Hypertension is a common treatable risk factor for cardiovascular disease. Even when identified and treated, most patients with hypertension do not get to blood pressure goal and they often need at least two antihypertensive agents to achieve blood pressure control.

Hypertension is an increasingly prevalent cardiovascular risk factor associated with high rates of morbidity and mortality. Lowering blood pressure (BP) to recommended levels reduces the risk of hypertension-associated cardiovascular events. Despite current treatment options and recommendations, the BP of many

In order to adequately control hypertension, the majority of patients will require treatment with more than one antihypertensive agent. Fixed-dose combination therapy offers several advantages, including improved efficacy, tolerability, and treatment compliance. Certain combinations have benefits in specific patient populations

Statins can regress coronary atheroma and lower clinical events. Although pre-clinical studies suggest procalcific effects of statins in vitro, it remains unclear if statins can modulate coronary atheroma calcification in vivo. This study compared changes in coronary atheroma volume and calcium indices
