The golden ratio in the pulmonary circulation in patients with heart failure and cardiogenic shock

open access: yesPhysiological Reports, Volume 13, Issue 7, April 2025.
Stroke volume is a determinant of both mPAP (left wireframe plot) and PP (right surface plot). Mean pulmonary artery pressure changes with SV with a coefficient of (PVR/t, where t = cardiac interval). The mPAP plot is based on a PVR of 4.2WU (or 0.252 mmHg/mL.s) at cardiac intervals from 400 to 1000 ms and PAWP of 29 mmHg.

Cardiac tamponade

Nature Reviews Disease Primers, 2023
Cardiac tamponade is a medical emergency caused by the progressive accumulation of pericardial fluid (effusion), blood, pus or air in the pericardium, compressing the heart chambers and leading to haemodynamic compromise, circulatory shock, cardiac arrest and death.

Cardiac Tamponade

Surgical Clinics of North America, 1975
Cardiac tamponade is an insidious and often fatal complication which can occur on any service, in many diseases, and at any age. The increasing pressure within the pericardium prevents ventricular filling and depresses cardiac output, coronary and systemic perfusion, and venous return.

Cardiac Tamponade

Cardiology Clinics, 1990
Hemodynamic abnormalities induced by pericardial effusion can be categorized by stages. During phase I, pericardial and left and right ventricular pressures are elevated but not equilibrated, and cardiac output is not compromised. During phase II, elevated pericardial and right ventricular filling pressures are equilibrated with each other but not with
