    A clinician's guide to the ABCs of cardiovascular disease prevention: the Johns Hopkins Ciccarone Center for the Prevention of Heart Disease and American College of Cardiology Cardiosource Approach to the Million Hearts Initiative.
    (Clinical cardiology, 2013-07) Hsu, Steven; Ton, Van-Khue; Dominique Ashen, M; Martin, Seth S; Gluckman, Ty J; Kohli, Payal; Sisson, Stephen D; Blumenthal, Roger S; Blaha, Michael J
    Atherosclerotic cardiovascular disease (CVD) is the leading cause of death in the United States and worldwide. Fortunately, it is often preventable with early adoption of lifestyle modification, prevention of risk factor onset, and aggressive treatment of existing risk factors. The Million Hearts Initiative is an effort by the Centers for Disease Control that aims to prevent 1 million myocardial infarctions and strokes over the next 5 years. As part of this initiative, we present a simply organized "ABCDE" approach for guiding a consistent comprehensive approach to managing cardiovascular risk in daily clinical practice. ABCDE stands for assessment of risk, antiplatelet therapy, blood pressure management, cholesterol management, cigarette/tobacco cessation, diet and weight management, diabetes prevention and treatment, and exercise, interventions regularly used to reduce cardiovascular (CV) risk. Throughout this article we summarize recommendations related to each topic and reference landmark trials and data that support our approach. We believe that the ABCDE approach will be the core framework for addressing CV risk in our effort to prevent CVD.

    Association Between Comorbidities and Outcomes in Heart Failure Patients With and Without an Implantable Cardioverter-Defibrillator for Primary Prevention.
    (J Am Heart Assoc, 2015-08-06) Khazanie, Prateeti; Hellkamp, Anne S; Fonarow, Gregg C; Bhatt, Deepak L; Masoudi, Frederick A; Anstrom, Kevin J; Heidenreich, Paul A; Yancy, Clyde W; Curtis, Lesley H; Hernandez, Adrian F; Peterson, Eric D; Al-Khatib, Sana M
    BACKGROUND: Implantable cardioverter-defibrillator (ICD) therapy is associated with improved outcomes in patients with heart failure (HF), but whether this association holds among older patients with multiple comorbid illnesses and worse HF burden remains unclear. METHODS AND RESULTS: Using the National Cardiovascular Data Registry's ICD Registry and the Get With The Guidelines-Heart Failure (GWTG-HF) registry linked with Medicare claims, we examined outcomes associated with primary-prevention ICD versus no ICD among HF patients aged ≥65 years in clinical practice. We included patients with an ejection fraction ≤35% who received (ICD Registry) and who did not receive (GWTG-HF) an ICD. Compared with patients with an ICD, patients in the non-ICD group were older and more likely to be female and white. In matched cohorts, the 3-year adjusted mortality rate was lower in the ICD group versus the non-ICD group (46.7% versus 55.8%; adjusted hazard ratio [HR] 0.76; 95% CI 0.69 to 0.83). There was no associated difference in all-cause readmission (HR 0.99; 95% CI 0.92 to 1.08) but a lower risk of HF readmission (HR 0.88; 95% CI 0.80 to 0.97). When compared with no ICD, ICDs were also associated with better survival in patients with ≤3 comorbidities (HR 0.77; 95% CI 0.69 to 0.87) and >3 comorbidities (HR 0.77; 95% CI 0.64 to 0.93) and in patients with no hospitalization for HF (HR 0.75; 95% CI 0.65 to 0.86) and at least 1 prior HF hospitalization (HR 0.69; 95% CI 0.58 to 0.82). In subgroup analyses, there were no interactions between ICD and mortality risk for comorbidity burden (P=0.95) and for prior HF hospitalization (P=0.46). CONCLUSION: Among older HF patients, ICDs for primary prevention were associated with lower risk of mortality even among those with high comorbid illness burden and prior HF hospitalization.

