The Case Files: When a Spade is Not a Spade
Turrin, Danielle DO; Sattler, Steven DO; Amodeo, Dana DO A 25-year-old Hispanic man presented to the emergency department with a complaint of three days of left-sided precordial chest pain. He described the pain as a constant 6/10 with pressure-like discomfort radiating to his left arm and the left side of his neck. He also experienced nausea, but denied any provocative or palliative factors. He said he had not experienced anything similar to this before. He had no family history of heart disease, acute myocardial infarction, or sudden cardiac death. He admitted to a 1.5 pack-per-day smoking history and social alcohol us...

Hypoxia and Ischemia-Reperfusion: A BiK Contribution?
Abstract Over the last decades, cardiovascular disease has become the primary cause of death in the Western world, and this trend is expanding throughout the world. In particular, atherosclerosis and the subsequent vessel obliterations are the primary cause of ischemic disease (stroke, coronary heart disease). Excess calcium influx into the cells is one of the major pathophysiological mechanisms important for ischemic injury in the brain and heart in humans. The large conductance calcium-activated K(+) channels (BK) are thus interesting candidates to protect against excess calcium influx and the events leading to ...

Calcium supplements associated with increased risk of cardiovascular death in men but not women
Commentary on: Xiao Q, Murphy RA, Houston DK, et al.. Dietary and supplemental calcium intake and cardiovascular disease mortality: the National Institutes of Health-AARP diet and health study. JAMA Intern Med 2013;173:639–46 Implications for practice and research Calcium supplements increase cardiovascular risk. The role of calcium supplements in the management of osteoporosis should be reconsidered. Context In 2008, a randomised controlled trial (RCT) suggested that calcium supplements might increase the risk of cardiovascular events.1 Subsequent meta-analyses of RCTs examining calcium monotherapy and calcium and v...

Blood pressure control and cardiovascular outcomes in normal-weight, overweight, and obese hypertensive patients treated with three different antihypertensives in ALLHAT
Objective:Epidemiologically, there is a strong relationship between BMI and blood pressure (BP) levels. We prospectively examined randomization to first-step chlorthalidone, a thiazide-type diuretic; amlodipine, a calcium-channel blocker; and lisinopril, an angiotensin-converting enzyme inhibitor, on BP control and cardiovascular outcomes in a hypertensive cohort stratified by baseline BMI [kg/m2; normal weight (BMI 30)]. Methods:In a randomized, double-blind, practice-based Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial, 33 357 hypertensive participants, aged at least 55 years, were followed...

Fibroblast Growth Factor-23 and Cardiovascular Disease in the General Population: The Multi-Ethnic Study of Atherosclerosis Original Articles
Conclusions— Higher serum FGF-23 concentrations are associated with subclinical cardiac disease and with new heart failure and coronary disease events, but not with carotid intima-media thickness or stroke. FGF-23 may be a novel cardiovascular risk factor in the general population.

Statins do not improve cardiovascular outcomes for dialysis patients
Commentary on: Palmer SC, Navaneethan SD, Craig JC, et al.. HMG CoA reductase inhibitors (statins) for dialysis patients: a systematic review and meta-analysis. Cochrane Database Syst Rev 2013;(9):CD004289. Context Chronic kidney disease affected nearly 19 million people in the USA, with incidence increasing globally at an annual rate of 8%, most of which were unrecognised or undiagnosed. Cardiovascular events are common among patients with chronic kidney disease and highest in dialysis patients. While dialysis patients experience a high prevalence of traditional risk factors for cardiovascular disease (CVD), such as hyper...

Antihypertensive treatment and risk of atrial fibrillation: a nationwide study
Conclusion Use of ACEis and ARBs compared with β-blockers and diuretics associates with a reduced risk of atrial fibrillation, but not stroke, within the limitations of a retrospective study reporting associations. This suggests that controlling activation of the renin-angiotensin system in addition to controlling blood pressure is associated with a reduced risk of atrial fibrillation.

