Heart failure is a condition in which the heart cannot supply as much blood as the body needs. With appropriate treatment and management, it is possible to maintain daily life, but if left untreated, symptoms such as shortness of breath and swelling can worsen.

Heat Waves and Heart Health

#heat wave, #sudden cardiac death, #heat stroke, #heat-related illness, #heart attack, #angina, #cardiac arrest, #arrhythmia, #hydration, #summer health, #dizziness, #feeling faint, #unsteadiness, #vision going dark, #fainting, #loss of consciousness, #syncope, #breath holding, #difficulty breathing, #shortness of breath, #choking sensation

Extreme heat raises the risk of angina, heart attack, and cardiac arrest by increasing heart rate, promoting blood clotting, and placing added strain on the heart. Older adults age 65 and older, people with cardiovascular disease, and those with chronic conditions such as high blood pressure or diabetes need to be especially careful. On days when a heat wave warning is issued, please stay active indoors for safety.

Hypertension (High Blood Pressure)

#hypertension, #blood pressure, #blood pressure medication, #sodium, #arteriosclerosis, #antihypertensive drugs, #essential hypertension, #headache, #a splitting headache, #migraine, #back-of-head pain

Hypertension is a condition in which blood pressure, the force exerted on the walls of the blood vessels when the heart pumps out blood, stays persistently high; it is classified as a systolic blood pressure of 140 mmHg or higher or a diastolic blood pressure of 90 mmHg or higher. Hypertension often causes no symptoms, so it is called the "silent killer." If left untreated, it can lead to serious complications such as stroke, heart disease, and kidney disease, so evaluation by a medical specialist and steady management are needed.
