Heart Centers for Women: Historical Perspective on Formation and Future Strategies to Reduce Cardiovascular Disease.

Heart Centers for Women (HCW) developed as a response to the need for improved outcomes for women with cardiovascular disease (CVD). From 1984 until 2012, more women died of CVD every single year in comparison with men. Initially, there was limited awareness and sex-specific research regarding mortality or outcomes in women. HCW played an active role in addressing these disparities, provided focused care for women, and contributed to improvements in these gaps. In 2014 and 2015, death from CVD in women had declined below the level of death from CVD in comparison with men. Even though awareness of CVD in women has increased among the public and healthcare providers and both sex- and gender-specific research is currently required in all research trials, not all women have benefitted equally in mortality reduction. New strategies for HCW need to be developed to address these disparities and expand the current HCW model. The HCW care team needs to direct academic curricula on sex- and gender-specific research and care; expand to include other healthcare professionals and other subspecialties; provide new care models; address diversity; and include more male providers.

LDL cholesterol levels after switch from atorvastatin to rosuvastatin.

OBJECTIVE: Initial statin therapy may not always adequately reduce elevated low-density lipoprotein cholesterol (LDL-C) levels. Although alternative therapies are available, switching to another statin may be beneficial, especially for those at highest risk of cardiovascular disease and events. This study examined changes in LDL-C levels following a switch from 40/80 mg of atorvastatin (ATV) to 20/40 mg of rosuvastatin (RSV). METHODS: This retrospective cohort study used data from the MarketScan administrative claims databases linked to laboratory values. Patients with or at risk for atherosclerotic cardiovascular disease (ASCVD) who switched from ATV 40/80 mg to RSV 20/40 mg and had LDL-C values measured within 90 days before and 30-180 days after the switch were included. The change in LDL-C was quantified for each patient and summarized across all patients and within each switch pattern (e.g. ATV40 to RSV20). RESULTS: There was a significant mean (SD) decrease in LDL-C of 21% (30%) across the whole sample (N = 136) after switching from ATV to RSV. The greatest decrease occurred in patients who switched from ATV40 to RSV40 (N = 20; -29% [19%]; p < .001). Similar changes were observed overall and within each switch pattern when the analysis was limited to patients who were persistent on RSV in the post-switch period (N = 112; -24% [24%]; p < .001). CONCLUSIONS: Switching from ATV to RSV was associated with a significant decrease in LDL-C among high-risk patients. Switching between these two high-intensity statins may offer a viable alternative to other treatment modifications aimed at lowering LDL-C in this population.

Prevention and treatment of atherosclerosis: a practitioner's guide for 2008.

Atherosclerosis causes nearly 75% of cardiovascular-related deaths and is found in 80% to 90% of adults >/=30 years old in the United States. Successful treatment minimizes lifetime chances of cardiovascular events, morbidity, and mortality. Risk factors for atherosclerosis should be monitored, beginning in childhood, even in asymptomatic patients. Modifiable factors (e.g., blood pressure, smoking, serum lipids) and nonmodifiable factors (e.g., age, family history) are important in the overall assessment. Clinicians and patients can partner to produce an individualized treatment plan by choosing from a variety of standard approaches. In some patients, improved dietary choices, increased exercise, and smoking cessation will reduce risk to an acceptable degree. To lower risk further, lipid-lowering pharmacotherapy and antihypertensive medication may be combined with these lifestyle improvements. For most of these patients, reducing low-density lipoprotein cholesterol is the most important lipid-lowering goal, and it is best achieved with a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin). Some patients may benefit from adjunctive therapies that have proven effects (e.g., niacin, fibrates, plant stanols/sterols, omega-3 fatty acids). Antihypertensive regimens may involve stepwise adjustments of multiple medications. Good clinical judgment and communication of expectations and goals are critical for effective management of atherosclerosis.

Outcomes of using high- or low-dose atorvastatin in patients 65 years of age or older with stable coronary heart disease.

