Three recent experimental studies focused on low consumption / exposure.949596 In one study, 29 smokers each consumed a single cigarette, immediately after which they had a significant decrease in blood vessel output power and significant increase in blood vessel ageing level and remaining blood volume 25 minutes later, as markers of atherosclerosis.94 In another study, human coronary artery endothelial cells were exposed to the smoke equivalent to one cigarette, which led to activation of oxidant stress sensing transcription factor NFR2 and up - regulation of cytochrome p450, considered to have a role in the development of heart disease.95 These effects were not seen when heart cells were exposed to the vapour from one e - cigarette.95 A study exposed adult mice to low intensity tobacco smoke (two cigarettes) for one to two months and found adverse histopathological effects on brain cells.96

Gastric enlargement forces the diaphragm into the chest, decreasing lung volume, and also compresses the blood return to the heart, which decreases cardiac output and cardiac dysrhythmias occur.

In AFib, the upper chambers of the heart — the atria — do not contract, which results in a decrease in blood volume pumped from the heart to the rest of the body.

Dehydration decreases the volume of blood, which reduces oxygen delivery and waste removal.

As the valve degenerates, blood can flow backwards through the valve, resulting in volume overload on the heart, and a decrease in blood flow out of the heart into the body.

Additionally, hemolysis results in release of analytes and enzymes from red blood cells (RBCs), which can falsely elevate many test results.5 Destruction of RBCs yields a lower RBC count.1 Excess fluid released from the lysed RBCs also creates a dilution effect in serum and can result in an artifactually decreased packed cell volume.

Since the amount of blood pumped by the heart per minute (cardiac output) is the product of the amount of blood ejected per contraction (stroke volume) and the heart rate in beats per minute, this decreased chamber volume (and subsequent stroke volume) results in an increased heart rate (tachycardia) as a reflex mechanism to maintain cardiac output and blood pressure.
