In recent days, most parts of China have experienced significant cooling, resulting in an increase in indoor and outdoor temperature differences. Sudden changes in temperature can be particularly dangerous for patients with cardiovascular and cerebrovascular diseases. What should these patients pay attention to? Let's listen to the expert's advice.
The doctor explained that every winter, the number of myocardial infarction patients in the hospital increases significantly because the cold air can cause blood vessels to spasm, increase blood viscosity, and lead to unstable blood pressure, which can cause plaque rupture and thrombus formation in the blood vessels, leading to the occurrence of myocardial infarction.
For patients with coronary heart disease, if they experience symptoms such as compression of the heart, chest pain, and tightness, they need to be alert to the worsening of angina symptoms.
For patients with heart failure, it is important to note that if they experience a significant decrease in exercise ability after exposure to cold air, accompanied by symptoms such as chest tightness, shortness of breath, difficulty breathing, nighttime wheezing, and lower limb edema, attention should be paid to the worsening of the heart failure condition.
For patients with hypertension, regardless of any discomfort symptoms, blood pressure should be measured daily during seasonal changes. If a cardiovascular patient experiences an emergency at home, emergency medication can be taken.
In addition, experts suggest that sudden drops in temperature and constriction of blood vessels may also lead to insufficient blood supply to the brain, causing stroke. It can be distinguished by examining symptoms such as facial symmetry, unilateral weakness in the arms, and clear speech. For acute ischemic stroke, patients should strive to undergo intravenous thrombolysis within the "golden treatment window" of 4.5 hours of onset to restore blocked blood vessels and reduce brain damage.
