We describe the creation of a rat model of pressure overload induced moderate remodeling and early systolic dysfunction where signal transduction pathways involved in the initiation of the remodeling process are activated. This animal model will aid in identifying molecular targets for applying early therapeutic anti-remodeling strategies for heart failure.

The CODA 8-Channel High Throughput Non-Invasive Blood Pressure system measures the blood pressure in up to 8 mice or rats simultaneously. This tail-cuff system uses Volume Pressure Recording (VPR) to measure the blood pressure by determining the tail blood volume.
FAQs
Changes in cardiac output, arterial stiffness, and vascular resistance can alter the pressure value together rather than independently. Cardiac output represents the heart’s contribution, while stiffness and resistance describe properties of the arterial and vascular environment. Considering these interacting influences helps engineers and clinicians interpret systolic pressure as a hemodynamic signal instead of treating it as an isolated number.
Elevated or reduced readings can support the detection of abnormal hemodynamics, making the measurement relevant to cardiovascular assessment. In bioengineering, accurate values help distinguish meaningful changes in circulatory behavior from measurement problems. This information can guide evaluation of vascular function and support the development or assessment of devices and treatments associated with altered arterial pressure.
Systolic pressure provides a measurable cardiovascular variable for models that examine circulatory behavior. Relating this value to cardiac output, arterial stiffness, and vascular resistance allows bioengineers to represent interactions between the heart and vascular system. Such models can support the study of hemodynamics and contribute to personalized approaches for devices or treatments.
A cuff or a pressure sensor can provide systolic pressure measurements as part of blood pressure assessment. Bioengineering applications extend these measurement approaches into wearable monitors and catheter-based sensors. The selected device depends on the intended monitoring context, while accurate sensing remains essential for evaluating vascular function, abnormal hemodynamics, and device performance.
Calibration helps ensure that wearable monitors and catheter-based sensors produce measurements suitable for cardiovascular assessment. Because systolic pressure informs evaluation of vascular function and abnormal hemodynamics, inaccurate device output could weaken those assessments. Bioengineers therefore incorporate calibration into device development so measurements can support reliable monitoring and more personalized cardiovascular applications.
These measurements are useful when researchers evaluate vascular function, investigate abnormal hemodynamics, or develop cardiovascular devices and treatments. They also contribute to personalized monitoring by providing information relevant to an individual’s arterial pressure. In bioengineering, the same measurements connect sensor design, cardiovascular modeling, and clinical assessment within a shared quantitative framework.
