ReviewNoninvasive Imaging for the Asymptomatic Patient: How to Use Imaging to Guide Treatment Goals?
Imaging subclinical atherosclerosis identifies individuals at higher risk of cardiovascular disease through direct visualization before events occur so that preventative measures can be taken. Coronary artery calcium (CAC) scans are the most widely used and studied to identify subclinical atherosclerosis and are most useful in men older than 40 years and women older than 50 years. Coronary computed tomography angiography has high prognostic value and might be the best modality for assessing subclinical atherosclerosis with incremental increase in predictive value over CAC. Ankle-brachial indexes are specific markers for cardiovascular risk but are a less sensitive tool for risk assessment.

The treatment of elevated blood pressure (BP) can improve cardiovascular (CV) event rates. Current BP targets depend on expected CV event rates in individuals as assessed by concurrent medical conditions and other risk factors. Importantly, the means by which BP is measured has evolved. This evolution is driven by recognition that techniques different than routine office BP measurements can provide a better assessment of future CV risk.

ReviewCardio-Rheumatology: Prevention of Cardiovascular Disease in Inflammatory Disorders.
Inflammation plays a well-established role in the development and progression of atherosclerosis. Individuals exposed to chronic inflammation are at an increased risk of developing cardiovascular disease, including coronary artery disease and heart failure, independent of associated traditional risk factors. ⋯ In addition to this, there is a lack of awareness on the association between inflammation and cardiovascular disease. These factors lead to undertreatment in terms of preventive cardiac care in patients with chronic inflammatory disease.

This review highlights the key components of a heart-healthy diet and presents an evidence-based overview of recent research. Diets that increase plant-based food sources and healthy unsaturated fats consumption and limit foods that are processed and/or high in sodium, refined sugar, and saturated fat are recommended. Dietary modification can be supplemented with lifestyle-based therapies (eg, exercise, time-restricted eating) to maximize clinical benefit and achieve the "cardiometabolic jackpot." Physicians should take into account cultural preferences, affordability and accessibility of foods, and their patients' cultural values or expectations when recommending dietary interventions.

Hypertension is a major cause of cardiovascular morbidity and mortality globally. Many patients with hypertension have secondary causes of hypertension that merit further evaluation. ⋯ However, secondary hypertension is often underrecognized. The goal of this review is to highlight optimal approaches to the diagnosis and management of common causes of secondary hypertension, including primary aldosteronism, renovascular hypertension, obstructive sleep apnea, and drug-induced hypertension.
