Excessive sodium: High urinary levels of sodium result in increased levels of calcium. Certain defects in the kidney tubules transport system, which cause imbalances in sodium and phosphate, can lead to high calcium levels in the urine. A diet high in salt can also produce this effect.
Some of the common causes of Decreased cardiac output may include: 1  Mitral regurgitation. 2  Azotemia. 3  Hypotension. Cardiac tamponade.  Restrictive 1  cardiomyopathy. more causes...Â».
â¢ With increased stroke volume, due to increased venous return and/or increased contractility, there. is an increased cardiac output and increased blood pressure. Page 15. Summary. â¢ Increases in peripheral resistance, blood volume, and cardiac output result in higher blood pressure. Conversely decreases in any of these factors lead to lower blood pressure. â¢ Three main sources of peripheral resistance: Blood vessel diameter, blood viscosity, and total vessel.
