Heart Failure: Symptoms, Causes, and Types

 Heart Failure

Heart failure is a medical condition in which the heart stops pumping enough blood to the body. It is an emergency situation in which immediate management and care is required. The patient is having heart failure if they experience shortness of breath, chest pain, and edema in the legs. Heart failure has different types, and each type has a unique way of managing the condition. 

What is heart failure?

When the heart is unable to pump enough blood, it results in a condition known as heart failure. This decreased blood supply can lead to impaired functioning of the body. Despite a heart attack, the heart continues to function, but its pumping action becomes compromised, which affects its ability to provide sufficient output for the proper functioning of the body.

Heart failure also causes the accumulation of blood in the legs and abdomen, which is also known as a pooling of the blood. Sometimes, blood also pools in the lungs which further complicates the condition of the patient.

What are the causes of Heart Failure?

Heart failure can have different causes. Most patients with two or more risk factors are more likely to get heart failure. It is also very important to know about the cause of heart failure due to the different management and treatment techniques according to the root cause. Some of the causes of heart failure are as follows

Causes of Left-Sided Heart Failure Systolic Heart Failure

• Coronary artery disease
• Hypertension
• Heart Attack
• Cardiomyopathy 
• Viral infection
• Medication effect
• Diastolic Heart Failure 
• Hypertension
• Tightness of aorta
• Hypertrophic cardiomyopathy
• Restrictive cardiomyopathy

Causes of Right-Sided Heart Failure Left-sided heart failure

• Chronic lung diseases
• Pulmonary embolism
• Pulmonary hypertension
• Congenital heart defects
• Right ventricular infarction

What are the symptoms of Heart Failure

The patient who is having a heart failure might show the following symptoms

• Shortness of breath 
• Chest pain
• Edema or swelling in feet, ankles, legs, or abdomen
• Irregular and loud heartbeats
• Difficulty breathing when lying flat
• Sudden shortness of breath at night
• Persistent cough or wheezing
• Rapid weight gain
• Abdominal swelling due to fluid accumulation
• Fatigue or weakness
• Reduced exercise tolerance
• Dizziness or lightheadedness
• Nausea
• Loss of appetite
• Difficulty concentrating or decreased alertness

What are some of the risk factors of Heart Failure?

Heart failure is associated with some risk factors. These risk factors can be modified to decrease the incidence of the heart. Some of the risk factors are described as follows
Age: Patients with age more than 60 years have a high risk of heart failure.
Hypertension: Hypertension is a condition in which blood pressure becomes high. High blood pressure increases the risk of heart failure.
Diabetes: High blood sugar level is associated with heart failure.
Sleep apnea: Difficulty in breathing during sleep is also associated with the risk of heart failure.
Obesity: Obese persons are at high risk of cardiac diseases, including heart failure.
Gender: The male population is more prone to develop heart diseases, including heart failure, as compared to females.
Family History: A positive family history of heart disease also increases the risk of heart failure in close family members.
Chronic kidney disease: Kidney disease also affects heart function, which increases the risk of heart failure.
Cardiac diseases: Cardiomyopathy, coronary artery disease, and heart viral infections are some of the cardiac diseases that can also cause heart failure.
Poor lifestyle: Limited activity and a poor diet with high fats can also lead to the development of heart failure. 
Smoking: Smoking can cause injury to the blood vessels, which can lead to various heart diseases like heart failure.
Stress: High stress is also associated with heart failure.
Excessive alcohol consumption: Patients who consume excessive alcohol can develop heart diseases.

What are the types of Heart Failure?

Heart failure is classified into two major types: right-sided and left-sided heart failure. Both types of heart failure lead to symptoms like retention of fluid, shortness of breath, etc.

Left-Sided Heart Failure
Left-sided heart failure occurs when the left ventricle, situated at the bottom left of the heart, does not effectively pump out blood. It prevents the body from receiving blood and performing its functions. Left-sided heart failure is further has two sub-types

Systolic Heart Failure: It is a type of left-sided heart failure in which the heart muscle does not work properly and leads to a weakened left ventricle that cannot pump blood throughout the body. This results in blood pooling in the lungs and limbs. Systolic heart failure is more common in men.
Diastolic Heart Failure: This occurs when the heart muscle becomes stiff and affects the heart's ability to relax. It leads to the prevention of the heart from filling with enough blood. Diastolic heart failure is more common in women.

Right-Sided Heart Failure
The right ventricle, situated at the bottom right side of the heart, is responsible for pumping blood to the lungs for oxygen. Left-sided heart failure often leads to right-sided heart failure, as the blood accumulation in the lungs forces the right ventricle to work harder. This increased workload can put extra stress on the right side of the heart, leading to its failure.

How to manage Heart Failure?

Heart failure treatment involves treatment with medications, surgery, and lifestyle modification. Lifestyle modification is necessary even after surgical treatment for the prevention of the recurrence of the disease. Let’s discuss heart failure treatment
Management with Medications

• ACE Inhibitors
• Beta-Blockers
• Diuretics
• Aldosterone Antagonists
• Angiotensin II Receptor Blockers 
• Angiotensin Receptor-Neprilysin Inhibitors
• Digoxin
• Vasodilators
• Ivabradine
• Hydralazine and Nitrates

Management with Surgical Interventions

• Implantable Cardioverter-Defibrillator 
• Cardiac Resynchronization Therapy 
• Left Ventricular Assist Device 
• Pacemaker
• Heart Valve Repair or Replacement
• Coronary Artery Bypass Grafting
• Heart Transplant

Management with Lifestyle modification:

Balanced diet

• Fluid Restriction
• Regular Physical Activity
• Weight Management
• Smoking Cessation
• Limiting Alcohol Intake

How can we prevent Heart Failure

Heart failure can be prevented by modifying risk factors. Some modifiable risk factors may include weight management, lifestyle modification, etc. So, one can prevent heart failure by balancing diet, managing stress and weight, activity modifications, and limiting smoking and alcohol consumption.
Heart failure occurs in people who are exposed to risk factors. It can occur due to many problems like heart disease, stress, kidney disease, and hypertension. Heart failure can be managed with different types of medications, surgical interventions, and lifestyle modification.
