Women more likely to have 'typical' heart attack symptoms than men

Wed, 08/21/2019 - 08:22
Women who have heart attacks experience the same key symptoms as men, quashing one of the reasons given for women receiving unequal care. The research puts into question a long-held medical myth that women tend to suffer unusual or 'atypical' heart attack symptoms, and emphasizes the need for both sexes to recognize and act on the warning signs.

Type 2 diabetes may affect heart structure and increase complications and death among heart failure patients of Asian ethnicity

Wed, 08/21/2019 - 08:22
The combination of heart failure and Type 2 diabetes can lead to structural changes in the heart, poorer quality of life and increased risk of early death, according to a multi-country study in Asia.

Brain takes a beating as arteries age

Tue, 08/20/2019 - 08:18
Researchers have presented a model that explains why memory deteriorates as the body ages. With age, the brain receives an increased load from the heart's beating as the body's large arteries stiffen over the years, causing damage to the smallest blood vessels in the brain.

Regulating blood supply to limbs improves stroke recovery

Mon, 08/19/2019 - 13:21
Cutting off and then restoring blood supply to a limb following a stroke reduces tissue damage and swelling and improves functional recovery, according to a new study.

Insomnia tied to higher risk of heart disease and stroke

Mon, 08/19/2019 - 08:24
Data from more than a million people found that genetic liability to insomnia may increase the risk of coronary artery disease, heart failure and stroke. Among types of ischemic stroke, genetic liability to insomnia was primarily associated with an increased risk of large artery stroke.

Prescription omega-3 fatty acid medications effectively lower high triglycerides

Mon, 08/19/2019 - 08:24
Four grams per day of prescription omega-3 fatty acid medication effectively lower high triglyceride levels, but identification of secondary causes of high triglycerides, such as hypothyroidism and poorly managed type 2 diabetes as well as lifestyle changes should be addressed before prescribing drugs.

'Silent' strokes common after surgery, linked to cognitive decline

Thu, 08/15/2019 - 21:27
The study found that 'silent' covert strokes are actually more common than overt strokes in people aged 65 or older who have surgery.

Abnormal blood pressure in middle and late life influences dementia risk

Wed, 08/14/2019 - 08:12
In a study that spanned two and a half decades and looked at data from more than 4,700 participants, researchers have added to evidence that abnormal blood pressure in midlife persisting into late life increases the likelihood of developing dementia. Although not designed to show cause and effect, the study suggests that maintaining a healthy blood pressure throughout life may be one way to help decrease one's risk of losing brain function.

Aerobic exercise programs may improve endurance, walking after stroke

Wed, 08/14/2019 - 08:11
Stroke survivors who completed a group-based aerobic exercise program, like cardiac rehabilitation, significantly improved their endurance and walking capacity regardless of time since stroke. Mixed forms of aerobic activity and walking had the most benefit for stroke survivors.

Greater blood pressure control linked to better brain health

Tue, 08/13/2019 - 13:04
For adults with high blood pressure, greater blood pressure control than what's currently considered standard is associated with fewer adverse changes of the brain, which could mean lower risks of dementia and cognitive impairment.

New target found for disease of the heart's smallest blood vessels

Mon, 08/12/2019 - 10:28
When we race walk, for example, part of our healthy heart muscle may want a little more blood and oxygen, so our tiniest blood vessels send a message upstream to the larger vessels to send more. Researchers have found that a chemical in our bodies known to help blood vessels dilate also sends that signal to the larger blood vessels that more blood is needed.

Fast food availability linked with more heart attacks

Mon, 08/12/2019 - 09:44
Areas with a higher number of fast food restaurants have more heart attacks, according to new research. The study also found that for every additional fast food outlet, there were four additional heart attacks per 100,000 people each year.
