CVD is the main cause of death in men in all but 12 countries of Europe and is the main cause of death in women in all but two countries. CVD mortality is now falling in most European countries, including Central and Eastern European countries which saw considerable increases until the beginning of the 21st century.

Effect of salt on blood pressure[ edit ] Automated blood pressure device The human body has evolved to balance salt intake with need through means such as the renin—angiotensin system. In humans, salt has important biological functions. Relevant to risk of cardiovascular disease, salt is highly involved with the maintenance of body fluid volume, including osmotic balance in the blood, extracellular and intracellular fluids, and resting membrane potential.

Artery walls are analogous to a selectively permeable membraneand they allow solutes, including sodium and chloride, to pass through or notdepending on osmosis. Circulating water and solutes in the body maintain blood pressure in the blood, as well as other functions such as regulation of body temperature.

The water potential in blood will decrease due to the increase solutes, and blood osmotic pressure will increase. While the kidney reacts to excrete excess sodium and chloride in the body, water retention causes blood pressure to increase. Both studies were designed and conducted by the National Heart, Lung, and Blood Institute in the United States, each involving a large, randomized sample.

During the intervention phase, participants ate their assigned diets containing three distinct levels of sodium in random order.

Their blood pressure is monitored during the control period, and at all three intervention phases. See sodium sensitivity below. The techniques to reduce sodium included keeping a food diary and reading labels.

Cook and colleagues listed other effects of those techniques, including a reduction in fat and calories per day 11g, caland weight loss of 1 to 3 pounds.

Rather than create drastic salt policies based on conflicting data, Alderman and his colleague Hillel Cohen propose that the government sponsor a large, controlled clinical trial to see what happens to people who follow low-salt diets over time.

Appel responds that such a trial "cannot and will not be done," in part because it would be so expensive. But unless we have clear data, evangelical antisalt campaigns are not just based on shaky science; they are ultimately unfair.

But it is "based on wild extrapolations. They do also not support the current recommendations of a generalized and indiscriminate reduction of salt intake at the population level.

However, they do not negate the blood pressure-lowering effects of a dietary salt reduction in hypertensive patients.

In most studies, sodium sensitivity is defined as the change in mean blood pressure corresponding to a decrease or increase of sodium intake. The method to assess sodium sensitivity includes the measurement of circulating fluid volume and peripheral vascular resistance.

Several studies have shown a relationship between sodium sensitivity and the increase of circulating fluid volume or peripheral vascular resistance. Demographic factors which affect sodium sensitivity include race, gender, and age.

More specifically, haptoglobin phenotypes contribute to the characteristic of sodium-resistance in humans. The influence of physiological factors including renal function and insulin levels on sodium sensitivity are shown in various studies. Salt substitute The growing awareness of excessive sodium consumption in connection with hypertension and cardiovascular disease has increased the usage of salt substitutes at both a consumer and industrial level.Cardiovascular diseases (CVDs) are disorders of the heart and blood vessels and include coronary heart disease, cerebrovascular disease, rheumatic heart disease and other conditions.

The Heart Disease and Stroke Statistical Update is a major source for monitoring cardiovascular health and disease in the population.

Cardiovascular disease (CVD) is among the leading causes of death and disability worldwide. Since its beginning, the Framingham study has been a leader in identifying CVD risk factors.
