Can short-term heart rate variability predict coronary artery disease in patients undergoing elective coronary angiography due to typical chest pain?

Background: Presence of typical chest pain and normal coronary angiography suggests the possibility of microvascular ischemia of the myocardium as well as other non-cardiac causes that are also likely to decrease heart rate variability (HRV). This raises a question of whether poor HRV can predict abnormal elective coronary angiography (ECA).

Aim: The aim of this study was to compare HRV in patients with typical chest pain when they are classified according to ECA outcomes.

Indicators of metabolic syndrome in normotensive normoglycemic asthmatic patients.

Background: Pathophysiology of hypertension and bronchial asthma (BA) shares many similarities, especially those related to the metabolic syndrome (MS).

Aim: In this study, the indicators of the MS were evaluated in normoglycemic normotensive asthmatic patients to clarify if the components of the MS can still interact to increase the risk of BA, provided that blood pressure and glucose level are kept within the normal physiological ranges.

Methods: Body mass index (BMI), waist circumference (WC), mean arterial blood pressure (MABP), fasting blood glucose (FBG) and fasting blood insulin (FBI) levels, the quantitative insulin sensitivity check index (QUICKI), serum lipid profile, and spirometric measurements were all compared between 120 asthmatic patients and 59 non-asthmatic subjects.

Thyroid hormones profile among obese pregnant Sudanese women.

Background: Previous studies evaluating thyroid function among obese pregnant women failed to demonstrate a consistent pattern of thyroid hormones profile, probably due to the variations in biological/environmental determinants of thyroid function in different countries.

Aim: The aim of the study was to evaluate thyroid hormones profile in Sudanese pregnant women with varying degrees of obesity.

Patients And Methods: Obstetric/sociodemographic characteristics were gathered from 178 singleton pregnant Sudanese women using questionnaires.

Chest Pain Characteristics in Cardiac Syndrome X Compared to Coronary Artery Disease.

Aim: This study aimed to assess if clinical remarks gained by analysis of the present and past medical history of patients undergoing elective coronary angiography (ECA) due to typical chest pain can help to predict the outcome of ECA.

Material And Methods: One hundred and fifty-four ECA candidates with a history of typical chest were seen on the same day intended for ECA in the cardiac centre of AlShaab Teaching Hospital, Khartoum, Sudan. The details of the present complaints, characteristics of chest pain, past medical and socioeconomic history were recorded from each subject guided by a questionnaire.