Controversy Regarding the Association of High Calcium Intake and Increased Risk for Cardiovascular Disease
Calcium intake has been shown to be associated with beneficial effects regarding hypertension, coronary heart disease (CHD), vascular disease, and stroke by several prospective cohort studies. However, recent studies have questioned the beneficial cardiovascular effects of calcium intake and instead have shown that high calcium intake is associated with an increased risk for CHD and stroke. These findings have created controversy and concern among physicians, because calcium is consumed by a large number of older men and women to prevent osteoporosis and bone fractures. Based on the methods of patient self‐reporting of c...

The inhibitory effect of simvastatin and aspirin on histamine responsiveness in human vascular endothelial cells
Statins and aspirin deliver well-established cardiovascular benefits resulting in their increased use as combined polypills to decrease risk of stroke and heart disease. However, the direct endothelial effect of combined statin/aspirin cotreatment remains unclear. Histamine is an inflammatory mediator that increases vascular permeability, and so we examined the effect of treating human umbilical vein endothelial cells (HUVECs) for 24 h with 1 μM simvastatin and 100 μM aspirin on histamine responsiveness. Subsequent histamine (1 μM) challenge increased intracellular calcium (Ca2+i) concentration, an effect that was...

Daily calcium intake in excess of 1400 mg is associated with increased all-cause and cardiovascular disease mortality in women
Commentary on: Michaëlsson K, Melhus H, Warensjö Lemming E, et al.. Long term calcium intake and rates of all cause and cardiovascular mortality: community based prospective longitudinal cohort study. BMJ 2013;346:f228. Implications for practice and research Greater calcium intake is encouraged for bone health, but has unclear cardiovascular consequences. In a large cohort of Swedish women, total calcium intake of <600 or ≥1400 mg/day was associated with an increased risk of total mortality (TM) and cardiovascular disease mortality (CVDM). It is important to emphasise adequate dietary calcium intake in...

“De-Risking” Risk Reduction Should Coronary Artery Calcium Scoring Be the Gatekeeper to Preventive Pharmacotherapy With the Polypill? ∗
The cardiovascular disease (CVD) epidemic remains the leading cause of death worldwide (1). Widespread adoption of the Western diet and lifestyle by populations in emergent countries with low or middle income has resulted in dramatic increases in the incidence of coronary heart disease and stroke. An overwhelming proportion of the cardiovascular risk is explained by the cumulative presence of classic and potentially modifiable risk factors, and this effect does not seem to be influenced by sex, ethnicity, or geography (2). Therefore, to effectively reduce risk and improve outcomes, prevention strategies should be conducted...

Use of drug treatment for secondary prevention of cardiovascular disease in urban and rural communities of China: China Kadoorie Biobank Study of 0.5million people
Conclusions: Despite recent improvements in hospital care in China, only one in three individuals with prior CVD was routinely treated with any proven secondary preventive drugs. The treatment rates were correlated with the existence of other risk factors, in particular evidence of hypertension.

No pain, no gain? Getting the most out of exercise
Staying in shape has all sorts of benefits, from maintaining heart health to warding off dementia and cancerInactivity – fuelled by cars and a sedentary work life – has been dubbed the biggest public health problem of the 21st century, a global pandemic with dramatic impact on peoples wellbeing. The latest reports suggest that around the world it was responsible for 5.3 million deaths in 2008 – around one in 10 – more deaths than smoking.Not only does exercise make you fitter, it can also ward off numerous and often unexpected diseases, from heart attacks, to diabetes, some forms of cancer and dementia. There are t...

Lower dairy products and calcium intake is associated with adverse retinal vascular changes in older adults
Conclusions: A significant association was observed between lower intake of dairy products or calcium and adverse retinal vascular signs. We cannot discount the possibility of confounding from unmeasured risk factors; hence, further studies are warranted to confirm these findings.
