"The term "heart failure" makes it sound like the heart is no longer working at all and there's nothing that can be done. Actually, heart failure means that the heart isn't pumping as well as it should be. Congestive heart failure is a type of heart failure which requires seeking timely medical attention, although sometimes the two terms are used interchangeably."

Bu şekilde açıklanmış burada. Yetmezliği ifade etmek için ben bunu tercih ederdim. http://www.heart.org/HEARTORG/Conditions/HeartFailure/AboutH...


Wikipedia'da şu şekilde:

Heart failure (HF), often referred to as congestive heart failure (CHF), is when the heart is unable to pump sufficiently to maintain blood flow to meet the body's....

Anladığım kadarıyla yetmezlik ve kardiyak disfonksiyon birbirinden farklı. Cardiac dysfunction şu şekilde açıklanmış bir sitede:

"Cardiac dysfunction is defined as an alteration in the relationship between preload (often defined by left ventricular filling pressure) and stroke volume"

Kardiyak disfonksiyona sekonder kalp yetmezliği oluşabiliyor anladığım kadarıyla ama temelinde iki ayrı koşul gibi görünüyor bana (tabi bu işin uzmanı değilim).

Aşağıdaki kaynakta tam da bu anlatılıyor:

Longitudinal data demonstrating that asymptomatic cardiac dysfunction precedes overt HF are scarce, and the contribution of non-cardiac dysfunction to HF progression is unclear. We hypothesized that subclinical cardiac and non-cardiac organ dysfunction would accelerate the manifestation of HF.

"Current HF guidelines1, 2 emphasize the importance of asymptomatic cardiac dysfunction as a preceding stage in the progression to clinically overt HF."
