What is J-curve phenomenon in hypertension?
The J-curve effect describes an inverse relation between low blood pressure (BP) and cardiovascular complications. This effect is more pronounced in patients with preexisting coronary artery disease (CAD), hypertension or left ventricular hypertrophy (LVH).
What is J-curve Phenomena?
In cardiovascular (CV) medicine, the J-curve phenomenon arises when a risk factor becomes inversely related to risk below a certain point, whereas the more widely accepted positive risk association exists across most of the observed risk factor distribution.

What is the reason of J-curve effect?
The J-curve effect is often cited in economics to describe, for instance, the way that a country’s balance of trade initially worsens following a devaluation of its currency, then quickly recovers and finally surpasses its previous performance.
What is an example of J-curve?
The J-curve theory recognizes that import and export quantities and prices are often arranged in advance and set into a contract. For example, an importer of watches is likely to enter into a contract with the foreign watch company to import a specific quantity over some future period.
What is the best medicine to lower diastolic blood pressure?
Angiotensin converting enzyme inhibitors and angiotensin receptor blockers have been shown to be effective in improvement of measures of diastolic function and are recommended as first-line agents in the control of hypertension in patients with diastolic heart failure.
What medications treat diastolic hypertension?
What medications treat diastolic hypertension?

Blood pressure naturally drops at night, increases through the day, peaks at midday, and stays high through the afternoon before decreasing in the evening. This is affected by the circadian rhythm among other factors, like exercise, food and drink, and stress.
What causes orthostatic or postural hypotension?
Orthostatic hypotension — also called postural hypotension — is a form of low blood pressure that happens when standing after sitting or lying down. Orthostatic hypotension can cause dizziness or lightheadedness and possibly fainting.
What is an example of J Curve?
What is J-shaped?
J-shaped growth curve A curve on a graph that records the situation in which, in a new environment, the population density of an organism increases rapidly in an exponential or logarithmic form, but then stops abruptly as environmental resistance (e.g. seasonality) or some other factor (e.g. the end of the breeding …
