Control of cardiovascular (CV) risk factors, particularly hypertension, is still unsatisfactory, resulting in excess CV morbidity and mortality worldwide. CV risk is linearly associated with an increase in blood pressure (BP) values, and clinical studies have clearly demonstrated that BP lowering represents the most effective means of preventing CV events. However, while BP reduction is a fairly easy target, BP normalization is much more difficult to achieve, and adequate BP control (<140/90 mmHg) is attained only in a small percentage of the hypertensive population.

Providing further support for the recommendation to eat plenty of dietary fiber, a new large prospective cohort study shows that fiber intake is associated with a significantly reduced risk of total death, including cardiovascular mortality and deaths from infectious and respiratory diseases [1].

Ischemic heart disease (IHD) is the leading cause of death among women in the Western world, and its prevalence is growing.
Women with chest pain and abnormal stress tests are less likely than men to have critical stenosis of coronary arteries, a phenomenon attributed to endothelial dysfunction. Hypertension, intimal injury, and cholesterol are among the various factors that contribute to endothelial dysfunction.

Global mortality rates from COPD are projected to increase by 30% over the next decade, and by 2030, COPD will be the third leading cause of death, Primary care clinicians often are the first providers to see a patient with COPD and may be the only clinicians to treat those patients.
Accurate diagnosis, particularly differentiation from asthma, is the cornerstone of effective management. Spirometric assessment is the best and most accurate method for diagnosing COPD. Spirometry should be performed before and after bronchodilator therapy: if the patient has asthma, the forced expiratory volume in 1 second (FEV1) usually returns to normal after therapy, whereas in COPD “values rarely, if ever, return to normal.” Yet spirometry is underused in primary care practices.

The use of calcium supplements without co-administered vitamin D is associated with an increased risk of MI
Most guidelines for the prevention or treatment of osteoporosis recommend the use of calcium supplements, despite the fact that they reduce the risk of fracture only marginally
Studies have yielded conflicting results about their use, with some observational studies suggesting that high calcium intake is protective against vascular disease, and others showing that calcium supplements speed vascular calcification and increase mortality in patients with kidney failure and increase cardiovascular events and MI in women.
