Cardiovascular diseases affect many people, not only the elderly. The most common causes are our life-style choices: a stressful and hectic daily life, excessive demands on the job and elsewhere, unhealthy habits, smoking, a diet high in fat and lack of exercise. All these factors combine to overburden the heart and blood vessels, thus compromising their function. The resulting symptoms can often be relieved by simple means. However, these symptoms may also be evidence of a serious underlying condition. If you have heart problems, you should always seek advice and/or a proper diagnosis from a healthcare professional.
