Common symptoms include swelling and trouble breathing, particularly when ...Read more

When was CHF found?

Remote in history: Long long ago patients were noted to develop swelling and shortness of breath. It was called "hydrops" and was treated with mercurial diuretics in the past before they were found to be toxic due to murcury content giving way to the new diuretics like acetazolamide, thiazides, and loop diuretics.

How can CHF be treated?

Multiple ways: Treatment can focus on 1) improving symptoms (using medications such as diuretics) or 2) treating the underlying problem (such as surgically repairing a valve) or 3) improving the function of the heart (such as a biventricular pacemaker). Factors that aggravate heart failure such as anemia or hyperthyroidism can be corrected.

What factors contribute to chf?

What factors contribute to chf?

Weakness of heart.: CHF is primarily caused by an issue in the heart that prevents it from being able to supply your body with the oxygen it needs. This can be caused by weakness of the heart muscle, insufficiency of a valve in the heart or a rhythm disturbance that disrupts the forward flow of blood from the heart.

Have advances in management affected CHF survival?

Yes: Survival as a measure by itself and event-free, meaningful survival as a whole have improved through research and evidence-based practice of cardiology. Over the past 10 years or so, our better understanding of the disease, better medication regimen, and device therapy have made patient's survival longer and their quality of life better.

How is CHF fatal?

How is CHF fatal?

Breathing trouble.: CHF by itself can be fatal by causing the lungs to fill with fluid in spaces that are normally occupied by air. Exchange of oxygen and carbon dioxide is impaired and vital organs are not properly supplied with oxygen, and they start to fail.

Can stress contribute to chf?

Can stress contribute to chf?

Yes: Stress, particularly long standing stress can cause pertubations to our hormonal axis. This in turn has been shown to impact the inflammatory system. Elevated inflammatory mediators and other indicators of an out of balance inflammatory system are often seen in patients with congestive heart failure (chf). Anything that can reduce stress, can be seen as a positive cardiac mediator.

What is too much exercise for chf?

CHF exercise: We don't prescribe exercise for CHF patients until the CHF is controlled. When we feel control is reached, the patient is started on a low level exercise program tailored to their specific situation. We progress slowly with increases in the work load only very gradually. The patient will feel 'too much' by the symptoms provoked. We try to not get to the point where the patient feels symptoms.

What are signs and symptoms of chf?

Breathing problems: Shortness of breath with only mild exertion associated with leg swelling are the first symtoms of chf. Then it gets worse if not treated. The patient may not be able to sleep flat and wakes up to sit up to breath better. Chest xr and blood tests and heart ultrasound confirm the diagnosis.
