The heart is the primary organ responsible for generating blood pressure through its contraction [1], and it actively regulates blood pressure by adjusting its rate and contractility in response to fluctuations [2]. Furthermore, the heart is considered a fundamental organ of blood pressure [3], and its dysfunction or oxygen demand imbalances are directly linked to pathological changes in blood pressure levels {fact:1, fact:4, fact:5}.

claimWhen blood pressure falls, the heart increases its rate and contracts more strongly to compensate.
claimA positive feedback loop involving heart damage occurs when an imbalance between oxygen demand and oxygen supply lowers blood pressure, causing the body to stimulate the heart further, which leads to additional heart damage and potentially death.
claimAn imbalance between the heart's oxygen demand and oxygen supply can create a positive feedback loop where the heart is stimulated to work harder, causing further damage and lower blood pressure, which continues until death.
claimBlood pressure is initially generated by the contraction of the heart.
A Copernican Approach to Brain Advancement: The Paradigm of ... frontiersin.org 2 facts
claimHomeostasis models the cause of hypertension by pointing to abnormal functionality of the heart, blood vessels, kidneys, or molecular signaling, whereas allostasis explains that the brain deliberately directs these organs on an anticipatory basis to elevate blood pressure for the delivery of resources like glucose and oxygen to large muscle groups.
claimIn scientific research, the brain is considered the organ of behavior, analogous to how the heart, vascular system, and kidneys are considered the organs of blood pressure.

claimThe brain regulates blood pressure by monitoring sensors in the body and signaling the cardiovascular system to slow the heart and open blood vessels, and signaling the kidneys to excrete fluid when pressure is too high.
claimHigh levels of hydrogen and potassium ions cause a weakened heart and lower blood pressure.
