Summary
Congestive heart failure (CHF) affects many, often progressing rapidly. This study analyzed 6428 patients over 6 years, finding chronic ischemic disease and hypertension as primary causes, with NYHA functional classes II and III being most common.
Area of Science:
- Cardiology
- Public Health
Background:
- Congestive heart failure (CHF) is a prevalent and serious condition with a poor long-term prognosis.
- CHF exhibits a tendency for rapid progression, necessitating a deeper understanding of its contributing factors and patient outcomes.
Purpose of the Study:
- To conduct a retrospective analysis of congestive heart failure (CHF) patients.
- To determine the New York Heart Association (NYHA) functional class and type of CHF.
- To identify the primary diseases leading to heart decompensation and causes of mortality in CHF patients.
Main Methods:
- Retrospective investigation of 6428 patients over a 6-year period.
- Analysis of patient data to determine CHF prevalence, NYHA functional class, and associated comorbidities.
- Examination of mortality data and survival duration post-symptom manifestation.
Main Results:
- 1095 patients (17.03%) had congestive heart failure (CHF), predominantly in NYHA functional classes II and III.
- CHF frequency significantly increased in the 61-70 age decade.
- Key underlying diseases included chronic ischemic heart disease, arterial hypertension, COPD with chronic cor pulmonale, and valve diseases.
Conclusions:
- Chronic ischemic heart disease and arterial hypertension are major contributors to CHF.
- CHF patients in functional classes II and III are common, with increased incidence in older age groups.
- The average age of deceased CHF patients was 67.8 years, with a mean survival of 13.2 years after symptom onset.

01:26Imbalances in Cardiac Output
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send blood...

01:27Heart Failure I: Introduction
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...
01:29Heart Failure II: Pathophysiology
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
01:26Heart Failure III: Clinical Manifestations
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

01:30Cardiomyopathy II: Dilated Cardiomyopathy
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
