEN

BACKGROUND: Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) lower atherosclerotic cardiovascular disease (ASCVD) event risk. OBJECTIVE: Analyze patient characteristics associated with time to PCSK9i initiation following an acute myocardial infarction (AMI). METHODS: We analyzed characteristics of patients ≥21 years of age in the Marketscan or Medicare databases who initiated a PCSK9i 0-89 days, 90-179 days, or 180-365 days after an AMI between July 2015 and December 2018 (n=1,705). We estimated the cumulative incidence of recurrent ASCVD events before PCSK9i initiation. RESULTS: Overall, 42%, 25%, and 33% of patients who initiated a PCSK9i did so 0-89 days, 90-179 days, and 180-365 days following AMI hospital discharge, respectively. Taking ezetimibe prior to AMI hospitalization and initiating ezetimibe within 30 days after AMI hospital discharge were each associated with a higher likelihood of PCSK9i initiation in the 0-89 days versus 180-365 days post-discharge (adjusted odds ratio [OR] 1.83, 95% confidence interval [95%CI] 1.35-2.49 and 1.76, 95%CI 1.11-2.80, respectively). Statin use before and statin initiation within 30 days after AMI hospitalization were associated with a lower likelihood of PCSK9i initiation 0-89 days versus 180-365 days post-discharge (adjusted OR 0.64, 95%CI 0.49-0.84 and 0.39, 95%CI 0.28-0.54, respectively). Overall, 8.0%, 10.5%, and 12.5% of patients had an ASCVD event at 90, 180, and 365 days following AMI hospital discharge and before initiating a PCSK9i, respectively. CONCLUSION: Among patients initiating a PCSK9i after AMI, a low proportion did so within 89 days of hospital discharge. Many patients had a recurrent ASCVD event before treatment initiation.

RESUMEN

In the continuum of patients with Alzheimer's disease (AD), mild cognitive impairment (MCI), and normal controls, a possible association of verbal memory and endogenous estradiol (E(2)) levels was investigated. Verbal episodic memory was measured with a german version of the California verbal memory test (CVLT). Results were controlled for apolipoprotein E (ApoE) phenotype. We studied 37 controls, 32 MCIs and 117 ADs. Groups differed in all trials of the CVLT (P < 0.001) and in E(2) levels (P < 0.001). E2 levels differed significantly between groups only among females (P < 0.001). In females correcting for age and ApoE, there was an overall correlation between CVLT delayed recall and level of E(2) (P = 0.025). Stepwise regression analyses found E(2) level to be a significant predictor for CVLT delayed recall (P < 0.001). It may be concluded that lower E(2) levels occur more in the course of the disease than may be considered as a risk factor per se.

RESUMEN

OBJECTIVE: This study investigated the relation between psychotropic medication use and adverse cardiovascular (CV) events in women with symptoms of myocardial ischaemia undergoing coronary angiography. METHOD: Women enrolled in the Women's Ischemia Syndrome Evaluation (WISE) were classified into one of four groups according to their reported antidepressant and anxiolytic medication usage at study intake: (1) no medication (n = 352); (2) anxiolytics only (n = 67); (3) antidepressants only (n = 58); and (4) combined antidepressant and anxiolytics (n = 39). Participants were followed prospectively for the development of adverse CV events (for example, hospitalisations for non-fatal myocardial infarction, stroke, congestive heart failure and unstable angina) or all-cause mortality over a median of 5.9 years. RESULTS: Use of antidepressant medication was associated with subsequent CV events (HR 2.16, 95% CI 1.21 to 3.93) and death (HR 2.15, 95% CI 1.16 to 3.98) but baseline anxiolytic use alone did not predict subsequent CV events and death. In a final regression model that included demographics, depression and anxiety symptoms, and risk factors for cardiovascular disease, women in the combined medication group (that is, antidepressants and anxiolytics) had higher risk for CV events (HR 3.98, CI 1.74 to 9.10, p = 0.001 and all-cause mortality (HR 4.70, CI 1.7 to 2.97, p = 0.003) compared to those using neither medication. Kaplan-Meier survival curves indicated that there was a significant difference in mortality among the four medication groups (p = 0.001). CONCLUSIONS: These data suggest that factors related to psychotropic medication such as depression refractory to treatment, or medication use itself, are associated with adverse CV events in women with suspected myocardial ischaemia.

