While the term “heart failure” (also known as congestive heart failure) may sound like the heart has stopped working, that isn’t actually the case. It still pumps, just inefficiently. As a result, there’s a reduction in blood flow to the body and a backup (congestion) of fluid into the lungs, liver, abdomen, and lower extremities. While there’s no cure for heart failure, medication and healthy lifestyle changes can help manage the condition and allow people to maintain a good quality of life.
Enlarging the Heart Chamber This is the body’s attempt to get the heart to contract more strongly, in order to pump more blood. Initially, it may help the heart function more efficiently, but ultimately it causes the heart to not pump as effectively and causes fluid retention, leading to congestion in the lungs.Developing More Heart Muscle Mass The contracting cells in the heart get bigger, which initially lets the heart pump more strongly.Increasing Heart Rate This causes the heart to pump faster and increase its output.Increasing Fluid and Salt Retention and Tightening Some Blood Vessels This helps maintain the heart’s normal output.
These compensations may mask heart failure temporarily, but eventually heart failure gets worse, and people start to experience symptoms.

The researchers also say that because many women are discharged from hospital care just a couple of days after giving birth and aren’t given a follow-up appointment until about six weeks later, the way doctors regard women who might be at risk of heart failure needs to change. They call for comprehensive postpartum discharge health education, with emphasis on signs and symptoms to look for and when or where to seek immediate care. Your doctor will take a full medical history and perform a physical examination. Using a stethoscope, a physician can listen for signs of congestion in your lungs and may also be able to pick up abnormalities in the sound of your heartbeat that can suggest heart failure.
Prognosis of Congestive Heart Failure
Your life expectancy after heart failure depends on the cause of your condition, as well as other factors, including age.
Medication Options
Angiotensin-converting enzyme (ACE) inhibitors to decrease blood pressure, helping blood flow through the body more easily and decreasing the workload of the heart. Also, ACE inhibitors can help limit bad changes to the heart in response to an injury (for example, after a heart attack).Angiotensin 2 receptor blockers have many of the same benefits as ACE inhibitors and are often prescribed as an alternative for patients who cannot tolerate ACE inhibitors.Beta-blockers work by slowing down the heart rate and decreasing the effects of adrenaline on the heart. This in turn lowers blood pressure, so that the heart has to do less work. These medications, similar to ACE inhibitors and angiotensin 2 receptor blockers, limit and may even reverse some of the damage to the heart caused by heart failure.Diuretics, often called water pills, rid the body of excess fluids and sodium through urination. This helps relieve the heart’s workload.Aldosterone antagonists are a type of diuretic that, unlike other diuretics, do not deplete potassium. They also have additional properties that can help a person with severe heart failure live longer.Digitalis can help the heart strengthen its contractions when its pumping function has been weakened. The drug can help reduce symptoms of heart failure.Positive inotropes are reserved for people with the most severe stage of heart failure and are generally used in the hospital. These are intravenous drugs that maintain blood pressure and improve heart function.Hydralazine and isosorbide dinitrate can help relax blood vessels and is typically used as a supplemental drug to treat heart failure, particularly if ACE inhibitors or beta-blockers aren’t working.Vericiguat is a newer once-a-day oral medication used to reduce the risk of death from heart failure.Sodium-glucose cotransporter-2 inhibitors (SGLT2 inhibitors) are recommended as an additional therapy for people with heart failure and reduced ejection fraction, meaning the heart doesn’t pump out enough blood with each heartbeat.
Surgery for Heart Failure
Coronary bypass surgery treats blocked arteries by removing healthy arteries from other parts of the body and using them to reroute blood around clogged arteries. This improves blood flow to the heart. If severely blocked arteries are a contributing factor to your heart failure, your physician may suggest bypass surgery.Heart valve replacement modifies a faulty heart valve to eliminate backward blood flow. A surgeon will either repair the valve, if possible, or replace it with an artificial valve.Ventricular assist devices are mechanical pumps implanted in the abdomen or chest and attached to the weakened heart. The devices help pump blood from the lower heart chamber to the rest of your body.Implantable cardioverter-defibrillators are implanted beneath the skin in the chest with wires leading through the veins and into the heart. These devices monitor heart rhythm and will shock the heart back into normal rhythm if it develops a life-threatening arrhythmia. They can also act as pacemakers, speeding up the heart if it begins beating too slowly.Cardiac resynchronization therapy, also known as biventricular pacing, sends electrical pulses to the heart’s lower chambers to help them pump more efficiently.Heart transplant is an option in the most serious heart failure cases, when medication or surgery do not help. The procedure involves removing the damaged heart and replacing it with a healthy one from an organ donor.
Prevention of Congestive Heart Failure
The best way to prevent heart failure is to control your risk factors. The good news is that you can reduce or eliminate many of the risk factors that lead to heart disease, such as high blood pressure. Lifestyle changes and adhering to any medication your doctor prescribes can go a long way in preventing heart failure.
Quitting smokingEating a healthy dietGetting enough physical activityMaintaining a healthy weightControlling high blood pressure and diabetesReducing stress
The condition often occurs as the result of congestive heart failure. It can also be the result of medication, pregnancy, or another underlying condition, such as kidney disease or cirrhosis of the liver. Signs that you have edema include:
Swelling or puffiness of the tissue directly under the skin, especially in the legs or armsArms or legs start to feel full or heavyShiny or stretched skinSkin that retains pits, or dimples, after being pressed for several secondsClothing or jewelry starts to feel tight and uncomfortableSkin near the swelling feels tight or warmIt becomes more difficult to move the joints that are affectedIncreased abdominal size
Sleep Apnea and Heart Failure
People who have sleep apnea experience interruptions in breathing that can last 10 seconds or more and occur repeatedly throughout the night, as many as 30 times or more in the span of an hour. This chronic disruption of the normal sleep cycle can leave individuals with the condition feeling exhausted and sleepy during the day, and it will put them at an increased risk of health problems associated with inadequate sleep, including irritability, problems with memory or concentration, anxiety, and depression. Sleep apnea is commonly found in people with heart failure. This is the leading heart disease organization in the United States. Their online resources on heart failure offer clear explanations of the condition for both patients and family members, as well as links to many other tools and resources. You can also get information through your local AHA office and learn about volunteer opportunities. Heart Failure Society of America The website for this society, which is made up of researchers, clinicians, and trainees, discusses new treatments and research results in their field. The site also provides valuable information for people living with a heart condition. You can learn facts about heart failure, as well as find out about apps and podcasts to help you better manage the condition. CardioSmart The American College of Cardiology’s website is full of resources for patient education and empowerment. Check out basics about heart conditions, drugs and treatments, and news and events. By creating a profile, you can sign up to receive personalized newsletters and discussion guides to bring with you to your next doctor appointment.
