Stroke: Prolonged cerebral ischemia causes a blockage or interruption of blood flow to the brain, leading to the gradual death of nerve cells. When a blood clot forms or a cerebral blood vessel ruptures, the patient may suddenly collapse, experience hemiplegia, coma, and even death in a very short time.
Myocardial infarction: When blood circulation is disrupted due to cerebral ischemia, the heart has to work overtime to pump blood to the brain. Over time, this can cause arrhythmias, coronary artery blockage, and lead to a dangerous myocardial infarction.
Heart failure: Prolonged cerebral ischemia disrupts the body's cardiovascular regulatory system. The heart gradually weakens, becoming unable to pump blood to vital organs, putting the patient at risk of sudden death.
Malignant hypertension: When the brain does not receive enough blood and oxygen, the body reacts by increasing blood pressure to compensate. This prolonged condition can cause rupture of cerebral blood vessels or other large blood vessels, leading to extremely dangerous cerebral hemorrhage.
Brain atrophy – memory impairment: Insufficient blood flow to the brain prevents nerve cells from receiving enough oxygen and nutrients. Over time, brain cells begin to degenerate and die, especially in the memory region, causing memory loss, confusion, and potentially progressing to dementia.
Severe immune deficiency: When blood circulation and the central nervous system are affected, the body's ability to regulate immunity also decreases. Patients are more susceptible to severe infections, sepsis, and have a high risk of death if not treated promptly.
