(中英字幕EngSub)小心這個病徵，及早發現可拯救生命Beware of this very important sign of serious heart problem

heart failure is commonly seen in the elderly but now younger people should be cautious as well I'll explain later in simple term the blood pumping function is poor in heart failure; by definition if output in every heart beat is less than 40% of normal there is heart failure; blood will pool in the lungs like a clogged drain blood pooling in the lungs will cause difficult breathing shortness of breath is a common symptom in heart failure this is a slow progressive process where early symptoms are minimal poor cardiac output would cause weakness/tiredness many older people attribute these to aging and diagnosis may be delayed there is one symptom which is characteristic of heart failure it is breathlessness at night which may be relieved by sitting up at night to fall asleep so if you have the above symptoms what should you do? you may consult your GP before seeing a cardiologist nowadays a simple blood test can detect heart failure a failing heart distended by blood will secret a substance called BNP if it's level is very high and there are symptoms heart failure is likely a simple electrocardiogram can help in diagnosis as well if it shows a bigger ventricle or strange rhythm it may also indicate heart failure younger people should be pay attention to heart failure symptoms because COVID-19 may cause myocarditis which in some cases may progress to heart failure this may not be a common occurrence but considering the vast number of people infected with COVID some will develop heart failure especially if younger people have reduced exercise tolerance you may think that heart failure is not as dangerous as cancers but in elderly heart failure patients if they require hospitalizations the death rate in the few years ahead can be higher than many cancers so pay attention to symptoms of elderly people in your family thanks for watching and I'll see you in the next one