RESUMEN

OBJECTIVE: To examine by secondary analysis of the Treating to New Targets (TNT) study whether the benefits of intensive versus standard levels of lipid lowering are equally applicable to women. METHODS: A total of 10 001 patients (1902 women) with stable coronary heart disease (CHD) were randomised to double-blind treatment with atorvastatin 10 or 80 mg/day for a median follow-up of 4.9 years. RESULTS: In women and men, intensive treatment with atorvastatin 80 mg significantly reduced the rate of major cardiovascular events compared with atorvastatin 10 mg. Among women, the relative and absolute reductions were 27% and 2.7%, respectively (hazard ratio (HR) = 0.73, 95% confidence interval (CI) 0.54 to 1.00, p = 0.049). In men, the corresponding rate reductions were 21% and 2.2% (HR = 0.79, 95% CI 0.69 to 0.91, p = 0.001). The number needed to treat value (to prevent one cardiovascular event over 4.9 years compared with patients treated with atorvastatin 10 mg) for atorvastatin 80 mg was 29 for women and 30 for men. Rates of death of non-cardiovascular origin in the atorvastatin 80 mg and atorvastatin 10 mg were 3.6% and 1.6%, respectively (p = 0.004) among women, and 2.8% and 3.1% (p = 0.47) among men. CONCLUSION: Intensive lipid-lowering treatment with atorvastatin 80 mg produced significant reductions in relative risk for major cardiovascular events compared with atorvastatin 10 mg in both women and men with stable CHD.

RESUMEN

AIMS: We sought to determine whether fasting or post-challenge glucose were associated with progression of coronary atherosclerosis in non-diabetic women. METHODS: We performed a post-hoc analysis of 132 non-diabetic women who underwent 75-g oral glucose tolerance testing. The primary outcome of interest was progression of atherosclerosis determined by baseline and follow-up coronary angiography, a mean of 3.1 +/- 0.9 years apart. We analysed the association of change in minimal vessel diameter (DeltaMD) by quartile of fasting and post-challenge glucose using mixed models that included adjustment for age, systolic blood pressure, total : high-density lipoprotein cholesterol ratio, current smoking, lipid-lowering and anti-hypertensive medication use and other covariates. RESULTS: At baseline, participants had a mean age of 65.7 +/- 6.7 years and a mean body mass index of 27.9 +/- 8.5 kg/m(2). Although there were no significant differences in atherosclerotic progression by fasting glucose category (P for trend across quartiles = 0.99), there was a significant inverse association between post-challenge glucose and DeltaMD (in mm) (Q1 : 0.01 +/- 0.03; Q2 : 0.08 +/- 0.03; Q3 : 0.13 +/- 0.03; Q4 : 0.11 +/- 0.03; P for trend = 0.02). CONCLUSIONS: In post-menopausal women without diabetes, post-challenge glucose predicts angiographic disease progression. These findings suggest that even modest post-challenge hyperglycaemia influences the pathogenesis of atherosclerotic progression.

RESUMEN

We have electronically wired the cytochrome P450 BM3 heme domain to a graphite electrode with the use of a pyrene-terminated tether. AFM images clearly reveal that pyrene-wired enzyme molecules are adsorbed to the electrode surface. The enzyme-electrode system undergoes rapid and reversible electron transfer, displaying a standard rate constant higher than that of any other P450-electrode system. We also show that the graphite-pyrene-BM3 system catalyzes the four-electron reduction of dioxygen to water.

