For high blood pressure to cause heart attack how long must it be high?

For high blood pressure to cause heart attack how long must it be high?

Impossible to answer: Believe it or not, htn, while a risk factor, is a relatively weak risk factor for heart attack. It's a big risk factor for stroke and congestive heart failure. (also kidney failure). Generally, risk factors must be present for decades to cause a heart attack, thus the "coronary prone age" is usually considered to be >55 for men and >65 for women (with many younger exceptions!). ...Read more

Hypertension (Definition)

A blood pressure reading has two numbers: a systolic blood pressure and a diastolic blood pressure. The systolic blood pressure is the maximum pressure the blood exerts on the vessels when the heart is beating. The diastolic blood pressure is the pressure the blood exerts on the vessels in between heartbeats. Hypertension, or high blood pressure, begins when the systolic blood pressure remains above 140 or when the diastolic blood pressure remains above 90. Hypertension can be a result of increased blood flow through vessels or increased resistance to ...Read more

Can it take many years for high blood pressure to cause heart attack ?

Can it take many years for high blood pressure to cause heart attack ?

Yes: High blood pressure along with high cholesterol, smoking, diabetes, family history all contribute to the development of atherosclerosis. It is the rupture of these plaques in coronary arteries that causes heart attacks. It takes years to develop significant atherosclerotic plaques. ...Read more

How high and low does your blood pressure have to get to where its considered dangerous?

How high and low does your blood pressure have to get to where its considered dangerous?

It's not the numbers: A normal BP is less than or equal to 135 on top and 85 on bottom. The lower, the better unless you're dizzy or passing out. Some very healthy people normally run a BP of 80-90 on the top number and that's fine. High bps increase long term risk. Very high bps (like >200/>110) that are also associated with symptoms like chest pain, breathlessness or confusion are considered an emergency. ...Read more

How would having a high blood pressure lead to cardiovascular disease?

How would having a high blood pressure lead to cardiovascular disease?

Several mechanisms: - damages blood vessels by harming cells lining them. - causes increased work/strain for heart muscle, causing it to enlarge (like any muscle that gets worked) ; over time, this process may result in impaired relaxation of heart (so it can't fill with blood) and dilation and weakening. High BP may cause hard/stiffening/narrowing of blood vessels (and thus not enough flow) also. ...Read more

Can blood pressure indicate heart attack and bleed on the brain if so would it be high or low?

Can blood pressure indicate heart attack and bleed on the brain if so would it be high or low?

No, not reliably: Consequences of heart disease or stroke on blood pressure and visa versa, the effect of blood pressure on the heart or brain, is not uniform. Clearly markedly elevated blood pressure is a risk for stroke and increases the work on the heart, but patients with normal blood pressure can still experience a stroke or have a heart attack. There are many other factors to consider ...Read more

How high does your heart rate need to be to have a heart attack?

How high does your heart rate need to be to have a heart attack?

No simple answer: If your arteries have no blockage, then there is no heart rate that will cause a heart attack. The more blocked the arteries, the lower the hr needed to outstrip the blood supply. There are other factors too, like presence/absence of anemia, hypertension, left ventricular hypertrophy, (wall thickening), and contractility which determine how much blood the heart is using and needs. ...Read more

Could it be bad for the heart if you have high cholesterol and low blood sugar?

Could it be bad for the heart if you have high cholesterol and low blood sugar?

Yes: It'll mostly be the cholesterol that's doing it. High sugars can cause damage to the heart arteries too, but i'm unaware of low sugar doing the same. That said, most people with documented low sugars are diabetics taking meds for the condition, and such patients almost invariably have a degree of heart artery involvement from their condition. ...Read more

Myocardial Infarction (Definition)

Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...Read more

Blood Pressure (Definition)

Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more
