Heart failure disease

Heart failure is a common disease in the elderly, the final complication of all hypertensive and other systemic diseases. In essence, heart failure is a condition in which the heart muscle cannot meet the needs of the circulating blood supply. Heart failure can be chronic or acute.

Signs of the disease are shortness of breath when exertion or lying down, fatigue, leg swelling, palpitations, heart palpitations… Heart failure due to many causes: untreated high blood pressure; ischemic cardiomyopathy; heart attack; heart valve disease (stenosis, mitral regurgitation, aortic regurgitation); congenital heart disease not corrected by surgery (pulmonary stenosis, ductus arteriosus...); Myocarditis; untreated hyperthyroidism; chronic kidney failure; Persistent arrhythmia…

Regardless of the stage of heart failure and at any time of the year, the patient still has to regularly take medication as prescribed by the doctor. However, the hot summer weather makes the body lose more water through excretion, leading to water and electrolyte disorders. At that time, electrolytes such as sodium, calcium, and potassium all decrease, causing the patient to have complications such as arrhythmia, kidney failure (because the kidneys do not have enough water to filter). Hot weather also increases the risk of side effects of treatment drugs such as kidney failure, increased creatinine in the blood. In addition, the hot sun also reduces the circulating volume in the body, causing the blood to condense to form thrombus, causing blood vessel blockage.

These side effects are really dangerous. Therefore, to protect themselves in the hot season, in addition to taking regular medication as directed by the doctor, people with heart failure need to avoid dehydration by limiting going out in the sun when the sun is hot. Should drink a lot of water, drink continuously throughout the day, do not let the situation when you feel thirsty to drink.

Coronary artery disease

Coronary artery disease is the most common form of cardiovascular disease and the leading cause of death in many countries around the world.

The coronary artery system is responsible for supplying blood to the heart muscle. Coronary artery disease is a condition in which the formation of atherosclerotic plaques causes the arteries to narrow, reducing the blood's ability to circulate, so they cannot supply enough oxygen and nutrients to the body. The plaque grows larger over time, the blood flow and oxygen supply to the heart therefore decreases. In the hot summer weather, the circulatory volume decreases, the blood is condensed, so when the artery is narrowed due to atherosclerosis, it is more difficult to circulate, easily leading to arterial occlusion. Depending on the volume of the blocked artery, the consequences will be different, the most dangerous is that it can lead to death.

Therefore, just like people with heart failure, people with coronary artery disease need to know how to protect themselves. In addition to the need to follow the doctor's treatment regimen, the patient should also limit going out when the temperature is too high, drink lots of water, eat a lot of fruit and limit spicy foods. Only in this way can we help reduce the risk of diseases in the summer.

Complications from high blood pressure

The heat is really dangerous for people with high blood pressure. High temperature causes heart rate to increase rapidly and blood pressure to increase, reaching a certain threshold will lead to cerebrovascular accident.

To limit complications caused by high blood pressure, patients need to take antihypertensive drugs every day. For the average person, the heat can also cause a temporary increase in blood pressure. When seeing a person showing signs such as headache, dizziness, hot flashes, people should immediately think of high blood pressure to quickly take the patient to the nearest medical facility.

In the summer, people with cardiovascular disease face many risks. That does not mean that other seasons of the year sick people can be negligent, subjective to the disease. With that said, complications of cardiovascular disease can happen at any time. To prevent complications, patients need to regularly visit medical facilities, have a lifestyle suitable for themselves.

About exercise, every day should practice regularly with moderate exercise or walk for about 30 minutes. This way helps the elderly stabilize blood pressure, reduce excess fat, and improve respiratory and circulatory function. In terms of nutrition, you should create a balanced eating habit, not only eat what you like but should eat what you need. Should increase green vegetables and fiber and limit tolerance of carbohydrates and animal fats as well as alcohol and stimulants.
