regulation of the force of heart contraction

Definition

Target type: biologicalprocess

Any process that modulates the extent of heart contraction, changing the force with which blood is propelled. [GOC:dph, GOC:tb, PMID:10358008]

The force of heart contraction, known as contractility, is meticulously regulated by a complex interplay of factors that ensure the heart pumps blood effectively throughout the body. This intricate process involves the coordinated action of electrical and mechanical components, driven by intricate signaling pathways that influence the heart muscle's ability to contract.

**1. Electrical Conduction and Calcium Release:**
The heart's electrical activity is orchestrated by specialized cells called pacemaker cells, which initiate the rhythmic impulses that propagate throughout the heart. These impulses travel through a network of conduction pathways, leading to the depolarization of heart muscle cells (cardiomyocytes). Depolarization triggers the opening of voltage-gated calcium channels on the cell membrane, leading to a surge of calcium ions into the cell's cytoplasm.

**2. Calcium-Induced Calcium Release:**
This influx of calcium ions triggers a critical process known as calcium-induced calcium release. Calcium ions bind to a protein called ryanodine receptor (RyR), located on the sarcoplasmic reticulum (SR) – an intracellular organelle responsible for storing calcium. This binding event prompts the RyR to release a massive amount of calcium ions from the SR into the cytoplasm, further increasing intracellular calcium levels.

**3. Muscle Contraction:**
This elevated intracellular calcium concentration is the key to muscle contraction. Calcium ions bind to troponin, a protein complex attached to the thin filaments (actin) of the sarcomere – the fundamental unit of muscle structure. This binding event initiates a conformational change in troponin, which in turn shifts tropomyosin – another protein associated with actin – away from the myosin binding sites on actin. This exposes the binding sites, allowing myosin, a protein located on the thick filaments, to bind to actin. Myosin then undergoes a power stroke, pulling the actin filaments towards the center of the sarcomere, resulting in muscle contraction.

**4. Relaxation and Calcium Reuptake:**
Following contraction, calcium levels need to be reduced to allow the muscle to relax. This is achieved by the active reuptake of calcium ions back into the SR via a calcium ATPase pump (SERCA). The SR actively pumps calcium back into its lumen, lowering the intracellular calcium concentration. As calcium detaches from troponin, tropomyosin re-covers the myosin binding sites on actin, halting the contraction cycle and allowing the muscle to relax.

**5. Factors Influencing Contractility:**
The force of heart contraction is influenced by various factors that modulate the intricate processes outlined above:

* **Sympathetic Nervous System:** The sympathetic nervous system, the “fight-or-flight” system, releases norepinephrine, a neurotransmitter that binds to β-adrenergic receptors on cardiomyocytes. This activation increases the opening of calcium channels, promoting calcium influx and enhancing contractility.
* **Parasympathetic Nervous System:** The parasympathetic nervous system, the “rest-and-digest” system, releases acetylcholine, which binds to muscarinic receptors. This action decreases heart rate and slightly reduces contractility.
* **Hormones:** Hormones such as epinephrine, thyroid hormones, and digitalis can also influence contractility by modulating calcium levels and the activity of signaling pathways involved in muscle contraction.
* **Calcium Sensitivity:** The sensitivity of the contractile proteins (troponin and tropomyosin) to calcium can be modified by factors like phosphorylation, leading to changes in contractility.
* **Preload and Afterload:** The preload, or the stretching of the heart muscle before contraction, and the afterload, or the resistance the heart must overcome to eject blood, also play a role in contractility.

**6. Disorders of Contractility:**
Dysfunctions in any of these regulatory mechanisms can lead to heart problems. Reduced contractility can lead to heart failure, while excessive contractility can contribute to arrhythmias.

In summary, the regulation of heart contraction is a tightly controlled process involving a complex interplay of electrical, mechanical, and biochemical events. It is a critical physiological function that ensures efficient blood circulation throughout the body. Any disruptions in this delicate balance can have significant consequences for cardiovascular health.'
