If left undiagnosed and uncontrolled, high blood pressure can lead to heart attack, enlargement of the heart and eventually heart failure. (who.int)
2. By definition, CVDs affect the heart and the blood vessels of the body. (who.int)
What happens in the heart when one of the larger coronary arteries gets blocked in a heart attack? (lu.se)
We have investigated what sort of microRNAs are present in patients with severe heart attacks and compared this with healthy individuals", says Olof Gidlöf, who is the principal author of the study, published in the journal Blood. (lu.se)
Some microRNAs are specific to the heart muscle, while others are only found in the coronary arteries, etc.", explains Olof Gidlöf. (lu.se)
We were interested in finding out what happens in the blood clot that forms in the heart in the case of a heart attack, so we studied microRNAs in blood platelets. (lu.se)
This prevents the heart muscle from getting sufficient blood, leading to a heart attack. (lu.se)
Our hypothesis was that the blood platelets which were activated in conjunction with the heart attack had emptied their content of microRNAs and that that was the explanation behind the lower values in the heart attack patients", explains Olof Gidlöf. (lu.se)

The clinical examination includes a series of questionnaires, which measure demographic, lifestyle, and psychological factors (e.g., depression, post-traumatic stress), DEXA measurements to record bone density and body composition, ultrasounds of the brachial and carotid arteries, 18 salivary cortisol samples throughout the day and in response to a series of challenges, and blood samples.

Cervical artery dissections are a significant cause of strokes in young adults. (wikipedia.org)
Cervical artery dissection has been noted to be a common cause of young adult strokes, with some sources indicating a prevalence of up to 20% in this young adult population with annual incidence rates between 2.6 and 2.9 per 100,000, although these incidences may be misleading with true incidences being higher because clinical presentations can vary, many being minor or self-limited, and thus these dissections can go undiagnosed.
