A method and apparatus for non-invasively evaluating endothelial activity in a patient, particularly for indicating the presence of an endothelial dysfunction condition, by applying an occluding pressure to a predetermined part of an arm or leg of the patient to occlude arterial blood flow therein; maintaining the occluding pressure for a predetermined time period; removing the occluding pressure after the elapse of the predetermined time period to restore arterial blood flow; monitoring a digit of the arm or leg by a digit-probe for changes in the peripheral arterial tone therein before and after the application of the occluding pressure to the arm or leg of the patient; and utilizing any detected changes in the peripheral arterial tone for evaluating endothelial activity in the patient. Particularly important advantages are provided when the occluding cuff is applied to the digit of the patient receiving the monitoring digit-probe, on the proximal side thereof with respect to the patient's heart, and also when a reference digit-probe is applied to another digit, not influenced by the occluding pressure, to compensate for shifts inherent to vascular beds.

A method and system for use in measuring the endothelial dysfunction utilizing flow mediated dilation and determining arterial health of a patient. The system includes a non-invasive blood pressure monitor, an ultrasound system and a pulse oximeter monitor that all communicate with each other to perform the flow mediated dilation. Initially, the ultrasound transducer, blood pressure cuff and pulse oximeter sensor are positioned on an arm of the patient. The blood pressure cuff is inflated to occlude an artery for an occlusion period. Following the occlusion period, the ultrasound system is automatically signaled to begin determining a parameter of the artery, such as diameter, and the flow rate of blood through the artery without any operator intervention. At the same time, the pulse wave velocity PWV is calculated between the ultrasound transducer and the finger probe of the pulse oximeter following the occlusion period. Based upon the detected characteristics of the artery before and after occlusion, as well as the PWV, the system can determine the endothelial dysfunction and arterial health of the patient.

Methods are provided for using a compound to treat, for example, endothelial dysfunction including vascular abnormalities. More specifically, methods are described for using an oligosaccharide compound or glycomimetic compound wherein a cyclohexane derivative is incorporated in either.

The combination of a HMG CoA reductase inhibitor like a statin, such as simvastatin, with a pFox inhibitor such as trimetazidine (“Simetazidine”) is particularly advantageous for treatment of end-stage complications, such as acute coronary syndrome (ACS) and chronic angina, especially in type II diabetics. The combination therapy is also useful in the treatment and/or prevention of chronic heart failure (CHF) and peripheral arterial disease (PAD). The combination of a nitric oxide (NO) mechanism with increased NO production with pFox inhibition simultaneously treats both the effect and the cause of angina. One or more oral hypoglycemic compounds (biguanides, insulin sensitizers, such as thiazolidinediones, α-glucosidase inhibitors, insulin secretagogues, and dipeptidyl peptidase IV inhibitors), protein kinase C (PKC) inhibitors, and acetyl-CoA carboxylase inhibitors can also be used in combination with the HMG CoA reductase inhibitors and/or pFox inhibitors, especially in type II diabetics, to control glucose levels and treat endothelial dysfunction. The drugs can be given in combination (e.g. a single tablet) or in separate dosage forms, administered simultaneously or sequentially. In the preferred form the statin is given in a dose of between 5 and 80 mg/day in two separate doses, and the pFox inhibitor is administered in a sustained or extended dosage formulation at a dose of 20 mg three times a day or 35 mg two times a day. The dose of the oral hypoglycemic, PKC inhibitor, or acetyl-CoA carboxylase inhibitor varies with the type of drug used.

Methods are provided for preventing or treating risk factors for cardiovascular disease in an individual, comprising administering a therapeutically effective amount of a composition comprising an estradiol metabolite to said individual. Such risk factors include obesity, the metabolic syndrome, diabetes mellitus, vascular disorders, and renal disorders. Preferred estradiol metabolites include 2-methoxyestradiol, 4-methoxyestradiol, 2-hydroxyestradiol, and 4-hydroxyestradiol or prodrugs thereof. The compositions may also be in the form of a controlled release formulation. Methods are also provided for use of estradiol metabolites to treat or prevent insulin resistance, vascular endothelial dysfunction, hyperlipidemia, hypertension, diabetic nephropathy, proteinuria and reducing leptin levels. In addition, the methods provide a method of stabilizing glucose levels. These treatments may be used in either gender because of their lack of a feminizing estrogenic effect.

Hyper-inflammatory responses can lead to a variety of diseases including sepsis. It is now shown that extracellular histones released in response to inflammatory challenge are mediators contributing to endothelial dysfunction, organ failure and death during sepsis. As such, they can be targeted pharmacologically by inhibitors, as well as used as biomarkers for prognosis of sepsis and other diseases.
