Study Notes
- Study notes on the presentation, diagnosis, red flags, treatment, patient education, referrals, and follow-up for Congestive Heart Failure (CHF) Exacerbation, Pulmonary Embolism (PE), Supraventricular Tachycardia (SVT), Cardiac Tamponade, and Hypertensive Crisis.
Congestive Heart Failure (CHF) Exacerbation
- CHF exacerbation involves the worsening of heart failure symptoms.
- Symptoms include shortness of breath, edema, and fatigue.
- Red flags: severe dyspnea, chest pain, altered mental status.
- Treatment focuses on reducing fluid overload and improving cardiac function, often with diuretics and vasodilators.
- Patient education covers medication adherence, diet, and recognizing worsening symptoms.
- Refer to cardiology; follow up to monitor symptoms and adjust treatment.
Pulmonary Embolism (PE)
- PE occurs when a blood clot blocks an artery in the lungs.
- Presentation: sudden shortness of breath, chest pain, and cough.
- Red flags include: signs of shock, massive PE.
- Diagnosis involves imaging such as CT angiography.
- Treatment includes anticoagulation and, in severe cases, thrombolysis or embolectomy.
- Education focuses on anticoagulation management and prevention.
- Refer to pulmonology or cardiology; follow up to monitor for complications and recurrence.
Supraventricular Tachycardia (SVT)
- SVT is a rapid heart rate originating above the ventricles.
- Presentation: palpitations, dizziness, and sometimes chest discomfort.
- Red flags: hemodynamic instability.
- Treatment involves vagal maneuvers, adenosine, or cardioversion if unstable.
- Education includes avoidance of triggers and understanding treatment options.
- Refer to cardiology if recurrent; follow up to assess arrhythmia control.
Cardiac Tamponade
- Cardiac tamponade is the compression of the heart due to fluid accumulation in the pericardial sac.
- Presentation: Beck's triad (hypotension, muffled heart sounds, JVD), shortness of breath.
- Red flags: rapid deterioration.
- Diagnosis is often clinical with echocardiography confirmation.
- Treatment involves pericardiocentesis or surgical drainage.
- Refer urgently to cardiology or cardiothoracic surgery; close follow up to monitor for recurrence.
Hypertensive Crisis
- Hypertensive crisis is a severe elevation in blood pressure that can cause organ damage.
- Presentation: severe headache, chest pain, shortness of breath, neurologic symptoms.
- Red flags: end-organ damage.
- Treatment involves controlled reduction of blood pressure with IV medications.
- Education focuses on medication adherence and lifestyle modifications.
- Refer to nephrology or cardiology; close follow up to monitor blood pressure and organ function.
