A heart murmur is what doctors call the rushing sound of blood through the heart. Though usually asymptomatic and largely harmless, murmurs are usually caused by some fault in the valves of the heart, which can cause leaking or inefficient blood flow. Alternately, a murmur could be the result of the heart beating more rapidly than normal, which causes an excess of blood to be handled by the muscle. Most people with murmurs may not even know they have one. However, here are five signs that your heart is in serious trouble to look out for.
5. Blue Lips Or Fingertips
Blue lips or fingertips are a sign of cyanosis, which is an indication of a lack of oxygen in the blood or poor blood circulation. If an individual has a heart murmur and is exhibiting signs of cyanosis, it means that the heart is not getting enough blood to the body’s vital systems. If left untreated for more than three to five minutes, severe hypoxia can occur, which can cause permanent brain damage or even death.
