Cardiovascular diseases

What is Cardiovascular diseases.

Introduction of Cardiovascular diseases

Cardiovascular diseases is the most common disease in the world Centers for Disease Control and Prevention (CDC). It is recorded that one in four persons has heart disease. William Harvey excellently describes the more deeply parts of the heart, offering an early understanding of the causes of congestive heart failure diseases worldwide. He noticed that heart failure was connected to a dilated ventricle. The heart and its blood arteries make up the cardiovascular system. The circulatory system can encounter various problems, including CAD, congestive heart failure, endocarditis, and an irregular conduction system, which causes other major heart problems. Heart attack is one of the major heart diseases.

Heart Failure Reasons

Heart failure is the most common disease worldwide and is more dangerous. Heart mostly disease due to dust and more tension are the main causes of heart failure. The heart is mostly searched in men. And the new generation is mostly causing this disease due to depression. In this disease, the heart pumping does not work properly and is mostly a pain in the heart. Sudden pain in the heart. It develops when the heart cannot discharge its contents properly to fulfil the body’s needs. Heart failure is a common cause of death in many people because of its severe effect.

The weakening and stiffening of heart tissue starts at this stage due to some conditions, including the narrowing of arteries. Heart failure is also said to be congestive heart failure. Coronary artery blockage happens, which stops the flow of blood, due to which the tissue of the heart muscles starts dying. Our body has a demand for blood which is rich in oxygen that comes from the heart, but due to the malfunction of our heart, the blood does not meet the requirements of our body, so many sign and symptoms appears gradually, which tells us that we are going towards heart failure. The heart is the main organ of the human body, and when the heart is stopped, the human being is no more in life. The whole Blood supply controls the human heart.

 Right-sided heart failure

Right-sided ventricle fails when it cannot generate enough force to push blood through the lungs. It may also be caused by increased vascular resistance in the lungs. When this is increased, the right ventricle has to work more than normal, or weakness of the myocardium, which is caused by myocardial damage which follows ischemia or infarction. When it fails, the compensatory mechanism starts. When the compensation process has reached, its limit and the ventricle can no longer empty adequately. 

The main clinical manifestations depend on which side of the heart is most affected, the right value cava and the right atrium become congested, and this congestion follows back, involving the complete heart. The other organs are affected by this congestion, like the liver, spleen, and kidneys. Typically, ascites and limb oedema follow. Biventricular failure patients had a two years survival rate of 23% against 71% for those with LVF alone, and LVF most frequently causes RVF.

Triggering factors of right-sided heart failure are coronary artery disease, diabetes, heavy alcohol use, obesity, use of cocaine, and high Blood pressure. But the major cause of right-sided heart failure is left ventricular failure via volume and pressure overload.


Some signs and symptoms of right-sided heart failure are coughing, dizziness, hepatomegaly, fatigue, waking at night with shortness of breath, and ascites. Weight gain may be a sign at this stage because if the right side of the heart stops working, it can cause oedema. Some diagnostics are used to detect RHF, like Magnetic Resonance Imaging MRI, which can determine and measure the regurgitant volumes, delayed enhancement, scar load, strain, perfusion, and pulpability of the lungs. RVEF and RV volume measurements may be performed using computed tomography (CT). In my opinion, RVF, RHC, and PAC are very helpful.

The life side of the heart side, it can control the left ventricle and supply the whole body. Failure of the left heart can be caused by numerous factors. Chronic or poorly managed hypertension increases afterload, which raises cardiac effort and can cause left ventricular hypertrophy. The senior population is more prone to heart failure, which is more common. The number of Americans with a heart failure diagnosis is 5.7 million.

Stages of Heart Failure

Stage 1 At this stage, no symptoms appear and no limitations in physical activity.

Stage 2 At this stage, mild symptoms appear and a limitation during physical activity.

Stage 3 At this stage, symptoms that require little effort and severely limit daily activity.

Stage 4 At this stage, even at rest, crippling symptoms are present.

Triggering factors of left-sided heart failure are coronary artery disease, ischemic heart disease, which causes a reduction in the efficiency of the myocardium, a heart attack, or long-term high blood pressure.

Clinical Manifestations 

The sign and symptoms of left-sided heart failure are dyspnea which is called shortness of breath, hemoptysis, pulmonary congestion, and cough. The person having heart failure may look fatigued every time and cannot perform daily life activities effectively. We can see the heart rate through the ECG monitoring and also control the heart rate of the patient. Another heart failure is weight loss in men because the pumping heart does not work properly.


Treatment of left-sided heart failure includes medications, lifestyle changes, surgery, and cardiac resynchronization therapy Medication can address left-sided heart failure symptoms, including fluid buildup, elevated blood pressure, and improved cardiac function as they improve blood flow by opening narrowed blood vessels and slow down the rapid heart rhythm and reduce blood pressure.
