lower the amount of bad cholesterol in the blood. High levels of cholesterol can cause the arteries to narrow, increasing the risk of a heart attack.Not all people will experience side effects, but these can include nausea, vomiting, diarrhoea, headache, muscle aches, and inflammation of the muscles Diuretics, Loop diuretics, Potassium sparing diuretics Diuretics balance the amount of water and salt in the body and lower high blood pressure. They include thiazide diuretics, bendroflumethiazide, furosemide, bumetanide and spironolactone. ACE inhibitors and angiotensin II antagonists ACE inhibitors and angiotensin II antagonists relax and widen the arteries, which can lower blood pressure. They also increase the blood supply to the heart, which reduces the work it has to do to pump blood around the body. Beta-blockers Beta-blockers slow down or regulate the heartbeat by blocking the action of adrenaline on the heart. They include acebutolol, atenolol, bisoprolol, metoprolol, oxprenolol, pindolol, propanolol, sotalol and timolol. Anti-arrhythmic drugs These drugs speed up, slow or regulate the heartbeat, which can reduce the chance of heart failure. They include amiodarone, flecainide, propafenone and digoxin. ...read more.


Pacemakers are usually needed for people whose heart rate has become too slow. Heart block is the most common reason someone will need a pacemaker. This is where there is a delay in the electrical conduction of messages in the heart muscles. A pacemaker works by artificially taking over the role of the heart's natural pacemaker (the sino atrial node), either all of the time, or only some of the time when it is required. Coronary Artery Bypass Graft Surgery (CABG) Also known as bypass surgery, heart bypass, coronary artery bypass surgery. A blood vessel is inserted between the aorta and a part of the coronary artery beyond the narrowed or blocked area. This allows the blood to bypass the narrowed sections of coronary arteries. A heart bypass is carried out where the arteries become narrowed or blocked in patients with angina The fault of heart disease and the growing risk of it can be traced to the modern lifestyle. A lack of excerise for reasons such as not enough time between work and a general laziness contribute heavily to heart disease. Another main cause is the amount of unhealthy, fatty foods that are consumed and it is no suprise that it is mainly obese and overweight people who suffer from heart disease. ...read more.

    It reaches maximum concentration within an hour. The blood distributes it throughout the body. One effect of caffeine is to interfere with adenosine at multiple sites in the brain. Caffeine also acts at other sites in the body to increase heart rate, constrict blood vessels, relax air passages to improve breathing and allow some muscles to contract more easily.
