Heart failure is caused by heart conditions such as abnormal heart rhythms and coronary heart disease. Read on as Professor Carolyn Lam, Senior Consultant, Department of Cardiology at National Heart Centre Singapore explains more in detail.
Heart failure means that your heart functions below par and is thus unable to pump enough blood for the body’s needs. It is a serious condition since all the organs, tissues, and cells in your body require proper blood flow to accomplish their tasks. Heart failure can affect one or both sides of the heart.
“In heart failure, because the heart isn’t performing its job well, fluid builds up in the lungs and patients feel breathless. This can be so severe that patients cannot carry out their usual activities of daily living, or feels like he or she is drowning,” explains
