Purpose Of Review: Elevated blood pressure is the leading modifiable risk factor for cardiovascular morbidity and mortality in the US. Older individuals, Black adults, and those with comorbidities such as chronic kidney disease, have higher levels of uncontrolled and resistant hypertension. This review focuses on resistant hypertension, specifically in the US Black population, including potential benefits and limitations of current and investigational agents to address the disparate toll.

Background: Subclinical hypertensive heart disease (SHHD) is a precursor to heart failure. Blood pressure (BP) reduction is an important component of secondary disease prevention in patients with SHHD. Treating patients with SHHD utilizing a more intensive BP target (120/80 mm Hg), may lead to improved cardiac function but there has been limited study of this, particularly in African Americans (AAs).

Purpose Of Review: The purpose of this review is to examine the impact and effectiveness of community interventions for controlling hypertension in African-Americans. The questions addressed are as follows: Which salient prior and current community efforts focus on African-Americans and are most effective in controlling hypertension and patient-related outcomes? How are these efforts implemented and possibly sustained?

Recent Findings: The integration of out-of-office blood pressure measurements, novel hypertension control centers (i.e.

Blacks are two to three times as likely as whites to die of preventable heart disease and stroke. Declines in mortality from heart disease have not eliminated racial disparities. Control and effective treatment of hypertension, a leading cause of cardiovascular disease, among blacks is less than in whites and remains a challenge.

The treatment of essential hypertension is one of the most critical interventions to decrease cardiovascular morbidity and mortality. The prevalence of hypertension in the US varies across race/ethnicity with African Americans having the highest prevalence and overall less control among racial/ethnic minorities compared with non-Hispanic whites. Therapeutic lifestyle modifications are the bedrock of essential hypertension control, but most patients with hypertension will require pharmacotherapy, usually with multiple medications often in combination.

Medication nonadherence, a major problem in cardiovascular disease (CVD), contributes yearly to approximately 125,000 preventable deaths, which is partly attributable to only about one-half of CVD patients consistently taking prescribed life-saving medications. Current interest has focused on how labeling and education influence adherence. This paper summarizes the scope of CVD nonadherence, describes key U.

Predicting blood pressure (BP) response to antihypertensive therapy is challenging. The therapeutic intensity score (TIS) is a summary measure that accounts for the number of medications and the relative doses a patient received, but its relationship to BP change and its utility as a method to project dosing equivalence has not been reported. We conducted a prospective, single center, randomized controlled trial to compare the effects of Joint National Committee (JNC) 7 compliant treatment with more intensive (<120/80 mm Hg) BP goals on left ventricular structure and function in hypertensive patients with echocardiographically determined subclinical heart disease who were treated over a 12-month period.

Objectives: Poorly controlled hypertension (HTN) is extremely prevalent and, if left unchecked, subclinical hypertensive heart disease (SHHD) may ensue leading to conditions such as heart failure. To address this, we designed a multidisciplinary program to detect and treat SHHD in a high-risk, predominantly African American community. The primary objective of this study was to determine the cost-effectiveness of our program.

Latent tuberculosis infections (LTBI) contain a significant reservoir for future epidemics. Screening of health care workers (HCWs) in a high-risk tuberculosis (TB) environment is an important strategy in TB control. The study aimed to assess the prevalence of LTBI among high risk Egyptian HCWs and to assess infection associated risk factors.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a serine protease that binds to low-density lipoprotein receptors (LDL-Rs), leading to their accelerated degradation and increased low-density lipoprotein cholesterol (LDL-C) levels. Therefore, PCSK9 levels play a critical role in cholesterol metabolism by reducing LDL-R levels and thus increasing levels of plasma LDL-C. Recently, investigational agents inhibiting PCSK9 have been shown to lower LDL-C and also, potentially, an important secondary target, lipoprotein(a).

Background: As of 2012, nearly 10% of Americans had diabetes mellitus. People with diabetes are at approximately double the risk of premature death compared with those in the same age groups without the condition. While the prevalence of diabetes has risen across all racial/ethnic groups over the past 30 years, rates are higher in minority populations.

Although several risk factors contribute to cardiovascular disease (CVD) overall, hypertension (HTN) is the major controllable risk factor. Hypertension is disproportionately more prevalent among Blacks or African-Americans compared with other race/ethnic populations, and the control rates among this disparate population are alarming. Several pathophysiologic mechanisms have been demonstrated and evaluated among hypertensives and the conglomeration of genetics, environmental, and personal lifestyle activities concurrently impact the progression of hypertension-related comorbidities (i.

Cardiovascular disease (CVD), including heart disease and stroke, is the leading cause of death in the USA, regardless of self-determined race/ethnicity, and largely driven by cardiometabolic risk (CMR) and cardiorenal metabolic syndrome (CRS). The primary drivers of increased CMR include obesity, hypertension, insulin resistance, hyperglycemia, dyslipidemia, chronic kidney disease as well as associated adverse behaviors of physical inactivity, smoking, and unhealthy eating habits. Given the importance of CRS for public health, multiple stakeholders, including the National Minority Quality Forum (the Forum), the American Association of Clinical Endocrinologists (AACE), the American College of Cardiology (ACC), and the Association of Black Cardiologists (ABC), have developed this review to inform clinicians and other health professionals of the unique aspects of CMR in racial/ethnic minorities and of potential means to improve CMR factor control, to reduce CRS and CVD in diverse populations, and to provide more effective, coordinated care.

The role of antihypertensive therapy in reducing the risk of cardiovascular complications such as heart failure is well established, but the effects of different blood pressure goals on patient-perceived health status has not been well defined. We sought to determine if adverse effects on perceived health status will occur with lower blood pressure goals or more intensive antihypertensive therapy. Data were prospectively collected as a part of a single center, randomized controlled trial designed to evaluate standard (Seventh Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure-compliant) versus intense (<120/80 mm Hg) blood pressure goals for patients with uncontrolled hypertension and subclinical hypertensive heart disease.

Community hypertension (HTN) outreach seeks to improve public health by identifying HTN and cardiovascular disease (CVD) risks. In the 1980s, the National Heart, Lung, and Blood Institute (NHLBI) funded multiple positive community studies. Additionally, the Centers for Disease Control and Prevention's (CDC's) Racial and Ethnic Approaches to Community Health (REACH) program addresses CVD risks.

In patients with hypertension, 24-hour blood pressure control is the major therapeutic goal. The number of daily doses is one characteristic of an antihypertensive agent that may affect the adequacy of 24-hour control. One measure of therapeutic coverage is the 24-hour trough-to-peak ratio, which determines the suitability of an agent for once-daily administration.
