冬季的到来使得心血管疾病进入了高发期，近期有关心梗去世的新闻频繁出现在热搜上。那么，为什么寒冷的冬季会成为心血管疾病的高发时段呢？专家指出，寒冷的刺激会导致血管突然舒张或收缩，进而引发心脏供血不足，血流受阻，加大了心脏的负担。
在寒冷的冬季，人们的血压往往会上升，心率也会加快，这些都是心脏负担加重的表现。此外，冬季气温的骤降也会使得血管收缩，从而增加了心梗的发生风险。心梗患者在支架手术后，虽然病情得到了控制，但仍然需要在运动方面加以注意。
专家建议，心梗患者在支架术后应遵循医生的建议，适度进行运动。然而，寒冷的天气会使得心脏负担加重，因此在这段时间内，患者应尽量避免剧烈运动，以防心梗复发。对于心梗患者来说，冬季的保暖措施尤为重要，以降低心血管疾病的发生风险。
Title: Winter stroke and exercise after stent placement

The arrival of winter has made cardiovascular diseases enter a high-incidence period. Recently, news about stroke-related deaths has frequently appeared on hot searches. Why does winter become a high-incidence season for cardiovascular diseases? Experts point out that under the stimulation of cold weather, sudden dilation or constriction of blood vessels will occur, causing insufficient blood supply to the heart, obstructed blood flow, and increased burden on the heart.
In winter, people’s blood pressure often rises, and their heart rate also accelerates, which are manifestations of increased heart burden. In addition, the sudden drop in temperature in winter causes blood vessel constriction, further increasing the risk of myocardial infarction. After stent placement, although the condition of myocardial infarction patients has been controlled, they still need to pay attention to exercise.
Experts advise that myocardial infarction patients should follow their doctor’s advice and engage in moderate exercise after stent placement. However, cold weather makes the heart burden heavier, so patients should avoid vigorous exercise during this time to prevent myocardial infarction recurrence. For myocardial infarction patients, keeping warm in winter is particularly important to reduce the risk of cardiovascular diseases.
