Summary
A rare central distribution of lung opacities in cellular non-specific interstitial pneumonia (c-NSIP) can mimic congestive heart failure. Prompt diagnosis and steroid treatment led to symptom resolution in this case.
Area of Science:
- Pulmonology
- Radiology
- Pathology
Background:
- A 66-year-old female with prior myocardial infarction presented with cough and night sweats.
- Initial chest imaging revealed ground glass opacities with central redistribution, suggesting congestive heart failure.
Observation:
- Symptoms and radiographic findings were unresponsive to diuretic therapy.
- Video-assisted thoracoscopic surgery confirmed cellular non-specific interstitial pneumonia (c-NSIP).
Findings:
- Cellular non-specific interstitial pneumonia (c-NSIP) can present with unusual central radiological distribution.
- Absence of rales was noted due to the limited fibrotic component in c-NSIP.
Implications:
- Highlights the importance of considering c-NSIP in cases with atypical radiological patterns mimicking other conditions.
- Emphasizes the diagnostic challenge and successful steroid treatment for c-NSIP with central lung findings.

Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.

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...

01:27Heart Failure I: Introduction
865
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...

3.5K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