RESUMEN

BACKGROUND: Although severe chronic kidney disease (CKD) is an independent predictor of mortality among patients with coronary artery disease, the impact of mild CKD on morbidity and mortality has not been fully defined. METHODS AND RESULTS: Morbidity and mortality for the 3608 patients with multivessel coronary artery disease enrolled in the Bypass Angioplasty Revascularization Investigation randomized trial and registry were compared on the basis of the presence and absence of CKD, defined as a preprocedure serum creatinine level of >1.5 mg/dL. Seventy-six patients had CKD. Patients with renal insufficiency were older and more likely to have a history of diabetes, hypertension, and other comorbidities. Among patients undergoing PTCA, patients with CKD had a greater frequency of in-hospital death and cardiogenic shock (P<0.05 and 0.01, respectively). There was a trend toward a larger proportion of patients with CKD experiencing angina at 5 years (P=0.079). Patients with CKD had more cardiac admissions (P=0.003 and <0.0001 for patients undergoing PTCA and CABG, respectively) and a shorter time to subsequent CABG after initial revascularization than patients without CKD (P=0.01). CKD was associated with a higher risk of death at 7 years, both of all causes (relative risk 2.2, P<0.001) and of cardiac causes (relative risk 2.8, P<0.001). CONCLUSIONS: CKD is associated with an increased risk of recurrent hospitalization, subsequent CABG, and mortality. This increased risk of death is independent of and additive to the risk associated with diabetes.

RESUMEN

Cardiovascular disease is the primary cause of death among women in the United States, in part due to a very high prevalence of dyslipidemia. Clinical trials have shown that low-density lipoprotein cholesterol-lowering therapy can decrease angiographic progression of coronary disease and decrease clinical events among women and men. Although hormone replacement therapy has beneficial effects on the lipoprotein profile, its role in cardiovascular disease prevention remains unclear. The recently released Third Report of the National Cholesterol Education Program Expert Panel provides detailed guidelines for the management of dyslipidemia in women, with a focus on low-density lipoprotein cholesterol and intensity guided by risk of cardiovascular events.

RESUMEN

OBJECTIVE: Clinical cardiovascular disease (CVD) is highly prevalent among people with diabetes. However, there is little information regarding the prevalence of subclinical CVD and its relation to clinical CVD in diabetes and in the glucose disorders that precede diabetes. RESEARCH DESIGN AND METHODS: Participants in the Cardiovascular Health Study, aged > or = 65 years (n = 5,888), underwent vascular and metabolic testing. Individuals with known disease in the coronary, cerebral, or peripheral circulations were considered to have clinical disease. Those without any clinical disease in whom CVD was detected by ultrasonography, electrocardiography, or ankle arm index in any of the three vascular beds were considered to have isolated subclinical disease. RESULTS: Approximately 30% of the cohort had clinical disease, and approximately 60% of the remainder had isolated subclinical disease. In those with normal glucose status, isolated subclinical disease made up most of the total CVD. With increasing glucose severity, the proportion of total CVD that was clinical disease increased; 75% of men and 66% of women with normal fasting glucose status had either clinical or subclinical CVD. Among those with known diabetes, the prevalence was approximately 88% (odds ratio [OR] 2.46 for men and 4.22 for women, P < 0.0001). There were intermediate prevalences and ORs for those with impaired fasting glucose status and newly diagnosed diabetes. CONCLUSIONS: Isolated subclinical CVD is common among older adults. Glucose disorders are associated with an increased prevalence of total CVD and an increased proportion of clinical disease relative to subclinical disease.

RESUMEN

OBJECTIVES: We undertook an analysis of weight cycling, coronary risk factors and angiographic coronary artery disease (CAD) in women. BACKGROUND: The effect of weight cycling on cardiovascular mortality and morbidity is controversial, and the impact of weight cycling on cardiovascular risk factors is unclear. METHODS: This is a cross-sectional population study of 485 women with coronary risk factors undergoing coronary angiography for evaluation of suspected myocardial ischemia enrolled in the Women's Ischemia Syndrome Evaluation (WISE). Reported lifetime weight cycling-defined as voluntary weight loss of at least 10 lbs at least 3 times--coronary risk factors including core laboratory determined blood lipoproteins and CAD, as determined by a core angiographic laboratory, are the main outcome measures. RESULTS: Overall, 27% of women reported weight cycling--19% cycled 10 to 19 lbs, 6% cycled 20 to 49 lbs, and 2% cycled 50+ lbs. Reported weight cycling was associated with 7% lower high-density lipoprotein cholesterol (HDL-C) levels in women (p = 0.01). The HDL-C effect was directly related to the amount of weight cycled with women who lost > or = 50 lbs/cycle having HDL-C levels 27% lower than noncyclers (p = 0.0025). This finding was independent of other HDL-C modulators, including estrogen status, physical activity level, alcohol intake, body mass index, diabetes, beta-blocker use, cigarette smoking and race. Weight cycling was not associated with an increased prevalence of CAD in this population. CONCLUSIONS: Weight cycling is associated with lower HDL-C in women of a magnitude that is known to be associated with an increased risk of cardiac events as demonstrated in prior clinical trials.

