How does calcium affect vascular health?
The role of calcium in vascular health is less clear-cut. There are calcium-sensing receptors on vascular smooth muscle cells and on platelets, calcium plays a role in smooth muscle contraction and its role in the electrophysiology of the heart and myocardial function have already been alluded to. Calcium deposition in the vasculature is a consistent feature of vascular disease and is predictive of adverse cardiovascular events. Indeed, calcium deposition in other soft tissues (such as the kidneys or muscles) has adverse effects on tissue function, and to prevent this there is a complex system of mineralisation inhibitors (such as pyrophosphate, fetuin-A, matrix GLA protein etc.). Obviously, tissue-specific targeting of mineralisation regulation is critically important so that mineralisation of bone is promoted but that of all other tissues is prevented. With ageing, the effectiveness of these mechanisms appears to decline, particularly in the vascular system. In addition, blood calcium levels appear to influence the development of vascular disease.
What is the role of calcium in the body?
Calcium plays a number of critically important roles in physiology and pathology, in addition to its most widely recognised function as a critical structural component of bone. Many cells have calcium-sensing receptors, with evidence that the concentrations of calcium ions in the extracellular fluid directly regulate cell function (e.g., parathyroid, renal tubule, and many more). Extracellular calcium concentration directly impacts on cell membrane potentials, and so impacts on function of all excitable tissues, particularly the nervous system and the heart. Calcium is a key messenger in the contraction of muscle, including the myocardium. It is a co-factor for many enzymes and intimately involved in blood coagulation—indeed, calcium chelators (citrate, ethylenediaminetetraacetic acid [EDTA]) are the most commonly used anticoagulants in blood collection.
Does calcium affect coagulation?
Direct vascular effects are not the only possibility to be considered . Calcium is intimately involved in the coagulation pathway and also regulates platelet function via the calcium-sensing receptor [30]. Hypercalcaemia in rats accelerates clot initiation [31] and in human blood samples ionised calcium is associated with clot initiation and clot strength [32]. The increased platelet activation of patients with primary hyperparathyroidism also suggests that circulating calcium regulates coagulation in vivo[33] and this is further supported by increases in blood coagulability 4 hours after an oral calcium load in normal postmenopausal women [25].
Is calcium a risk factor for vascular disease?
Circulating calcium is a risk factor for vascular disease, a conclusion arising from prospective studies involving hundreds of thousands of participants and extending over periods of up to 30 years. These associations may be partially mediated by other cardiovascular risk factors such as circulating lipid levels, blood pressure, and body mass index, but there appears to be a residual independent effect of serum calcium. Polymorphisms of the calcium-sensing receptor associated with small elevations of serum calcium are also associated with cardiovascular disease, suggesting that calcium plays a causative role. Trials of calcium supplements in patients on dialysis and those with less severe renal failure demonstrate increased mortality and/or acceleration of vascular disease, and meta-analyses of trials in those without overt renal disease suggest a similar adverse effect. Interpretation of the latter trials is complicated by a significant interaction between baseline use of calcium supplements and the effect of randomisation to calcium in the largest trial. Restriction of analysis to those who are calcium-naive demonstrates a consistent adverse effect. Observational studies of dietary calcium do not demonstrate a consistent adverse effect on cardiovascular health, though very high or very low intakes may be deleterious. Thus, obtaining calcium from the diet rather than supplements is to be encouraged.
Do calcium supplements cause calcification?
The area of medical practice in which concern about the cardiovascular safety of calcium supplements has been enunciated for the longest is that of renal medicine. Hyperphosphataemia is present long before the need for dialysis arises, and this has been managed with a succession of phosphate-binding agents, including calcium supplements. Vascular calcification is evident on plain radiographs in many patients with renal failure and concern has been expressed that the use of calcium supplements might accelerate this phenomenon, resulting in even higher incidences of vascular events. As a result of these concerns, phosphate binders that do not contain calcium have also been developed and a series of trials carried out comparing mortality following the use of these agents. These studies have recently been meta-analysed with the finding that mortality is 20% lower in individuals using calcium-free binders [37]. It is important to note that two trials have been carried out in patients not yet requiring dialysis. In the first of these, Russo et al. [38] showed that calcium supplements increased coronary artery calcification when compared with sevelamer, a calcium-free phosphate binder. Subsequently, Di Iorio et al. [39] showed that mortality was 10% in sevelamer-treated patients with stage three or four chronic renal failure (mean baseline creatinine clearance 33 mL/min) but rose to 19% in those randomised to calcium. This is a finding of broad relevance, since many older patients who might consider taking calcium supplements for treatment or prevention of osteoporosis, have creatinine clearances in this range.
Is a calcium a risk factor?
CIRCULATING CALCIUM IS A RISK FACTOR FOR VASCULAR DISEASE
Is calcium a biologically significant endpoint?
Some writers have dismissed these excursions in serum calcium as having no biological significance. However, the associations between vascular events and mortality with variations in serum calcium within the normal range, make clear that differences of 0.05 to 0.1 mmol/L are indeed associated with clinically important endpoints. In the longitudinal studies relating serum calcium to vascular risk, it is assumed that the differences between individuals and serum calcium are sustained over time. Changes following food ingestion or calcium supplementation are transient, but do last for at least 6 to 8 hours, and are likely to be repeated each time a supplement is ingested. Indeed, we have shown that the excursion in serum calcium after a 1 g dose of calcium is at least as large in long-term users of supplements as it is in calcium-naive subjects (Fig. 2C) [36].
How does calcium affect my heart?
Besides your bones and teeth, calcium also affects organs like your heart. Calcium enters the muscle cells in your heart during every heartbeat. This helps coordinate the electrical signals that control how fast your heart beats. Calcium is also involved in helping the heart contract and pump blood to the rest of the body.
