Screening for Cardiovascular Disease Risk with Electrocardiography [Putting Prevention into Practice]
A 55-year-old man presents for an annual visit. He has no history of hypertension, cardiovascular disease (CVD), or diabetes mellitus; has never smoked; and has no family history of CVD. His lipid panel results from one year ago were normal, and he has no current symptoms of CVD.

Blood Pressure Targets for Patients with Hypertension and Cardiovascular Disease [Cochrane for Clinicians]
Achieving a target BP of 135/85 mm Hg or less does not decrease the risk of total cardiovascular events vs. treating to a target of 140 to 160/90 to 100 mm Hg. Further, treating to the lower BP target does not improve total mortality, cardiovascular mortality, or serious adverse effects.
What is the effect of omega-3 fatty acid supplementation on cardiovascular outcomes?
Prescription niacin (nicotinic acid, vitamin B3) does not reduce myocardial infarctions, strokes, or overall mortality when used for primary or secondary prevention.
A cardiac troponin I concentration of less than 5 ng per L in adults who present with potential acute coronary syndrome has a negative predictive value (NPV) of at least 99.9% for cardiac death at 30 days and at one year.
In patients with suspected MI and normal oxygen levels, giving immediate supplemental oxygen therapy does not improve mortality at one year. Although this study was underpowered because of fewer than expected deaths in the control group, the results were consistent across all subgroups, as well as with findings from other literature.

Statin Use for the Primary Prevention of Cardiovascular Disease in Adults [Putting Prevention into Practice]
L.D., a 66-year-old generally healthy white man, presents for his annual physical. He has no history of cardiovascular disease (CVD); he has had consistent systolic blood pressure measurements of 140 mm Hg; he is not taking any medications; he does not smoke; he exercises three times per week; and his body mass index is 25 kg per m2.
History of a collapse can be the first and only indication of hypertrophic cardiomyopathy. This athlete's story is a reminder that during preparticipation sports examinations, a detailed history may provide the only clue to a potentially lethal underlying cardiac condition.
