As you dive into the fascinating world of pharmacology, let’s take a moment to break down one of the most important drug classes you’ll encounter: antihypertensives. 💊 These medications are crucial for managing high blood pressure (hypertension), a major risk factor for cardiovascular disease.
Here’s a detailed overview to help you connect the mechanisms of these drugs to physiology:
Today, let’s explore the risk factors for hypertension and why they’re critical to understand. Identifying and addressing these factors is key to preventing and managing HTN in your future patients.
Hello students! Let’s take a closer look at a cornerstone of cardiovascular physiology: Blood Pressure Regulation and its normal range. Mastering this topic is essential for diagnosing and managing hypertension in your future practice.
An ECG is a simple, non-invasive test that records the electrical activity of the heart over a period of time. By placing electrodes on the skin, we can detect the tiny electrical changes that occur with each heartbeat. ⚡
Interpreting an ECG isn’t just about spotting abnormalities — it’s about understanding the heart’s electrical story in the context of the patient. This guide breaks down the process step by step.
Ischaemic heart disease (IHD), also referred to as coronary artery disease (CAD), describes a state in which myocardial oxygen supply is insufficient to meet myocardial metabolic demand.
At face value, that is a simple supply–demand mismatch. In reality, it reflects a complex, progressive, inflammatory disease of the coronary arteries that evolves over decades before becoming clinically apparent.
The heart extracts a very high proportion of oxygen from coronary blood at rest. Unlike skeletal muscle, it cannot simply extract much more when demand rises. When the myocardium needs more oxygen — during exercise, stress, tachycardia — the only way to meet that demand is to increase coronary blood flow.
To understand IHD properly, we need to follow the biology.
The heart isn’t just a pump — it’s a beautifully coordinated electrical organ.
Every beat begins with ions moving across membranes in a precisely coordinated sequence.
If you understand the ions, you understand the ECG.
If you understand the ECG, you understand arrhythmias.
Let’s build it from the ground up.
As medical students, mastering the cardiovascular system is essential—not just for exams, but for your future clinical practice. Let’s break down the heart’s anatomy, physiology, and key concepts in a structured, detailed way to help you build a strong foundation. Ready to dive in?
You’ll hear it described as “sharp chest pain,” “worse when lying flat,” or “relieved by sitting forward.” But what’s actually happening when someone has pericarditis—and how do we reason through it clinically?
Yes, this is exactly what it looks like... 😱
Ischaemic Heart Disease (IHD) and Acute Coronary Syndrome (ACS) are terms that often get used interchangeably—but they’re not the same. If you want to sound like you know what you’re talking about on ward rounds (or ace your exams), here’s what you need to remember.
