When winter comes, the temperature plummets, leading to unstable blood pressure, and the decrease in sunlight leads to a decrease in active vitamin D, which is detrimental to the diastolic function of the heart. In addition, the dry weather in the north will lead to an increase in the viscosity of our blood and slow blood flow, which may increase the possibility of atherosclerosis and lead to the formation of blood clots, resulting in heart attacks. Winter is also a hurdle for heart patients, so it is still very important for heart patients to know how to overcome this hurdle. Today we will see what heart patients should pay attention to in winter? 1, remember to take your medication on time Many heart patients often make the following mistakes in their daily medication: medication is irregular; medication is used when it develops and stopped when it does not. Heart disease, as one of the most common chronic diseases in the middle-aged and elderly, is a continuous process of occurrence and development, and should be adhered to long-term medication or even lifelong medication. Only by insisting on taking medication can we stop the occurrence and development of the disease. Patients with coronary heart disease, regardless of whether they have undergone heart stent surgery or not, need to take medication to prevent platelet aggregation, atherosclerotic plaque formation and shedding, and arterial thrombosis. 2, pay attention to monitor their blood pressure, heart rate The winter weather is cold, blood pressure and heart rate will be subject to environmental changes and fluctuations. Therefore, heart patients should pay real attention to their blood pressure, it is best to measure it every day. With good monitoring of blood pressure in order to effectively prevent the occurrence of dangerous conditions caused by high blood pressure, it is recommended to measure blood pressure once a day in the morning and once in the evening when the blood pressure condition is relatively stable, and to increase the frequency of blood pressure measurement in case of more obvious fluctuations in blood pressure to prevent and control the occurrence of accidents. 3, pay attention to their own symptoms activity or emotional excitement when the posterior sternal or precordial area dull pain, or tightness-like pain, physical activity, chest tightness, palpitations, shortness of breath, if the above situation must pay attention to whether the symptoms of coronary angina or myocardial infarction onset, must pay attention to stop activities, rest immediately, and promptly seek medical attention. 4, lifestyle can not be ignored winter is coming, in general most people will not want to move because of the cold weather, in addition to eat and more, but for heart disease patients is very unfavorable. It is necessary to take part in physical exercise properly and maintain 150 minutes of exercise time per week, the intensity of which should not produce discomfort; most importantly, attention must be paid to controlling weight and waist circumference. Avoid eating too salty and too oily. In addition, when you wake up in the morning and prepare to get up, you must first lie in bed for a while, slowly adapt to the ambient temperature, and get up slowly to avoid cold air stimulation leading to vasoconstriction causing insufficient blood supply to the heart muscle. When you go out, you should pay more attention to keep warm. 5.Regular review should not be forgotten It is recommended that patients with stable coronary artery disease see a doctor once every 1-2 months to review their blood pressure, blood lipids, blood sugar levels, in addition to whether to review the electrocardiogram examination.
