Hello and welcome to the zero to finals podcast. My name is Tom and in this episode I'm going to be

talking to you about core pulmonary and you can follow along with written notes on this topic

at zero to finals.com slash core pulmonary or in the cardiology section of the zero to finals medicine book.

So let's get straight into it.

Core pulmonary is right-sided heart failure caused by respiratory disease.

The increased pressure and resistance in the pulmonary arteries,

or pulmonary hypertension,

results in the right ventricle being unable to effectively

pump blood out of the ventricle and into the pulmonary arteries.

This leads to back pressure of blood in the right atrium, the vena cava and the systemic

venous system.

There's a few respiratory causes of core pulmonary. COPD is the most common cause. It can also

be caused by pulmonary embolism, interstitial lung disease, cystic fibrosis and primary pulmonary

hypertension. So how does it present? Often patients with early core pulmonary are asymptomatic.

The main presenting complaint is shortness of breath. Unfortunately, shortness of breath is

also caused by the chronic lung disease that causes core pulmonary. Patients may also

present with peripheral edema, increased breathlessness on exertion, syncope,

which is dizziness or fainting, or chest pain.

If you want to examine the patient for signs of core pulmonary, you need to look for hypoxia,

cyanosis, a raised jugular venous pressure or JVP due to the backlog of blood into the jugular veins,

peripheral edema, a third heart sound, murmurs, for example, a pancystolic murmur which would be heard in tricusped regurgitation,

and hepatomegaly which can occur due to the back pressure
