Dose-dependent acute effects of passive smoking on left ventricular cardiac functions in healthy volunteers.

Objective: We have previously shown that acute passive smoking impaired left ventricular diastolic function in healthy volunteers. The aim of this study was to determine whether length of exposure and/or ambient smoke concentration is the key determinant of this outcome.

Methods: We measured blood carboxyhemoglobin (COHb)and lactate level to investigate the acute effects of passive smoking on tissue oxygenation.

Acute effects of passive smoking on left ventricular systolic and diastolic function in healthy volunteers.

Background: The aim of this study was to investigate the acute effects of passive smoking on left ventricular (LV) function in healthy volunteers.

Methods: Sixty-one healthy nonsmoking volunteers were enrolled in this study. LV M-mode, two-dimensional, conventional Doppler, and color tissue Doppler echocardiography were performed, and carboxyhemoglobin (COHb) levels were obtained from subjects before and immediately after exposure to passive smoking for 30 min in a smoking room.

Normal standards of eye projection in Turkish children 6 to 17 years of age.

Background: There are a few international and Turkish reports on children's eye projection references.

Methods: This is a cross-sectional study. Data were obtained from the second study of the Determination of Anthropometric Measurements of Turkish Children and Adolescents study group (DAMTCA II).

Acute effects of passive smoking on blood pressure and heart rate in healthy females.

Objects: Carbon monoxide (CO) is suspected of playing a major role in cigarette smoke-induced cardiovascular diseases. Hypertension is one of the common chronic cardiovascular diseases that lead to heart attacks, strokes, chronic heart failure, and chronic renal failure. We aimed to investigate the immediate effects of passive smoking on blood pressure and heart rate during and after exposure in healthy females.