RESUMEN

Physical activity and functional capacity have not been assessed by questionnaire for criterion validity in women. We wished to evaluate the ability of a physical activity and a functional capacity assessment questionnaire to predict functional capacity measured by treadmill exercise stress testing, as well as correlate with cardiac risk factors and angiographic coronary artery disease (CAD) in women. In a National Heart, Lung and Blood Institute (NHLBI)-sponsored cross-sectional population study involving four academic medical centers, 476 women with cardiac risk factors undergoing coronary angiography for evaluation for suspected myocardial ischemia were enrolled in the Women's Ischemia Syndrome Evaluation (WISE). The main outcome measures were functional capacity measured during symptom-limited exercise treadmill testing, cardiac risk factors, and CAD, using core laboratory-determined measures. Physical activity measured by the Postmenopausal Estrogen and Progesterone Intervention physical activity questionnaire (PEPI-Q) and functional capacity measured by the Duke Activity Status Index (DASI) questionnaire, correlated with functional capacity measured in metabolic equivalents (METS), as estimated during symptom-limited exercise treadmill testing (r = 0.27, p = 0.001 and r = 0.31, p = 0. 0002, respectively). The DASI was a significant independent predictor of functional capacity even after adjustment for cardiac risk factors, and the PEPI-Q was not. The DASI and PEPI-Q scores were inversely associated with higher numbers and levels of cardiac risk factors, as well as angiographic CAD. The DASI questionnaire is a reasonable correlate of functional capacity achieved during symptom-limited treadmill exercise testing in women with suspected myocardial ischemia. Lower functional capacity or physical activity measured by the DASI and PEPI-Q, respectively, is associated with more prevalent cardiac risk factors and angiographic CAD. These findings suggest that the DASI and, to a lesser extent, the PEPI-Q have criterion validity for use in health-related research in women.

RESUMEN

BACKGROUND: Reperfusion therapy for acute myocardial infarction (AMI) is a time-dependent intervention that can reduce infarct-related morbidity and mortality. Out-of-hospital patient delay from symptom onset until emergency department (ED) presentation may reduce the expected benefit of reperfusion therapy. OBJECTIVE: To determine the impact of a community educational intervention to reduce patient delay time on the use of reperfusion therapy for AMI. METHODS: This was a randomized, controlled community-based trial to enhance patient recognition of AMI symptoms and encourage early ED presentation with resultant increased reperfusion therapy rates for AMI. The study took place in 44 hospitals in 20 pair-matched communities in five U.S. geographic regions. Eligible study subjects were non-institutionalized patients without chest injury (aged > or =30 years) who were admitted to participating hospitals and who received a hospital discharge diagnosis of AMI (ICD 410); n = 4,885. For outcome assessment, patients were excluded if they were without survival data (n = 402), enrolled in thrombolytic trials (n = 61), receiving reperfusion therapy >12 hours after ED arrival (n = 628), or missing symptom onset or reperfusion times (n = 781). The applied intervention was an educational program targeting community organizations and the general public, high-risk patients, and health professionals in target communities. The primary outcome was a change in the proportion of AMI patients receiving early reperfusion therapy (i.e., within one hour of ED arrival or within six hours of symptom onset). Trends in reperfusion therapy rates were determined after adjustment for patient demographics, presenting blood pressure, cardiac history, and insurance status. Four-month baseline was compared with the 18-month intervention period. RESULTS: Of 3,013 selected AMI patients, 40% received reperfusion therapy. Eighteen percent received therapy within one hour of ED arrival (46% of treated patients), and 32% within six hours of symptom onset (80% of treated patients). No significant difference in the trends in reperfusion therapy rates was attributable to the intervention, although increases in early reperfusion therapy rates were noted during the first six months of the intervention. A significant association of early reperfusion therapy use with ambulance use was identified. CONCLUSIONS: Community-wide educational efforts to enhance patient response to AMI symptoms may not translate into sustained changes in reperfusion practices. However, an increased odds for early reperfusion therapy use during the initiation of the intervention and the association of early therapy with ambulance use suggest that reperfusion therapy rates can be enhanced.

