“This study involved a genetic analysis of the blood types of nearly 17,000 people who'd had a stroke. They found that people with blood type A had an increased risk of an early stroke (between 18 and 60). Those with blood type O had a decreased risk, with people who have type B or AB somewhere in the middle.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
People with blood types A and B may have higher risks for developing dangerous blood clots compared to people who have type O blood. That's according to new research that also showed a slightly higher risk for certain types of heart disease among the A and B groups.
Age — People age 55 or older have a higher risk of stroke than do younger people. Race or ethnicity — African Americans and Hispanics have a higher risk of stroke than do people of other races or ethnicities. Sex — Men have a higher risk of stroke than do women.
The major risk factors for stroke include: High blood pressure. Diabetes. Heart and blood vessel diseases: Conditions that can cause blood clots or other blockages include coronary heart disease, atrial fibrillation, heart valve disease, and carotid artery disease.
Call 9-1-1 immediately if any of these signs of stroke appear: Numbness or weakness in the face, arm, or leg; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Trouble walking, dizziness, or problems with balance; severe headache with no known cause.
It can be caused by a narrowed blood vessel, bleeding, or a clot that blocks blood flow.
High blood pressure.
It's the biggest cause of strokes.
Foods high in potassium, such as sweet and white potatoes, bananas, tomatoes, prunes, melon and soybeans, can help you maintain a healthy blood pressure — the leading risk factor of stroke. Magnesium-rich foods, such as spinach, are also linked to a lower risk of stroke.
Here's one finding that has continued to surface over the years: People with a non-O blood type (that's A, B, or AB) are at a higher risk of developing cardiovascular diseases.
Blood group AB has the strongest contact to pathogen and is the least protected group with respect to innate ABO(H) immunity.
From these findings, the authors concluded that blood group B might be associated with exceptional longevity. The association of ABO blood type with health and longevity should not be surprising.
Taken together, the authors concluded that type O and Rh-negative blood groups may be protective against SARS-CoV-2 infection and illness.
Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there's a limited supply of the exact matching blood type. That's because type O negative blood cells don't have antibodies to A, B or Rh antigens.
Drink a lot of water: You should drink at least five glasses of water per day, and this will reduce your risk of stroke by 53%, according to a recent study by Loma Linda University.
Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke. One study found that 43% of stroke patients experienced mini-stroke symptoms up to a week before they had a major stroke.
The majority of strokes occur in people who are 65 or older. As many as 10% of people in the U.S. who experience a stroke are younger than 45. How do the symptoms of stroke in young people differ from those in the older age group?
Stress can cause the heart to work harder, increase blood pressure, and increase sugar and fat levels in the blood. These things, in turn, can increase the risk of clots forming and travelling to the heart or brain, causing a heart attack or stroke.
Low doses of aspirin — such as 75 to 100 milligrams (mg), but most commonly 81 mg — can be effective at preventing heart attack or stroke.
Even after surviving a stroke, you're not out of the woods, since having one makes it a lot more likely that you'll have another. In fact, of the 795,000 Americans who will have a first stroke this year, 23 percent will suffer a second stroke.
Although strokes most frequently are caused by factors such as uncontrolled high blood pressure, there also are other rare conditions that may lead to stroke. Many of these conditions are hereditary, meaning they are passed down through family lines.
