Study Shows Value of Calcium Scan in Predicting Heart Attack and Stroke Among Those Considered at Either Low or High Risk - 12/23/13
A new study shows that coronary artery calcium (CAC) screening, an assessment tool that is not currently recommended for people considered at low risk, should play a more prominent role in helping determine a person’s risk for heart attack and heart disease-related death, as well as the need for angioplasty or bypass surgery.

Study shows value of calcium scan in predicting heart attack, stroke among those considered at risk
(Johns Hopkins Medicine) A new study shows that coronary artery calcium (CAC) screening, an assessment tool that is not currently recommended for people considered at low risk, should play a more prominent role in helping determine a person's risk for heart attack and heart disease-related death, as well as the need for angioplasty or bypass surgery. CAC screening provides a direct measure of calcium deposits in heart arteries and is easily obtained on a computed tomography scan.

Risk factors for prehypertension in the community: A prospective analysis from the Western New York Health Study
Conclusions: Results from this study suggest early dysregulation of glucose metabolism and weight gain over the lifespan may represent important risk factors for prehypertension in the general population.

Density of CAC Has Role in Heart Risk (CME/CE)
(MedPage Today) -- The density of calcium in coronary artery plaque is inversely and significantly associated with heart disease and stroke risk independent of calcium volume and should be considered whenever calcium scanning is used to assess patient risk, researchers reported.

Scan could detect those on brink of heart attack
Conclusion
This is a valuable study which shows the promise of using PET-CT with radioactively labelled sodium fluoride (NaF) as a way of identifying fatty deposits in the heart arteries that could be at risk of rupturing and causing a heart attack. The results confirmed that the marker used in this study (NaF) was better than the chemical marker normally used in PET-CT scans (FDG).
The technique has the principal value of being a non-invasive technique compared with coronary angiography, which is the standard method used to look at blockages in heart arteries. As it does not involve surgical intervention, this could ha...

Effect of Middle Cerebral Artery Territory Ischemic Stroke on QT Interval
In this study, we investigated whether QT interval dynamics is different in patients with right and left middle cerebral artery (MCA) territory stroke.Method: Electrocardiogram (ECG) intervals were compared between baseline (retrieved retrospectively from medical records) and admission (acquired at the acute hospital admission) in 33 patients (65 ± 9.5 years) with right or left MCA territory ischemic stroke. Head computed tomography (CT), cardiac ultrasound, and cardiac CT scans were undertaken.Results: Stroke was located in the right MCA territory in 21 (64%) and in the left MCA territory in 12 (36%) patients. Patients w...

Having "the talk" when heart disease runs in the family
When heart disease or stroke runs in a family, it's important to talk about it with children and other close family members. The conversation may be hard, but the payoff—better health for all—can be huge, according to the September 2013 Harvard Heart Letter.
"Knowing your family history is one of most powerful tools we have to guide how we take care of ourselves from a health perspective," says Dr. Paula A. Johnson, professor of cardiology at Harvard Medical School and chief of the Division of Women's Health at Brigham and Women's Hospital. "This is a chance for your children to make changes that will have both...

Leukocyte telomere length and coronary artery calcification in Palestinians
We examined the association of LTL with coronary artery calcification (CAC), which reflects the cumulative burden of coronary atherosclerosis, in an urban Arab sample of Palestinians, a population at high risk of CHD.Methods: Using a cross-sectional design, a random sample of East Jerusalem residents, comprising 250 men aged 45–77 and women aged 55–76 and free of CHD or past stroke, was drawn from the Israel national population register. LTL was measured by Southern blots. CAC was determined by 16-slice multidetector helical CT scanning using Agatston scoring. We applied multivariable logistic modeling to examine the a...

No proof heading footballs causes brain damage
Conclusion
Overall, this research provides no evidence that there is a direct cause and effect between repeated heading of a football and traumatic brain injury. However, there are several important limitations to this study that are worth noting.
One-off tests and scans of players
The people in the study only had brain images and neurological tests at one point in time, and were asked about heading in the previous year and if they had any concussions in their lifetime.
Without having the imaging and neurological tests prior to the year in question – or preferably in early periods of life, before they started playing f...

No evidence Nordic diet prevents heart disease
Conclusion
This was a well-designed randomised controlled trial that took place across several Nordic locations. The study took careful clinical measures of elements of metabolic syndrome at several points during the trial, and used food diaries at regular intervals to check compliance to the assigned diet.
However, it provides no reliable proof that the ‘healthy’ Nordic diet is any better than the ‘average’ Nordic diet at improving components of metabolic syndrome and, in turn, no proof that it reduces the risk of cardiovascular disease.
Importantly, this study found no significant results for its main aim (which...

Leukoaraiosis is Associated with Short- and Long-term Mortality in Patients with Intracerebral Hemorrhage
Conclusions: In unselected patients in Southern Norway with first-ever ICH, severe leukoaraiosis is independently associated with both 30-day and long-term mortality in 30-day survivors. Warfarin is independently associated with 30-day mortality and coronary heart disease with long-term mortality in 30-day survivors. Recurrent ICH is more frequent after lobar ICH than after ICH in other locations.

Secondhand smoke linked to dementia
Conclusion
Secondhand or passive smoking is known to be detrimental to health and has been associated with increased risk of cardiovascular diseases and cancer. However, it is not yet certain whether it is linked to dementia.
Though this large study finds a significant link between secondhand smoke exposure and severe dementia syndromes there are several important limitations to be aware of.
Problems with measuring dementia diagnoses
The method for diagnosis of dementia used by this study was unusual. Though the researchers assessed each individual using a mental state examination, they went on to diagnose them using a com...

Very long-term mortality after ischemic stroke: : predictors of cardiovascular death.
This study shows that age, male gender, stroke severity, hemorrhagic stroke, diabetes, ischemic heart disease, and right hemispheric stroke are predictors associated with increased risk of long-term cardiovascular mortality. Neither atrial fibrillation, antihypertensive treatment on admission, smoking, or living alone was risk factors for late cardiovascular deaths.

Accidental hypothermia and local cold injury: physiological and epidemiological studies on risk
ConclusionsHypothermia and cold injury continue to cause injury and hospitalisation in the northern region of Sweden. Assessment and management is not standardised across hospitals. With the identification of groups at high risk for fatal hypothermia, it should be possible to reduce the incidence, particularly for highest risk subjects: rural, living alone, alcohol imbibing, and psychiatric diagnosis‐carrying citizens. Long‐term cold‐weather training may affect hand‐rewarming patterns after a cold provocation, and a warmer baseline hand temperature with faster rewarming after a cold provocation may be associated wi...
