We discuss the major underlying mechanisms, including hypovolemia, distributive shock, cardiogenic causes, and obstructive physiology, along with common risk factors such as dehydration, hemorrhage, sepsis, medications, endocrine disorders, and cardiac disease. The episode highlights classic signs and symptoms including dizziness, syncope, weakness, altered mental status, tachycardia, and signs of shock, emphasizing the importance of identifying the underlying cause rather than treating the blood pressure value alone. We also review key components of the diagnostic evaluation, including orthostatic vitals, laboratory studies, EKG, and bedside assessment of perfusion, as well as initial management with fluid resuscitation, vasopressors when indicated, and rapid treatment of the underlying etiology.

Cardiovascular - Hypertension Emergency

In this episode, we review hypertensive emergency, a life-threatening condition defined by severely elevated blood pressure accompanied by acute end-organ damage. We discuss the underlying pathophysiology of vascular endothelial injury and impaired autoregulation, along with common risk factors such as chronic uncontrolled hypertension, medication nonadherence, kidney disease, stimulant use, and endocrine disorders. The episode highlights classic clinical presentations including neurologic deficits, chest pain, pulmonary edema, acute kidney injury, and retinal changes, emphasizing the importance of identifying organ dysfunction rather than focusing on the blood pressure number alone. We also cover diagnostic evaluation, including laboratory testing, EKG, imaging, and fundoscopy, as well as evidence-based treatment with carefully titrated IV antihypertensive therapy to avoid overly rapid blood pressure reduction.

Cardiovascular - Giant Cell Arteritis

In this episode, we review giant cell arteritis (GCA), an autoimmune large-vessel vasculitis that most commonly affects the temporal arteries and can lead to devastating ischemic complications if not recognized early. We discuss the underlying inflammatory pathophysiology, major risk factors including advanced age and polymyalgia rheumatica, and the hallmark presentation of temporal headache, jaw claudication, scalp tenderness, and transient vision loss. The episode also covers key diagnostic findings such as elevated ESR and CRP, the classic "halo sign" on Doppler ultrasound, and why temporal artery biopsy remains the gold standard for diagnosis. Treatment focuses on the urgent initiation of high-dose glucocorticoids to prevent permanent vision loss and other vascular complications. References 1.

Cardiovascular - Atrial Flutter

In this episode, we review atrial flutter, a supraventricular tachyarrhythmia caused by a reentrant electrical circuit within the atria that produces the classic "sawtooth" flutter waves on EKG. We discuss the underlying pathophysiology, major risk factors including heart failure, COPD, coronary artery disease, hypertension, hyperthyroidism, and obstructive sleep apnea, and the typical presentation of palpitations, dyspnea, fatigue, and chest pain. Diagnostic evaluation focuses on recognizing the characteristic 2:1 AV conduction pattern with atrial rates near 300 bpm and ventricular rates around 150 bpm. We also cover acute management with rate control, rhythm control, and cardioversion, as well as long-term treatment strategies including catheter ablation and anticoagulation guided by the CHA₂DS₂-VASc score.