RESUMEN

BACKGROUND: There are few data on possible age and sex differences in presentation of symptoms for patients with acute coronary disease. OBJECTIVE: To investigate demographic differences in presentation of symptoms at the time of hospital presentation for acute myocardial infarction (AMI) and unstable angina. METHODS: The medical records of patients who presented with chest pain and who also had diagnoses of AMI (n = 889) or unstable angina (n = 893) on discharge from 43 hospitals were reviewed as part of data collection activities of the Rapid Early Action for Coronary Treatment trial based in 10 pair-matched communities throughout the USA. RESULTS: Dyspnea (49%), arm pain (46%), sweating (35%), and nausea (33%) were commonly reported by men and women of all ages in addition to the presenting complaint of chest pain. After we had controlled for various characteristics through regression modeling, older persons with AMI were significantly less likely than were younger persons to complain of arm pain and sweating, and men were significantly less likely to report vomiting than were women. Among persons with unstable angina, arm pain and sweating were reported significantly less often by elderly patients. Nausea and back, neck, and jaw pain were more common complaints of women. CONCLUSIONS: Results of this study suggest that there are differences between symptoms at presentation of men and women, and those in various age groups, hospitalized with acute coronary disease. Clinicians should be aware of these differences when diagnosing and managing patients suspected to have coronary heart disease.

RESUMEN

BACKGROUND: The mechanism by which angiotensin-converting enzyme inhibitors reduce mortality rates and disease progression in patients with heart failure is likely mediated in part through prevention of adverse ventricular remodeling. This study examined the effects of the angiotensin-converting enzyme inhibitor captopril and the angiotensin II type 1 receptor antagonist losartan on ventricular volumes and function in elderly patients with heart failure and reduced left ventricular ejection fraction (< or =40%). METHODS: Patients underwent radionuclide ventriculograms (RVG) at baseline and were randomized to either captopril (n = 16) or losartan (n = 13). After 48 weeks, another RVG was obtained. Therapy was then withdrawn for at least 5 days, and the RVG was repeated while the patient was not receiving the drug. RESULTS: At 48 weeks both captopril and losartan significantly reduced left ventricular (LV) end-diastolic volume index (135 +/- 26 to 128 +/- 23 mL/m(2) for losartan, P <.05 vs baseline; 142 +/- 25 to 131 +/- 20 mL/m(2) for captopril, P <.01; mean (SD). Captopril also reduced LV end-systolic volume index (98 +/- 24 to 89 +/- 21 mL/m(2), P <.01 vs. baseline), whereas a nonsignificant trend was observed for the losartan group (97 +/- 23 to 90 +/- 16 mL/m(2), P = not significant). The between-group differences in the changes in LV volumes were not statistically significant. After drug withdrawal, LV end-diastolic volume index remained significantly lower than baseline in the captopril group (P <.01). CONCLUSIONS: Both captopril and losartan prevent LV dilation, representing adverse ventricular remodeling, previously seen with placebo treatment. Reverse remodeling was observed in the captopril group. On the basis of these results, the relative effects on LV remodeling do not provide a rationale for a survival benefit of losartan over captopril.

