A low-cost rapid blood test can accurately rule out heart attack risk in nearly half of all patients with chest pain, saving millions from further tests and reducing healthcare costs. The test, which measures troponin levels in the blood, can identify a threshold level below which patients are unlikely to have had a heart attack.
A registry-based study from Aarhus University found that heart attack survivors are at a higher risk of developing vascular dementia, which is caused by vascular damage in the brain. The risk remains elevated for up to 35 years after the heart attack, with patients who underwent bypass surgery showing a fourfold increased risk.
