Answer 1

Right sided CHF

1. Causes of right sided CHF include

Coronory artery disease, where the devoloped plaque in the right coronory artery will interact wiith to blood flow towards and away from the artery leading to heart failure.

Blood pressure, The heart needs to pump hard if there is high blood pressure in the patient. Overtime the heart muscle become thickened and weakens due to the pumping pressure.

Damaged heart valve, The valves keep the blood flow in the right direction of the heart, if they are damaged it become harder to pump the blood leading to right sided CHF.

Arrythmia, if the heart beat become irregular, eveen beat slower can lead to pumping insufficient blood throghout the body.

Patients with congenetal heart disease in the right coronory artery at also at high risk.

Problems in the lungs can cause right side of the heart to enlarge which can lead to pumping difficulties.

2. Right sided CHF disese process;

Right sided CHF occurs when the right ventricle of the human heart has the difficulty to pump the blood to the lungs due to various factors mentioned above. Difficulty in blood pumping can cause the retention of the pumped blood in the blood vessels or back up of the bloods, this cause fluid retention in lower extremeties, abdomen and in other organs also. The right sided and left sided CHF can occur simultaneously in a patient at a time.

3. Sign and symptoms;

Oedema, The fluid retention due to the back up of blood in the vessels lead to oedema in various body parts including vital organs. Neck veins can even swell.

The extremeties of feet, legs and angles become swellen. The abdomen get distended if they back up into the stomach or liver.Due to the oedema there will be a frequent feel of urination espacially at night. The weight gain in patient is possible due to oedema.

As the persistance of the condition occurs various other symptoms can also seen. The pulse of the patient sometimes become faster or feel nil. The patient become difficult to breath if the heart failure get worsens. The skin become cold and sweaty.

4. Body compensation for the effect caused by the disease process.;

As the heart did not pump enough blood in the body, the body didnt get get enough oxygen, so it believes that there is no required fluid in vessels, leading the the body hormone and nervous system will make up it by increasing blood pressure. This is done by retaining sodium salt and water in the body. The hormones like renin angiotensin aldosterone is released for the compensation which make the blood vessel to constrict. As the blood pressure increases the heart rate also get increased in attempt to overcome the poor blood circulation. The heart will compensate the condition by pumping more blood on each of the beat, that is by increasing the stroke volume.
