Cardiovascular news covering heart disease, stroke, blood pressure, cholesterol, and cardiac treatment advances.

• Eye scans can detect atrial fibrillation years early

  Research involving over 90,000 individuals found that eye scans can identify biological markers for atrial fibrillation up to four years before clinical diagnosis. Scientists identified thinner retinal layers in patients, suggesting retinal imaging could serve as a complementary tool to electrocardiograms for early detection.

• "Common bedroom mistake could be quietly taking a toll on your health, experts say"

  A Tulane University study suggests sleeping with light exposure above three lux increases cardiovascular risks, including heart failure and stroke. Experts argue this nighttime illumination suppresses melatonin production, disrupting circadian rhythms and chronically reducing sleep quality, which negatively impacts overall health.

• "'Is 145/70 mmHg considered high blood pressure?'"

  The Indian Express article cites cardiologist Dr. Aseem Dhall to explain that a blood pressure reading of 145/70 mmHg indicates elevated systolic pressure despite normal diastolic levels. It argues that a single reading cannot confirm hypertension due to variable factors like stress, though repeated high systolic readings warrant medical attention.

• "Decoding your blood pressure numbers: What that reading really means"

  Medical experts explain that high blood pressure stems from chronic inflammation damaging the glycocalyx layer in blood vessels. The commentary argues that understanding this oxidative stress mechanism is crucial for prevention, emphasizing lifestyle changes and data monitoring to protect vascular health.

• "'Having a stroke at 26 was massive learning curve'"

  This piece highlights the case of Niamh Foster, who suffered an ischemic stroke at age 26 due to a heart defect. It argues that young adults should recognize stroke symptoms like facial drooping and aphasia, emphasizing the hidden long-term effects of recovery such as fatigue and memory difficulties.

• "KIMS Saveera performs complex emergency angioplasty"

  The article reports on a successful emergency angioplasty performed by KIMS Saveera Hospitals in India on a 90-year-old patient with chronic kidney disease. It highlights the multidisciplinary approach used to minimize contrast dye risks and emphasizes the importance of timely decision-making in complex cardiac emergencies involving elderly patients.