BACKGROUND: Increased life expectancy is associated with an increase in the burden of chronic cardiovascular disease. OBJECTIVE: To assess the efficacy and safety of high-dose atorvastatin in patients 65 years of age or older. DESIGN: A prespecified secondary analysis of the Treating to New Targets study, a randomized, double-blind clinical trial. SETTING: 256 sites in 14 countries participating in the Treating to New Targets study. PARTICIPANTS: 10,001 patients (3809 patients > or =65 years of age) with coronary heart disease (CHD) and low-density lipoprotein cholesterol levels less than 3.4 mmol/L (<130 mg/dL). INTERVENTION: Patients were randomly assigned to receive atorvastatin, 10 or 80 mg/d. MEASUREMENTS: The primary end point was the occurrence of a first major cardiovascular event (death from CHD, nonfatal non-procedure-related myocardial infarction, resuscitated cardiac arrest, or fatal or nonfatal stroke). RESULTS: In patients 65 years of age or older, absolute risk was reduced by 2.3% and relative risk by 19% for major cardiovascular events in favor of the high-dose atorvastatin group (hazard ratio, 0.81 [95% CI, 0.67 to 0.98]; P = 0.032). Among the components of the composite outcome, the mortality rates from CHD, nonfatal non-procedure-related myocardial infarction, and fatal or nonfatal stroke (ischemic, embolic, hemorrhagic, or unknown origin) were all lower in older patients who received high-dose atorvastatin, although the difference was not statistically significant for each individual component. The improved clinical outcome in patients 65 years of age or older was not associated with persistent elevations in creatine kinase levels. LIMITATION: Because the study was a secondary analysis, the findings should be interpreted within the context of the main study results. CONCLUSIONS: The analysis suggests that additional clinical benefit can be achieved by treating older patients with CHD more aggressively to reduce low-density lipoprotein cholesterol levels to less than 2.6 mmol/L (<100 mg/dL). The findings support the use of intensive low-density lipoprotein cholesterol-lowering therapy in high-risk older persons with established cardiovascular disease.

Effect of high-dose atorvastatin on hospitalizations for heart failure: subgroup analysis of the Treating to New Targets (TNT) study.

BACKGROUND: Statins reduce the rate of major cardiovascular events in high-risk patients, but their potential benefit as treatment for heart failure (HF) is less clear. METHODS AND RESULTS: Patients (n=10,001) with stable coronary disease were randomized to treatment with atorvastatin 80 or 10 mg/d and followed up for a median of 4.9 years. A history of HF was present in 7.8% of patients. A known ejection fraction <30% and advanced HF were exclusion criteria for the study. A predefined secondary end point of the study was hospitalization for HF. The incidence of hospitalization for HF was 2.4% in the 80-mg arm and 3.3% in the 10-mg arm (hazard ratio, 0.74; 95% confidence interval, 0.59 to 0.94; P=0.0116). The treatment effect of the higher dose was more marked in patients with a history of HF: 17.3% versus 10.6% in the 10- and 80-mg arms, respectively (hazard ratio, 0.59; 95% confidence interval, 0.4 to 0.88; P=0.009). Among patients without a history of HF, the rates of hospitalization for HF were much lower: 1.8% in the 80-mg group and 2.0% in the 10-mg group (hazard ratio, 0.87; 95% confidence interval, 0.64 to 1.16; P=0.34). Only one third of patients hospitalized for HF had evidence of preceding angina or myocardial infarction during the study period. Blood pressure was almost identical during follow-up in the treatment groups. CONCLUSIONS: Compared with a lower dose, intensive treatment with atorvastatin in patients with stable coronary disease significantly reduces hospitalizations for HF. In a post hoc analysis, this benefit was observed only in patients with a history of HF. The mechanism accounting for this benefit is unlikely to be due primarily to a reduction in interim coronary events or differences in blood pressure.
