Stroke, commonly known as “stroke”, is caused by blood circulation disorders caused by vascular lesions in the brain, including ischemic stroke and hemorrhagic stroke. Half of all ischemic strokes are caused by hypertension, which promotes the deposition of lipids on the arterial walls, forming lipid plaques like millet porridge, causing arterial elasticity to decrease and the lumen to narrow; on the other hand, hypertension also promotes plaque rupture, leading to thrombosis. In addition, hypertension is a common cause of hemorrhagic stroke. Long-term hypertension can make the cerebral blood vessels fragile, and the fragile vessels can rupture when the blood pressure is too high. Therefore, the health of the brain can only be protected by ensuring an adequate blood supply to the blood vessels of the brain tissue and a stable blood pressure. Blood pressure fluctuates over a 24-hour period, and early morning hours are the highest time of day for different types of hypertension. The rate of stroke events is also highest in the early morning hours, so good control of early morning blood pressure can effectively reduce the occurrence of stroke. Early morning blood pressure refers to the blood pressure measured between 6:00 a.m. and 10:00 a.m. after waking up (before taking medication and before breakfast). The key points for home self-measurement of early morning blood pressure are: measure within 30-60 minutes after waking up, usually between 6-10:00 a.m.; measure before taking medication, which can truly reflect how well blood pressure is controlled; measure after urination, as holding urine can raise blood pressure. How can we control the early morning blood pressure? Choose long-acting antihypertensive drugs: half-life of 24h and above, eat once a day, antihypertensive efficacy can cover 24 hours of antihypertensive drugs; do not exercise strenuously in the early morning, and maintain a comfortable mood; long-term healthy lifestyle: low salt diet, limit total calories and balanced nutrition, moderate exercise, weight control, avoid overweight and obesity, quit smoking and limit alcohol. So, friends, if you want to smoothly control the early morning blood pressure, away from stroke, we have to remember the following recipe: early morning blood pressure is the most important, 6 to 10 o’clock to remember, measured blood pressure and then take drugs, long-acting drugs to protect the heart and brain.
