Symptom # 4: Racy heart beat
Another extremely common red flag that indicates that you have heart failure, and it occurs when your body realizes that the heart can no longer effectively pump blood to the organs and it attempts to delegate this task to other minor organs and make up for the deficiency of blood.
This mechanism can work in several ways. For instance, the body can enlarge your heart to make it stretch and snap, and spring into action once again. Or, the body can make your heart beat faster. Also, it can add up more muscles to the heart in order to give a stronger push. All these body mechanisms cause your heart beat to accelerate and you may feel that your heart is racing.
Symptom # 5: A State of Confusion
Patients often complain of sluggishness, utter confusion, forgetfulness and a state of disorientation. This happens because the body organs and even brain fails to perform its regular duties effectively due to the lack of blood. And this also disturbs the proportionate balance of other elements present inside the blood, for instance, oxygen and sodium. And this imbalance affects the brain very adversely.
Symptom # 6: Nausea
Nausea is one of the most common signs of heart failure. Some patients also tend to feel filled up and they tend to avoid eating. Nausea is often accompanied by a lack of hunger and an inability to eat. And this happens because the digestive system is deprived of an adequate supply of oxygen and blood.
Symptom # 7: Persistent Wheezing and Bouts of Cough
Another strong indicator that proves that your heart is unable to perform its basic duties, and the blood keeps returning to the lungs without being oxygenated and effectively pumped back to the body. It also indicates that your lungs are retaining fluid, and in certain cases, coughing tends to bring out a pink or white colored mucus. If you spot this mucus in your coughs, be sure to report it to your doctor right away.