RESUMEN

We sought to assess the impact of coronary angiography results on use of lipid-lowering agents among women enrolled in the Women's Ischemia Syndrome Evaluation [WISE] study. WISE is a multicenter study designed to evaluate new diagnostic modalities among women undergoing angiography for suspected coronary artery disease (CAD). History of atherosclerosis, risk factors for CAD, and low-density lipoprotein (LDL) cholesterol are determined at baseline. The percentage of women at LDL cholesterol goal, use of lipid-lowering agents, and eligibility for lipid-lowering therapy were determined based on National Cholesterol Education Program II guidelines at baseline and 6-week follow-up. Among the 212 women for whom angiographic data were available, 84 had known atherosclerosis, 80 had no history of atherosclerosis but > or =2 risk factors (high risk), and 48 had no history of atherosclerosis and <2 risk factors (low risk). At baseline, LDL cholesterol goals were met in 24% women with atherosclerosis, in 56% high-risk women, and in 88% low-risk women. Angiography revealed previously undiagnosed CAD in 70% of the high-risk and in 42% of the low-risk women. After angiography results were available, 6 women started lipid-lowering therapy and 2 stopped. Based on National Cholesterol Education Program II guidelines, 63 additional women would have been eligible for pharmacologic lipid-lowering therapy. Intensification of lipid-lowering therapy was not apparent 6 weeks after coronary angiography in women with newly diagnosed CAD or among women whose diagnosis was confirmed.

RESUMEN

BACKGROUND: The National Cholesterol Education Program (NCEP) has designated high-density lipoprotein cholesterol (HDL-C) > or =60 mg/dL a "negative" coronary heart disease (CHD) risk factor, but a substantial proportion of coronary events occur among women despite high HDL-C levels. METHODS AND RESULTS: The objective of this study was to characterize postmenopausal women with prevalent CHD despite HDL-C > or =60 mg/dL and to identify factors that may attenuate the protective effect of high HDL-C. We analyzed baseline data from a randomized, double-blind study of estrogen/progestin replacement therapy in 2763 postmenopausal women <80 years old with CHD. Demographics, CHD risk factors, medications, anthropometrics, and lipid levels were compared among women with low, normal, and high HDL-C by NCEP criteria with and without stratification by use of lipid-lowering medications. Independent correlates of high HDL-C were determined by logistic regression analysis. HDL-C > or =60 mg/dL was present in 20% of participants. Women with high HDL-C were older, better educated, had fewer CHD risk factors, lower triglyceride levels and total cholesterol/HDL-C ratio, and were more likely to report past estrogen and current calcium antagonist, niacin, and statin use. beta-Blocker, diuretic, and fibrate use was less common. Older age, alcohol consumption, niacin, and calcium antagonist use and prior estrogen use were independently associated with high HDL-C, whereas waist-to-hip ratio, smoking, triglyceride level, and beta-blocker and fibrate use were inversely associated (all P <.05). CONCLUSIONS: High HDL-C, as defined by the NCEP, occurred in 20% of women with CHD in this cohort without a concomitantly higher prevalence of other CHD risk factors. Redefinition of "high" HDL-C levels for women may be warranted.

RESUMEN

PURPOSE: Advance directives have been available in parts of the United States for more than 20 years, but research shows that only a small percentage of adults (5-25%) have some form of written advance directive. The purose of this study was to examine the presence of advance directives among persons entering cardiac and pulmonary rehabilitation, and identify characteristics of persons most likely to have advance directives. METHODS: The sample consisted of 336 cardiac patients and 181 pulmonary patients who enrolled in the University of Alabama at Birmingham's Cardiopulmonary Rehabilitation Program between January 1996 and December 1999. As part of the initial program assessment, patients were asked two questions: (1) Do you have a living will? (2) Do you have any advance directives? For the purposes of this study, the two questions were combined to examine the presence of either a living will or other type of advance directive. RESULTS: Results indicate that 25% of both subgroups (cardiac and pulmonary patients) report having written advance directives. Logistic regression analysis indicates that among cardiac patients whites and older persons were more likely to have advance directives. Among pulmonary patients, females and whites were more likely to have advance directives. CONCLUSIONS: These results indicate that only a minority of cardiopulmonary rehabilitation patients have advance directives upon entry into the program, and that the prevalence differs among gender, racial, and age groups. Cardiac and pulmonary rehabilitation programs may be valuable sites for educating patients about advance directives and efforts by rehabilitation personnel may increase the prevalence of advance directives among patients.
