Heart Failure – Part 2:Clinical Manifestations and Diagnosis Flashcards
3 major symptoms of Cardiac Failure
↓ Cardiac output
↑ Pulmonary venous pressure (Left-sided)
↑ Central venous pressure (Right-sided)
↑ Central venous pressure (Right-sided) causes
edema
- symptoms of Cardiac Failure
↑ Pulmonary venous pressure (Left-sided) causes
breathlessness
- symptoms of Cardiac Failure
↓ Cardiac output causes
Symptoms of decreased organ perfusion
- symptoms of Cardiac Failure
Symptoms of low flow
↓ cerebral perfusion
↓ muscle perfusion
↓ gut perfusion
↓ kidney perfusion
↓ cerebral perfusion (low flow) causes
Sleepiness, confusion
↓ muscle perfusion (low flow) causes
Fatigue, weakness
↓ gut perfusion (low flow) causes
Anorexia, Wasting (cachexia)
↓ kidney perfusion (low flow) causes
Reduced urine output
Progressive renal dysfunction
Symptoms of ↑ left-sided pressure
↑ Pulmonary venous pressure=
Breathlessness (dyspnea) Dyspnea on exertion Orthopnea Paroxysmal nocturnal dyspnea Acute pulmonary edema
Orthopnea or orthopnoea is shortness of breath (dyspnea) which occurs when _______
lying flat, immediate
Delayed SOB, waking patients from sleep
Classically patient gets out of bed and ambulates to relieve symptoms
Relates to mobilization of edema from tissue through lymphatics back into blood stream
Paroxysmal nocturnal dyspnea (PND)
Symptoms of ↑ right-sided pressure
↑ Central venous pressure (RV failure)= Peripheral swelling / dependent edema Ascites Hepatic congestion Intestinal congestion (protein-losing enteropathy)
Precipitating factors producing acute or worsening symptoms
**Increased circulating volume (preload)= Sodium load in diet
Increased pressure (afterload)
Worsened contractility (inotropy)
Arrhythmia (rate)
Increased metabolic demands
**Non-adherence with HF medications
Paroxysmal nocturnal dyspnea (PND)
Delayed SOB, waking patients from sleep
Classically patient gets out of bed and ambulates to relieve symptoms
Relates to mobilization of edema from tissue through lymphatics back into blood stream