    Clinician's guide to the updated ABCs of cardiovascular disease prevention.
    (Journal of the American Heart Association, 2014-09) Kohli, Payal; Whelton, Seamus P; Hsu, Steven; Yancy, Clyde W; Stone, Neil J; Chrispin, Jonathan; Gilotra, Nisha A; Houston, Brian; Ashen, M Dominique; Martin, Seth S; Joshi, Parag H; McEvoy, John W; Gluckman, Ty J; Michos, Erin D; Blaha, Michael J; Blumenthal, Roger S
    To facilitate the guideline-based implementation of treatment recommendations in the ambulatory setting and to encourage participation in the multiple preventive health efforts that exist, we have organized several recent guideline updates into a simple ABCDEF approach. We would remind clinicians that evidence-based medicine is meant to inform recommendations but that synthesis of patient-specific data and use of appropriate clinical judgment in each individual situation is ultimately preferred.

    Meta-analysis of Placebo-Controlled Randomized Controlled Trials on the Prevalence of Statin Intolerance.
    (Am J Cardiol, 2017-09-01) Riaz, Haris; Khan, Abdur Rahman; Khan, Muhammad Shahzeb; Rehman, Karim Abdur; Alansari, Shehab Ahmad Redha; Gheyath, Bashaer; Raza, Sajjad; Barakat, Amr; Luni, Faraz Khan; Ahmed, Haitham; Krasuski, Richard A
    The prevalence of intolerance varies widely. Stopping statin therapy is associated with worse outcomes in patients with cardiovascular disease. Despite extensive studies, the benefits and risks of statins continue to be debated by clinicians and the lay public. We searched the PubMed, Medline, and Cochrane Central Register of Controlled Trials (CENTRAL) databases for all randomized controlled trials of statins compared with placebo. Studies were included if they had ≥1,000 participants, had patients who were followed up for ≥1 year, and reported rates of drug discontinuation. Studies were pooled as per the random effects model. A total of 22 studies (statins = 66,024, placebo = 63,656) met the inclusion criteria. The pooled analysis showed that, over a mean follow-up of 4.1 years, the rates of discontinuation were 13.3% (8,872 patients) for statin-treated patients and 13.9% (8,898 patients) for placebo-treated patients. The random effects model showed no significant difference between the placebo and statin arms (odds ratio [OR] = 0.99, 95% confidence interval [CI] = 0.93 to 1.06). The results were similar for both primary prevention (OR = 0.98, 95% CI = 0.92 to 1.05, p = 0.39) and secondary prevention (OR = 0.92, 95% CI = 0.83 to 1.05, p = 0.43) studies. The pooled analysis suggested that the rates of myopathy were also similar between the statins and placebos (OR = 1.2, 95% CI = 0.88 to 1.62, p = 0.25). In conclusion, this meta-analysis of >125,000 patients suggests that the rate of drug discontinuation and myopathy does not significantly differ between statin- and placebo-treated patients in randomized controlled trials. These findings are limited by the heterogeneity of results, the variable duration of follow-up, and the lower doses of statins compared with contemporary clinical practice.

    Optimal management of Riata leads with no known electrical abnormalities or externalization: a decision analysis.
    (Journal of cardiovascular electrophysiology, 2015-02) Pokorney, Sean D; Zhou, Ke; Matchar, David B; Love, Sean; Zeitler, Emily P; Lewis, Robert; Piccini, Jonathan P

    Introduction

    Riata and Riata ST implantable cardioverter-defibrillator (ICD) leads (St. Jude Medical, Sylmar, CA, USA) can develop conductor cable externalization and/or electrical failure. Optimal management of these leads remains unknown.

    Methods and results

    A Markov model compared 4 lead management strategies: (1) routine device interrogation for electrical failure, (2) systematic yearly fluoroscopic screening and routine device interrogation, (3) implantation of new ICD lead with capping of the in situ lead, and (4) implantation of new ICD lead with extraction of the in situ lead. The base case was a 64-year-old primary prevention ICD patient. Modeling demonstrated average life expectancies as follows: capping with new lead implanted at 134.5 months, extraction with new lead implanted at 134.0 months, fluoroscopy with routine interrogation at 133.9 months, and routine interrogation at 133.5 months. One-way sensitivity analyses identified capping as the preferred strategy with only one parameter having a threshold value: when risk of nonarrhythmic death associated with lead abandonment is greater than 0.05% per year, lead extraction is preferred over capping. A second-order Monte Carlo simulation (n = 10,000), as a probabilistic sensitivity analysis, found that lead revision was favored with 100% certainty (extraction 76% and capping 24%).

    Conclusions

    Overall there were minimal differences in survival with monitoring versus active lead management approaches. There is no evidence to support fluoroscopic screening for externalization of Riata or Riata ST leads.
