18 Possible Causes for Narrow Pulse Pressure, Prerenal Azotemia

  • Congestive Heart Failure

    Signs There may be a tachycardia at rest, low systolic blood pressure (BP), a displaced apex (LV dilatation) or RV heave (pulmonary hypertension), a narrow pulse pressure[patient.info]

  • Hypovolemia

    If the difference is less than 25 percent of the systolic blood pressure, the pulse pressure is considered to be narrow.[ems1.com] Class IV hemorrhage (loss of 40%) Symptoms include the following: marked tachycardia, decreased systolic BP, narrowed pulse pressure (or immeasurable diastolic pressure),[emedicine.medscape.com] A narrow pulse pressure in a hypovolemic shock patient indicates a decreasing cardiac output and an increasing peripheral vascular resistance.[ems1.com]

  • Acute Myocardial Infarction

    Ventricular septal rupture (VSR) is a rare but fatal complication of acute myocardial infarction (AMI) with an associated mortality that ranges from 41% to 80%. The treatment consists of supplemental oxygenation, afterload reduction, intraaortic balloon pump, and surgical repair. In selected patients, extracorporeal[…][ncbi.nlm.nih.gov]

  • Dehydration

    The purpose of this study is to present a case report of a child with hyponatremic dehydration diagnosed after CF and to review the cases of 13 patients with CF who had the same initial presentation in our hospital. This report reviewed the clinical records of children diagnosed with CF to ascertain the[…][ncbi.nlm.nih.gov]

  • Addison's Disease

    Patients with type 1 diabetes mellitus (T1DM) have an increased risk of other autoimmune disorders. The combination of Addison's disease with T1DM and/or autoimmune thyroid disease is known as autoimmune polyendocrinopathy type 2 (APS-2). 21-hydroxylase autoantibody (21OHAb) is considered as a valuable marker for[…][ncbi.nlm.nih.gov]

  • Cardiac Tamponade

    pulse pressure and pulsus paradoxus may also be observed. 2 The diagnosis can be rapidly confirmed by bedside ultrasound. 3 In traumatic cardiac tamponade, the treatment[westjem.com] Cardiac tamponade often presents as a cardiogenic obstructive shock with shortness of breath, tachycardia, hypotension with a narrow pulse pressure (but blood pressure may[acls.com] […] with chest pain and respiratory distress. 2 Beck’s triad may be present on exam, as it was in our case: muffled heart sounds, distended jugular veins, and hypotension. 1 A narrow[westjem.com]

  • Hypovolemic Shock

    If the difference is less than 25 percent of the systolic blood pressure, the pulse pressure is considered to be narrow.[ems1.com] However, it is likely that there will be a narrowed pulse pressure. 9.[slideshare.net] Also watch for changes in the pulse pressure.[163.178.103.176]

  • Anaphylaxis

    Anaphylaxis causes your immune system to release a flood of chemicals that can cause you to go into shock — your blood pressure drops suddenly and your airways narrow, blocking[mayoclinic.org] Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting. Common triggers include certain foods, some medications, insect venom and latex.[mayoclinic.org]

  • Shock

    RATIONALE: Although anaphylaxis caused by jellyfish stings is common in coastal areas, an allergic shock caused by cooked jellyfish ingestion has never been reported in China. In this paper, we report a case of allergic shock being caused by ingestion of cooked salt-preserved jellyfish shortly after being stung by a[…][ncbi.nlm.nih.gov]
