Differential Diagnosis for Hypertension, Tachycardia, Diaphoresis, and Chest Tightness

Single Most Likely Diagnosis

  • Anxiety or Panic Attack: The symptoms of hypertension, tachycardia, diaphoresis, and chest tightness without chest pain are commonly seen in anxiety or panic attacks. The absence of chest pain reduces the likelihood of a cardiac cause, making this a plausible explanation.

Other Likely Diagnoses

  • Hyperventilation Syndrome: Often presents with similar symptoms due to rapid breathing, leading to respiratory alkalosis, which can cause chest tightness and tachycardia.
  • Dehydration or Electrolyte Imbalance: Can lead to tachycardia and hypertension due to decreased intravascular volume or electrolyte disturbances affecting cardiac function.
  • Thyroid Storm: Although less common, it can present with hypertension, tachycardia, and diaphoresis, along with other symptoms like fever and agitation.

Do Not Miss Diagnoses

  • Myocardial Infarction (MI) or Acute Coronary Syndrome (ACS): Although chest pain is a classic symptom, some patients, especially women, diabetics, or the elderly, may present with atypical symptoms such as chest tightness or no chest pain at all. Missing an MI or ACS can be fatal.
  • Pulmonary Embolism (PE): Can present with tachycardia, diaphoresis, and chest tightness, especially if the embolism is large and causes significant pulmonary hypertension.
  • Aortic Dissection: A life-threatening condition that may present with hypertension and chest pain or tightness, often described as tearing or ripping in nature.
  • Pheochromocytoma: A rare tumor of the adrenal gland that can cause episodic hypertension, tachycardia, diaphoresis, and chest tightness due to excessive catecholamine release.

Rare Diagnoses

  • Catecholamine Crisis due to Other Causes: Such as a paraganglioma or certain drugs and substances that can mimic pheochromocytoma symptoms.
  • Cardiac Tamponade: Although typically presents with hypotension, in the early stages or with a small effusion, it might cause chest tightness and tachycardia.
  • Hypertensive Emergency due to Other Causes: Such as eclampsia, malignant hypertension, or renovascular disease, which can present with severe hypertension and symptoms like chest tightness.
